Gun Accessories

Go To
Who needs a close-range backup weapon? Your sniper scope has a reflex sight for that.

Gun Salesman: You'll probably want the accessory kit: Holster. Bandolier. Silencer. Loudener. Speed-cocker. Aaand [pulls out attachment much larger than the gun itself] this one's for shooting down police helicopters.
Homer: Oh, I don't need anything like that. Yet...

There are Cool Guns, but when your gun isn't cool enough by itself, what do you do? Why, you attach a ton of junk to it, of course! Tacticool.

What sort of toys can you attach to a gun? Take a gander at the Useful Notes page.

As well as all that, you might have non-slip coated surfaces on the weapon to make it easier to handle, as well as camo; most weapons with synthetic furnishings come in a single colour, so additions might be anything from boot polish to actual paint or even bits of foliage. There's also the option of changing the grips for ones more ergonomic than the standard, enlarging or otherwise altering the various levers and controls, changing the trigger and trigger guard, replacing synthetic furnishings with wood or vice versa, or adding tasteless plated finishes and engraving.

Often, more distinctly fictional devices are present, like X-ray scanners, heartbeat monitors, or pointless glowing whatsits. A classic is a visible ammo counter, popularized by Aliens and often used by video games to provide a Diegetic Interface. A recent trend in video games is to depict accessory parts as quick-swappable; any potential issues with having to re-zero scopes are glossed over, due to Rule of Cool and Rule of Fun.

See also IKEA Weaponry, Scaramanga Special, and Swiss Army Gun. Often a Sub-Trope of Gun Porn. For accessories for guns you're supposed to wear, see Badass Bandolier. Note that with regard to video games, the important thing is that there are physical additions to the weapon; just being able to boost abstract stats to power up weapons isn't this trope, that would be Socketed Equipment. If the accessory itself is another kind of weapon, you may have a Mix-and-Match Weapon, Combo Rifle, or Bifurcated Weapon on your hands. If the accessory in question is a gunlight, expect batteries to never be an issue.

This page mounts the following accessories:

    open/close all folders 

  • Lampshaded in the 2010 OVA of Cat Shit One, where Packy chastises Bota about putting so much unnecessary stuff on his rifle, remarking that the extra weight will only serve to slow him down. Even Bota half admits that he does it for Rule of Cool purposes, but is later vindicated when his oversized scope helps block a terrorist's sword swing.

     Comic Books 
  • In one strip of the Swedish comic Hälge, the local though-guy Uffe decided that a silencer was to sissy, so he attached an amplifier instead. Edwin who was next to him was visibly shaken by the thing.
  • Parodied in Marvel's What The—? comics with The Pulverizer, as seen here.

     Card Games 
  • The Good, the Bad & the Munchkin has the Seven-Gun, which is a Six-Gun with a tiny single-shot pistol attached to the barrel. The right array of enhancement cards can turn it into My Grandpappy's Steam-Powered Seven-Gun With Unlimited Ammo.

  • Plan 7 of 9 from Outer Space by Odon. Captain Proton contacts a virtual gunshop and is offered a selection of lethal weaponry culminating in the BFG-USBFOMGROFLMFAOWTFUBARSNAFUA1 Individual Integrated Modular Combat Assault Weapon. The number of accessories that can be attached to its top, side, and bottom-mounted accessory rails is a very Long List.

  • In The Naked Gun 2 1/2, Nordberg pulls back the slide of his pistol and adds an accessory. Then another. Then another. Eventually he's sitting in a full-size antiaircraft gun.
  • Another parody was in Beverly Hills Cop III, which featured an advert for the "Annihilator 2000," a comically over-featured weapon including such extras as a phone, fax machine, CD player and microwave oven (marketed as "the weapon for the modern survivalist" and said several celebrities owned it, like Stallone). Thankfully, once he figured out which switch did what, the integral heavy machine gun and rocket launcher ended up being helpful.
  • In The Terminator, Arnold Schwarzenegger used an AMT Hardballer Longslide equipped with a very early "Laserlock" sight; the prop actually worked, though it ran off a battery pack taped to his back and was triggered using a switch in his other hand, with each connected to the battery by cords going up both of Arnold's sleeves.
  • Robocop's gun was a Beretta 93R fitted with an enormous ported compensator designed to produce a huge horizontal muzzle flash. The compensator was necessary, because otherwise the gun would have looked pitifully small on the Robocop suit's hands (giving Robo a Desert Eagle (which was his sidearm on the original script) was discarded because of this).
  • In Equilibrium, the Clerics use similar weapons; these are converted Beretta 92s with fullauto drop-in sears, M16-style fire selectors and a variety of additional extras, including self-balancing magazines with rounded bases, and magazines with integral blade-things in the base for clubbing people with.
  • In The Living Daylights, Dalton uses a Walther WA2000 equipped with a rather large night vision scope and his own hand-loaded ammunition.
    • In the same movie, arms dealer Whitaker shows off a collection of firearms with silly Hollywood embellishments such as mini-missile launchers, and in the final confrontation pulls out a Colt Commando carbine fitted with a transparent gun shield.
  • Eraser featured a scientifically ridiculous railgun with a matching scope; a special X-ray sight that could somehow look through concrete and still see the target's beating heart.
  • Aliens popularized guns with built-in ammo counters; the Pulse Rifles used a very 80s system with simple 7-bar LED displays.
    • Moonwalker featured weapons with the same feature (and oversized attached flashlights) issued to soldiers of the overacting drug lord.
  • Johnny Mnemonic has one scene that weirdly inverts this. Johnny takes an assault rifle, starts stripping parts off it and winds up with a heavy-looking handgun.
  • Similarly inverted in Escape from New York, where the United States Police use M16's with their handguards removed, rather than with any additions. That was probably to give them an unfamiliar 'futuristic' look, rather than because the police liked scorching their hands.
  • Hogarth Hughes duct-tapes a flashlight to his BB gun in The Iron Giant.

     Live-Action TV 
  • Sledge Hammer!'s own invention was a special accessory for revolvers. He calls it the "loudener."
  • The Man From Uncle featured a series of custom Walther P38 pistols with various accessories including stocks, barrel extensions and scopes. They proved so popular that the guns received their own fan mail, and Megatron from Transformers was originally a toy version of the UNCLE gun.
  • Watch enough Stargate SG-1, and you'll see all kinds of weapon accessories. The most commonly accessorized gun is the MP5, usually with a scope or ACOG of some sort (which is a bit optimistic regarding the MP-5's effective range), or a side-by-side magazine holder, but the P90 featured later got in on the act a few times, and light machine guns were rarely stock.
    • Alien technology was also used in some cases to accessorize the weapons, such as a Goa'uld combat-training device to turn them into non-lethal stun weapons and an attachment that makes them lethal to Kull Warriors.
  • Flashpoint shows the police officers using various accessories on their (Weaver Rail) guns, especially tactical flashlights, foregrips, and ACOG scopes. Oddly enough, they almost never actually use the foregrips on their guns.
    • Ed spends one episode with what appears to be a Cornershot mount for his pistol which he uses as if it were a rifle rather than for its intended function.
  • Sons of Guns now features the Docudrama in tacticool format.
  • Star Trek: Deep Space Nine features the TR-116 rifle (a rare example of a gun that uses physical bullets rather than energy beams) which can be upgraded with an exographic targeting sensor and a micro-transporter, allowing it to be used to kill anyone from anywhere. Three Red Shirts learn that the hard way.
  • In Ultraviolet, the government vampire-killers have digital cameras attached to their weapons instead of gun-sights, even for close-range fights. There is a reason for this - Code V's don't show up on any form of analogue or digital camera equipment, so comparing what is visible on the camera's screen to what your eyes can see acts as an instant way of distinguishing undead from living.

     Tabletop Games 
  • Shadowrun includes gas vents and shock pads, which provide recoil compensation, gyro stabilization, which offset recoil and movement penalties, sound suppressors, which are silencers for automatic weapons, bipods and tripods, which provide recoil compensation for heavy weapons, and smartgun systems, which tell you when your weapon is pointing at its target among other things. Although the ultimate in gun accessories has to be three choices for a propulsion system or the pilot upgrade.
  • Call of Cthulhu supplement Terror from the Stars, section "Field Manual of the Theron Marks Society". The title Investigator group would tape flashlights on top of firearms so they could fire at targets in the dark. Eventually they designed custom mounts on the weapons to hold the flashlights.
  • One such weapon is described in GURPS: Gun Fu owned by one "Bubba Lee Jones": Colt M4A1 carbine with twin-drum magazine, a reflex sight, night sight, a tactical light and a targeting laser. He calls her Dita.
    • He even gets bonuses for using Dita since he took the Tacticool perk.
  • A common weapon upgrade in Warhammer 40,000 is to turn a gun into a Combi-Weapon. Start with a standard Bolter - that is a semi-automatic weapon that fires armor-piercing, mass-reactive, explosive gyrojet rounds - then add a one-shot Flamer, Meltagun, or Plasma Gun to it. Chaos forces use Combi-Bolters, two Boltguns slapped together, as the archaic predecessor to the loyalist Storm Bolter.
    • The RPGs Dark Heresy, Rogue Trader, and Deathwatch all have some stuff you can put on a gun. Dark Heresy starts out relatively harmless, with the obligatory silencer, scope and red-dot laserpointer. Rogue Trader and Deathwatch go a little further, supplying anti-grav gadgets that let you use a heavy full-auto rpg launcher while moving and, in the latter case, a chainsaw bayonet. Rogue Trader's expansion Into The Storm finally also featured Orks as playable characters, including Mekboyz and a few upgradez and kustom jobz they like to inflict on their guns in their quest for More Dakka. Among them is a loudener which enhances the noise made by guns to ridiculous levels and makes suppressive fire more effective.
    • Da Orks have a unit obsessed with this trope. Flash Gitz are rich greenskins who sink their fortunes into improving their Snazzguns by slapping all manner of additional barrels, ammo feeds, useless sights, clever gubbinz, know-wots, and other shooty bitz onto the weapons. In game terms this means that you can purchase upgrades like "Shootier" (hit harder), "Blasta" (better at penetrating armor), and of course "More Dakka" (improved rate of fire). Despite all this, Flash Gitz are generally regarded as a terrible unit since no matter what kind of gun they're holding, it's still an Ork shooting it.

  • NERF N-Strike blasters have Tactical Rails for you to pimp out customize to your heart's content with. Among the numerous Tactical Rail Accessories include a "laser" sight, flip-up iron sights, the NERF version of a grenade launcher, barrel extensions, and for some blasters, interchangeable removable stocks. On top of that, NERF also provides other nifty accessories like the 35 dart drum magazine (for the auto-shotgun Raider), a clamp that allows you to attach two magazines together for a quick-flip reload, and a tripod (for the belt-fed Vulcan). The Recon CS-6 in particular deserves special mention, as it comes with a red-light sight, a detachable stock with space to hold a spare magazine, and a barrel extension with above- and below-barrel tactical rails, an extremely generous helping of tacticool just like a real SOPMOD kit!
    • Many NERF blasters add new toys to the mix: the Spectre revolver comes with a barrel extension made up to resemble a silencer as well as a detachable folding stock, the Alpha Trooper semi-auto shotgun brings with it the 18-dart drum magazine, and the Stampede full-auto assault rifle comes with no less than 3 18-dart (non-drum) magazines, a Tac-rail-mounted ballistic shield, and a foldable detachable bipod stand. On top of that, Tactical Vests and transparent-orange magazines are now available for all you tacticool needs.
    • For even more modgasmic action, the Super Soaker water blasters and the Vortex disc blasters from one toyline have been made with full compatibility with Nerf N-Strike accessories.
    • The 2015-2016 MODULOUS Blaster toyline inherits the N-Strike lineup's propensity for blaster accessories and includes modernized versions of several classic ones like the Longshot's barrel extension/holdout pistol mashup, the detachable stocks with magazine holders, a variety of scopes, and so on.
  • Megatron's original incarnation was a "The Man From Uncle" Walther P38, with an additional barrel extension, scope (which became his fusion cannon) and stock. Megatron's stock was a bit chunkier than on the U.N.C.L.E. Special, though, as it also transformed into a stand for the extension, which became a separate cannon, though this feature was never used in the cartoon or comics.
    • The removable accessories were duplicated on the miniature Megatron guns that came with the original Masterpiece Edition Optimus Prime, and the later Masterpiece Soundwave. The Prime version retains the chunky stock from the original Megatron toy, while the Soundwave version has a cylindrical stock based on the original U.N.C.L.E. Special.
    • Unlike the larger-scale MP-5 Megatron, whose only gun accessory was the scope/fusion cannon, TakaraTomy's upcoming MP-36 Megatron is set to include the barrel extenson and stock as well. Even though the prototype images show a cylindrical stock, it can still transform into a stand for the barrel extension to form a gun emplacement like the original G1 toy.

    Video Games 
  • GoldenEye (1997) popularized the idea of a rifle with an adjustable scope.
    • GoldenEye Wii adds an array of Modern Warfare-esque gun add-ons, like underbarrel grenade launchers, reflex sights, ACOG scopes, and more.
  • Perfect Dark had a variety of interesting and odd weapon add-ons, from the relatively normal (the Falcon 2 had a laser module and optional sight or silencer) to the dangerous (the Dragon's internal proximity mine can't be popular with troops when it goes wrong) to the awesome (the Superdragon's underbarrel repeating grenade launcher) to the downright weird (the self-aiming system in the CMP-150).
  • Parasite Eve 2 had an unusually comprehensive system of Weapon Attachments... some of them was pure boosters, like a bigger magazine for your P08, but other weapons - most noteably the Assault Rifle - had a huge selection of possible attachments. You could mount an underslung Grenade Launcher, sure - but you could also mount an underslung Flamethrower, or an underslung High-Voltage Taser, or an underslung Laser... which was not, I might add, for targeting.
  • Resonance of Fate took weapon-attachments Up to Eleven - Not only can you mount all your weapons with bigger magazines, various scopes and barrel-extensions, but higher-level extensions have, themselves, ports for FURTHER extensions. Towards the end of the game, you'll find yourself wielding an Escher-ish handgun with 8-9 scopes stacked on top of one another, 12 barrels pointing in various directions, 2-3 handles for added stability, and a magazine longer than the gun itself. Assuming you don't go whole-hog with a huge Drum Magazine, but that cuts down on the number of handles and barrels you can attach.
    • Thankfully the attachments don't affect the in-game models, which have a single stock appearance, so you won't have the misfortune of looking upon your self-created abomination in battle.
  • Deus Ex's weapon mods, which consisted of silencers, recoil suppressors, range extenders, laser sights...
    • Deus Ex: Human Revolution has a number of upgrades and accessories for weapons, including specialty accessories. The generic upgrade packs can boost ammunition capacity, reload speed, rate of fire, and damage. Generic accessories include silencers and laser-targeting systems. True specialty accessories do crazy things to weapons, like the mod to the 10mm pistol that makes it completely ignore armor (one-shot kill on any headshot, even against Ogres), the mod that allows bullets to curve to find the target for the machine pistol and the combat rifle, and the mod that gives bullets a remote detonation system for the revolver. Annoyingly, any accessories that you know the enemy is using (like the laser targeting system on sniper rifles) is either not on the weapon when you pick it up, or incompatible with the weapon when you get it yourself.
  • In BioShock, you can find "Power to the People" stations which give one of your guns a single upgrade. Examples include: More damage, larger magazines, faster rate of fire, reduced recoil, better range, no damage from your own shots (for the grenade launcher), random elemental effects (particularly in Bioshock 2) and ricocheting shots.
  • Crysis features a weapon modding system where parts can be swapped onto the various mount points of a weapon; if you feel like it, you can put a sniper scope on your shotgun.
  • Garry's Mod has Spy's Customizable Weaponry similar to the Crysis example above, sights can be added along with front attachments such as an M203, and various ammo types such as incendiary. The base pack uses stock weapons from Counter-Strike: Source though you can download Extra Customizable Weaponry to add even more weapons such as revolvers and shotguns (and yes, you can put an ACOG x4 on one of them like the Crysis example). It also averts many tropes such as Short-Range Shotgun and Concealment Equals Cover.
  • Metal Gear Solid 4: Guns of the Patriots features a similar system, with the ability to customize the optics and mounted parts of a number of the ridiculous assortment of weapons.
    • Metal Gear Solid 3: Snake Eater only had silencers as optional parts, but did feature a scene where a young Revolver Ocelot fitted his Single Action Army revolver with a stock. While riding a motorbike, no less. The End's sniper rifle was also modified; a Mosin-Nagant with a metal side-folding stock and pistol grip firing tranquilizer bullets. And of course there's Snake's custom M1911, which he happily burbles about the enhancements to for several minutes.
    • Metal Gear Solid V: The Phantom Pain allows the player to create an unholy variety of frankenguns once you rescue the master gunsmith. It's possible to take the barrel from one rifle and mount it on another, take the scope from yet another rifle and stick a stock from something else to create a unique custom weapon.
  • The Army of Two games make a big point of having a lot of custom weapon options; the second allows you to bash together parts and create unholy frankenguns to your heart's content ("Why yes, my MP5 does have an AK-47 barrel on it").
    • You can also modify your gun camo; golden finishings increase your aggro (read: making enemies notice and attack you more), while proper camo will decrease it.
  • Gears of War is famed for featuring a gun with an underbarrel chainsaw.
  • Black takes this to its logical conclusion, adding parts to guns simply to make them look cooler; the Uzi is a particularly good example, with the actual charging handle immobilized with a RIS rail. So they added a second charging handle on the side.
  • Call of Duty: Modern Warfare 2 features a laundry list of accessories including various scopes and reflex sights, underbarrel grenade launchers and shotguns, and a rather more farfetched portable heartbeat sensor. In multiplayer there's even a special perk to let you take two add-ons instead of one.
    • Modern Warfare 2 also features several prominent problems with the guns shown. The TAR-21, for example, is built and deployed with an integral red dot sight that runs off a power source built into the gun; there are ironsights, but they're backups meant for use if the red dot fails for whatever reason. Taking the Red Dot Sight attachment with the TAR-21 will give you the weapon's proper real-life dot sight system rather than the generic dot sight most other weapons in the game get.
    • The original Modern Warfare prominently features the M4 SOPMOD, mostly used during the SAS mission. SOPMOD is, in fact, a weapon customization kit (SOPMOD stands for Special Operations Peculiar MODification kit) that includes, among other things, a red dot sight, an ACOG scope, an M203 grenade launcher, a suppressor, a laser aiming module, a foregrip, and all kinds of other fun stuff.
    • World at War allowed the player to use rifle grenades with the M1 Garand and the bolt-action rifles; the process shown is actually incorrect, however, since contemporary rifle grenades required the rifle itself to be unloaded and reloaded with special grenade blank rounds.
    • Call of Duty: Black Ops contains much of the above, and introduces an underbarrel flamethrower. Also new to the game is the ability to change the color of the lens or dot in the reflex sights, as well as changing the dot to a circle, a cross, or a skull, heart, nuke symbol, etc. You can also paint your personal emblem onto a gun and engrave your clan tags into the receiver.
      • To their credit, the flamethrower attachment is ridiculously short lived, firing a full tank in about two seconds due to the very small size. However, since most of the stuff used in the game wasn't developed until long after the Vietnam war... well.
      • Black Ops also has a nice fix for submachine guns being used without stocks like they are in Modern Warfare 2 - most guns in that category already have a foregrip attached, so adding the Grip attachment typically makes your character unfold the stock instead.
    • Modern Warfare 3 adds the Hybrid Sight and HAMR Scope, which are both essentially a combination of a red dot sight and ACOG scope. Special mention goes to the version attached to the RSASS in the "Eye of the Storm" mission, which, like the page image, is a sniper scope with a reflex sight attached to it.
    • Call of Duty: Black Ops II, dear God, Black Ops 2. You don't even need to use a perk to add two attachments to your primary. There's even a wildcard that lets you add three attachments. This game loves the customization so much, in fact, that you can even select and customize your weapons in singleplayer.
      • Black Ops 2 also features the hybrid scope, a reflex sight on top of an ACOG scope. Yes, just like the page image. Not to mention plenty of other futuristic attachments, like a "millimeter scanner" that detects enemies through nearby walls, and a "target finder" that actively highlights enemies for you as you aim. Plenty of the returning attachments are also expanded in what they can be attached to - foregrips can go on assault rifles in addition to the SMGs and LMGs from before, said LMGs can take the variable zoom scope formerly exclusive to sniper rifles, etc.
    • Ghosts went a step further by introducing integrated attachments. Most of these were integrated optics or grips but a handful had the integrated silencer, which in Ghosts was extremely powerful due to these weapons not having the same penalties as their non-suppressed counterparts.
    • Advanced Warfare did a similar thing with their weapon variants. Some had better stats, others had integrated attachments. Both Ghosts and AW freed up Create-A-Class points using integrated attachments.
    • If you thought adding three attachments to a single gun was insane, then Black Ops 3 must be overkill. Now you are allowed to have an optic and two other attachments on your gun as standard. If you use the 'Primary Gunfighter' wildcard, you gain an additional attachment to take it up to 4 in total. There are three levels of Primary Gunfighter. If you really wanted to (and there is a camo challenge for it) you can run around with a gun that has an optic and five attachments and no other things in your class; no grenades, no secondary, no perks, just the uber customized firearm and your wits.
  • Battlefield
    • Battlefield 2142 features a number of modular weapon parts, such as a scope stabilizer for snipers and underbarrel shotgun or grenade launcher for assault troops.
    • Battlefield: Bad Company 2 generally has two variants of each weapon in singleplayer; generally it's either the ammunition or the sight that differs. The assault rifles mount underbarrel grenade launchers, too. In Multiplayer you can customize weapons by yourself. Mostly just red dot and ACOG sights, but also cool gadgets like a scope that automatically marks spotted enemies on the minimap (you normally do this yourself - or, on Hardcore, can't) or buckshot rounds for underbarrel grenade launchers.
    • Battlefield 3 refines gun attachments even more. The barrel, scope, and grips can now be customized to your liking.
  • darkSector features a weapon add-on system that allows bonuses to be added to areas like weapon damage or magazine size, as well as weirder options like making the gun fire two bullets at once on each trigger pull or coating bullets in antiviral gas. Abusing the magazine size mods can potentially allow you to fire four shots out of a double-barrel break-open shotgun before reloading. It also features a rather tacticool AKS-74U with a reflex sight mounted on the forend, the world's first sliding underfolding stock, clipped twin magazine, and a silencer.
    • The Trooper Gun is a rocket launcher with an underbarrel pneumatic Gatling gun. Rawr.
  • From the Wolfenstein series:
    • Return to Castle Wolfenstein had a silenced Sten gun (which did actually exist, but wasn't accurate beyond a couple dozen feet), the Kar 98's scope as a separate pickup, and a very obscure M3 Carbine fitted with a "Snooper Scope," an early active infra-red sight.
    • Wolfenstein had extras for every weapon, from the mundane like carrying more ammo, through the utilitarian like loading the Kar 98 with stripper clips instead of single shots (something it should do anyway), to the extremely silly such as building a magazine-fed Panzerschreck that fired homing missiles. Some weren't visible, like shortening the laser gun's charge-up time from one full second to half a second.
    • Wolfenstein: The New Order generally does this for its unlockable Secondary Fire modes for most of the weapons. Starts out relatively mundane, finding a suppressor for the pistol that makes it fire semi-auto rather than three-round bursts, then the other guns get progressively crazier, such as a second magazine for the shotgun that lets it fire a different type of shell, a rotary-drum rocket launcher under the assault rifle, and ending with folding the scope of the AR Marksman aside to let it fire lasers for some reason. The epitome of this, however, is the Laserkraftwerk, an already-bulky laser gun/cutting tool that you can upgrade by finding pickups across several of the levels, almost all of which add something to the gun - shoving a scope on the side that lets it fire multiple beams at once when aiming, replacing the generator with one that lets it recharge to full on its own, placing an attachment over the front end to let the beam reflect off of surfaces to hit enemies around corners... It's worth noting that with these upgrades, the Laserkraftwerk goes from a gimmicky tool to the BFG of the game, able to kill even an Übersoldat in a single shot if you're lucky (albeit at the cost of almost all its charge).
  • Resident Evil 4 featured a stat-based gun upgrade system, but some weapon also had add-ons; the Mauser C96 and Steyr TMP had optional stocks, while the rifles and mine thrower had optional sights; the rifles could mount a fixed scope, adjustable scope, or a thermal sight. In addition, almost all the weapons in both 4 and 5 feature a laser sight to provide a third-person aiming point for the player without using a crosshair.
    • The Hydra in 5 adds its laser module simply by duct taping it right to the underside of its triple barrels.
  • The original Killzone had secondary fire modes for the weapons; the ISA rifle had an underbarrel grenade launcher, the Helghast rifle an underbarrel shotgun, and so on. These were removed in the sequel, though the ISA rifle gets a usable EOTech reflex sight instead.
  • In Turok: Evolution, most of the weapons have additional upgrade parts. These include a folding stock, barrel and scope to turn the pistol into a Sniper Pistol, a unit that lets the shotgun fire multiple shells at once, and, ridiculously, an upgrade that lets the wussy flechette gun unfold itself into a triple minigun.
  • The S.T.A.L.K.E.R. games feature various weapon modding systems; in the first there were add-on parts (grenade launchers, silencers and scopes); the second included a stat-based system but retained the physical upgrade parts as well.
  • In Dirge of Cerberus, Vincent is allowed to construct three guns from any combination of parts; there are three main "frames" (respectively being ridiculous mutant triple-barrel versions of a revolver, submachine gun and rifle), each of which can be fitted with a short, medium or long barrel (bearing in mind this is Vince, so the long barrel is four goddamn feet long and even the medium barrel makes Cerberus as big as Vince's leg), a scope or magic booster in one slot, an "option" in another (stat boost) and an "accessory" in a third (a Materia, generally). It's a lot less flexible than it sounds.
  • Halo:
    • The games feature a sniper rifle with a digital night-vision-capable scope and the infamous scoped pistol, but the basic Assault Rifle has something much stranger; a built-in compass that in Halo: Combat Evolved pointed to the gas giant that the Ringworld orbited. Precisely why the rifle had such a feature is not really clear: A Watsonian interpretation might be that the weapon had been designed by Earth-based humans and the built-in compass was intended to provide the same navigational aid that any magnetic compass would; tn this scenario, the compass pointing to the nearby planet's magnetic field is an immersive bit of fluff that drives home what an inhospitably alien place the characters have found themselves stranded: a world that plays by its own rules and defies their familiar tools. A Doylist interpretation might be that the compass is a holdover from earlier in Halo's development when it was supposed to be less linear/episodic in its levels and more of an open-world experience; the compass may have been useful to players' navigation in the context of the original game design.
    • The Assault Rifle also displays the number of shots it had remaining, which would have been more useful if your HUD didn't also show that. In Combat Evolved, it and the shotgun also had a built in flashlightnote .
    • The Battle Rifle and Designated Marksman's Rifle both also have ammo counters, in addition to 2x scopes.
    • Halo 3: ODST's SMG has both a scope and a silencer.
    • Halo 5: Guardians's Warzone mode allows you to add all sorts of attachments to your basic guns; digital projection sights, scopes, silencers, energy bayonets, etc.
  • Quake IV featured a primary assault rifle fitted with a scope and tactical light; in addition, many weapons were modified by NPCs during the course of the campaign, with mods including a magazine feed for the shotgun instead of reloading one shell at a time, a scope and lock-on for the nailgun, Chain Lightning for the Lightning Gun, and so on.
  • Far Cry featured several weapons with scopes, a G36 with a scope and underbarrel grenade launcher, and the OICW carbine-automatic grenade launcher combo. Far Cry 3 and 4 allow for weapons to be modified with various accessories, most commonly sights of some kind but with suppressors and extended magazines also available for a lot of weapons.
  • In Soldier of Fortune 2, it's possible to select accessories for some weapons.
  • Dante's guns Ebony and Ivory in Devil May Cry are heavily customized Colt M1911 pistols with massive top-ported compensators, wood grips, customised slides with side exterior ejectors, and extended magazines with slam pads. The rifle "Spiral" in the third game is a customized Lahti L-39 anti-tank rifle with a shortened barrel, overhead grip and added wooden handguard instead of the usual ski-equipped bipod.
  • One of the preorder DLC bonuses in Just Cause 2 is a custom revolver that actually mounts an underbarrel grenade launcher (which cannot be used, unfortunately).
  • The F.E.A.R. series has a few tacticool fictional guns, including one that's a full-auto Heckler & Koch SL8 with M14-style sights and a comparatively tiny 45-round C-Mag, and a submachine gun with a purely cosmetic flashlight (nobody uses it, not even the Player Character) on the front grip, which is modeled specifically to hold said light. But the crowning glory is FEAR 2's pistol, however; in the standard Black tradition, this has a big accessory rail mount covering the whole front of the gun, with top, side and lower mount points. What's on it, you ask? A second set of iron sights and nothing else.
  • Fallout: New Vegas introduces weapon attachments like scopes or extended magazines, although Fallout 2 had a simpler version of the game mechanic. The Gun Runners Arsenal DLC introduces special versions of certain weapons with even more accessories.
  • Fallout 4 takes this trope and runs with it, allowing characters to extensively mod their weapons for more damage, more accuracy, more range, and the like. There's even a perk dedicated to creating gun mods, which is appropriately called "Gun Nut".
  • Borderlands features a modular system that is used to procedurally create weapons; there are millions of possible combinations, though with the exception of a few unique guns they were mostly cases of improvements, but then their idea of more does include rounds that cause enemies to be electrocuted, burn, be melted by acid or just outright explode.
    • In the sequel, Dahl sniper rifle scopes, just like the page image, have a reflex scope attached. Much like common sense would indicate however, it's useless.
    • Guns in 2 and the Pre-Sequel can have components that are actually called "accessories". These include bayonets, laser sights, and even additional barrels, and are recognisable - sometimes - by applying a prefix (a Torgue "Bad Touch" weapon probably has a bayonet, for example).
  • Mass Effect has a VERY extensive system. All weapons are modular and collapsible for easier transport. Additionally, all but one can accommodate one or two "mods": small packages that contain stuff like extra heatsinks, stronger accelerator rails, stronger scopes for sniper rifles, etc. Even bullets have mods like polonium rounds (poisons target and stops regeneration), incendiary rounds, EXPLOSIVE rounds... Mods can be installed and removed in no time (literally, since the game is paused on the inventory screen), even during battle. The right amount of mods and upgrades on guns will make them seem like entirely different weapons. For example, take a Volkov sniper rifle, and put two Scram Rail X mods on it along with an Explosive Rounds X mod. It now overheats after every shot, giving it a very slow firing rate, but it can take out multiple enemies with one hit, and does enormous damage to boss-class enemies, making it more like a rocket launcher than a sniper rifle. Similarly, mounting an Inferno Rounds X mod along with a few heatsink upgrades on a Thunder assault rifle will give it huge damage and capacity, but also somewhat punishing recoil- much like a light machine gun.
    • Mass Effect 3 re-adds gun accessories. The mod system is not quite as complex as Mass Effect's, but a hell of a lot more convenient, since you don't have to keep track of hundreds of individual accessories (after you find the accessory once, you're given unlimited copies for all guns of that class). Mods are now assorted by strength from levels I-V rather than I-X now. Things like scopes, bayonets, and piercing mods can be put on the guns in addition to Mass Effect style upgrades the give a flat upgrade to damage or capacity, and you can still equip your guns with various types of specialized ammo. Multiplayer adds another layer to the mod system by allowing you to apply four mods to your guns (two accessories, a specialized ammo type, and a one-use upgrade that enhances damage, decreases recoil, or increases only headshot damage) rather than three.
  • Medal of Honor: Airborne features an experience system where unlocks in the form of weapon modifications are earned by using the weapon in question; these include such addons as scopes, bayonets and extended magazines.
  • The Jagged Alliance series has these, especially Jagged Alliance 2's 1.13 mod, where almost every accessory listed above is present in the game.
    • One thing that's NOT listed above: Kobra reflex sight that can only be mounted on Russian side rails and fits on Russian assault rifles in game. Also, caliber/length changing barrels, such as AR-15 upper receivers for FN 5.7mm rounds, and EBR stocks for M14 rifles are categorized as "accessories."
    • More modern firearms with Picatinny rails can accept a wider variety of accessories compared to older WW2/Vietnam War era guns. The EBR stock does exactly that to the M14.
    • Also, while accessories make hitting stuff easier, they do add to the weight of the gun, and mercenaries with weak strength suffer from the weight of the gun by moving slower and getting less shots per turn. Gets quite serious when a fully modified 5.56mm assault rifle can weigh as much as 15 pounds (7 kilograms) with a C-Mag attached.
  • Brink includes the ability to customize most of the weapons in the game with muzzle breaks, silencers, scopes (both ACOG-like tubes and red dots), extended/drum magazines, and more.
  • 7.62 High Calibre features a heaping helping of gun accessories. Guns are limited in what they can mount both based on their design, and the accessories themselves: some accessories (especially scopes) are designed to fit specific guns, so trying to mount a PSO scope for an SVD sniper rifle on to your M14 won't work. The most versatile accessories are rail-mounted, but they are also invariably more expensive. You can trick out your gun with a silencer, a tactical flashlight, a laser-sight, a scope (true sniper, red dot, or ACOG), an underbarrel attachment like the Masterkey shotgun or grenade launcher, a bipod, and a bayonet. Whether or not you want all that (hint: you don't) is up to you.
  • For a post apocalyptic Scavenger World series, the Metro 2033 series sure takes the trope and runs with it. For example, just the revolver can actually be modified with a scope, extended barrel, stock and silencer, effectively giving you a silenced sniper rifle as your sidearm. The sequel, Metro: Last Light, takes it one step further by adding a wide gamut of scopes, sights, stocks and barrel extensions to almost every gun in the game, and giving you the option to customize your piece however you like at the shops (for a price, of course).
  • Introduced to Saints Row: The Third are upgrades for weapons that change how they work, most commonly adding explosive, incendiary, or armor-piercing bullets at the highest level. A few guns also mount other accessories such as scopes and flashlights.
  • Ghost Recon: Future Soldier takes this to a ridiculous new degree; muzzle mounts, barrel lengths, optics and scopes, side rail mounts like LAMs and heartbeat sensors, underslung mounts like grenade launchers and foregrips or even bipods, stocks, trigger types, gas systems, magazines and ammunition, and colors can all be modified as you see fit with the Gunsmith feature. Using it with Kinect even makes you feel like you're Tony Stark to a degree with the motion-based control system used with the mode.
  • Blacklight Retribution uses a modular system for its weapons. Players can build a gun from the ground up from the basic receiver (the actual firing part of the weapon) using barrels, muzzles, stocks, magazines and scopes, all of which have a small numerical effect on its performance. They can also paint the gun a variety of colors, if they pay for it.
  • While Syndicate 2012 does not have customization in single player, it is not lacking in tacti-cool weapon attachments. Several guns mount multiple sights, at odd angles - one of the assault rifles has the semi-automatic mode using an ACOG style scope, with the full-auto mode using a red-dot sight mounted at a 45 degree angle in front of the ACOG; your character holds the gun sideways when using it.
  • The first two ARMA games would have several variations of the same base gun with different preset accessory combinations—in particular the M4A1 has ten different versions. The third game gets rid of the presets, and lets you select weapon mods to include individually. And, yes, once again you can put a sniper scope with a reflex sight on your gun.
  • Splinter Cell: Chaos Theory gave you several choices of underslung secondary weapon to attach to your standard silenced rifle (collectively dubbed the "Modular Assault Weapon System): the "stealth" option, as in previous games, launches your choice of less-than-lethal projectiles, sticky cameras and distraction devices. Alternatively you can go for the less subtle approach — the "Assault" options are a shotgun attachment and a high-powered Sniper Rifle attachment.
  • Unturned has three possible slots for gun accessories: the barrel, sights, and a tactical mounting. The barrel accessories are a barrel extension to increase. Sights obviously are for aiming and range from iron sights to x20 zoom scopes. The tactical slot is unavailable to pistols but has various options—including different grips to reduce recoil, a laser sight to assist aiming, and a bayonet for quick defense.
  • Grand Theft Auto V and its online mode now feature modifiable weapons. Most offer a better grip (marginal range improvement), larger magazines, scopes, flashlights, and/or suppressors. (As well as paint jobs, for those who insist on having a pink M249.)
  • Metal Gear Solid V: The Phantom Pain features an extensive gun customization aspect. By developing different types of the same class of weapons, it becomes possible to modify many different aspects of any given gun, from the practical (barrel length and stocks) to the cosmetic (color and camo type) to the absurd (want a 8x adjustable range finder on your shotgun? Go for it!)
  • Bowguns in Monster Hunter can be upgraded with different accessories, depending on type. Light Bowguns have the option of adding a silencer that not only reduces aggro drawn but also lowers your weapon's recoil. Heavy Bowguns can opt for a shield attachement instead. Both Bowgun types can also be outfitted with a Long Barrel / Power Barrel instead that simply pumps up the damage.
  • XCOM 2 allows you to research ADVENT modular weapons technology, which will eventually allow you to attach a variety of accessories to your operative's weapons (upgraded weapons can have more accessories attached). These include:
    • Stocks that make your operatives just barely accurate enough to do chip damage even if they miss.
    • Scopes or Laser Sights that will respectively improve accuracy and critical hit rate.
    • Extended magazines and Auto-loaders. The first increases the amount of ammo pips available for you to use per reload, the second gives you a number of free-action reloads per mission.
    • Repeaters, which make your weapons capable of randomly killing aliens instantly regardless of their health.
    • Hair-Triggers, which make some of the shots you take randomly become free actions.
  • Contagion has a good number of gun calibers, most of which have one gun that has a mounted tactical light, and one that doesn't. The ones with lights are always better unless you take the PvP route, as the pocket light is often a poor alternative that takes up an inventory slot and doesn't always point in the direction you want it to while you aim.
  • Doom (2016) includes several "weapon mods" that take the form of anything from a low-tech optical scope on the Heavy Assault Rifle, to a targeting system on a rocket launcher that allows you to fire a barrage of homing projectiles at multiple targets, to a barrel replacement on the Chain Gun that transforms to give it triple the barrels and a commensurate increase in firepower. All of these function as the weapons' Alternate Fire and most have two that you can swap out on the fly once you unlock them.
  • Ratchet & Clank almost always features some kind of mod system that adds extra effects like covering the target in acid or releasing electric shocks to nearby enemies. The granularity of the mod systems vary from game to game, but they have undeniable effects on the targets.
    • Ratchet & Clank Future: A Crack In Time manages to combine this trope with IKEA Weaponry with the Constructo Weapons, where the trigger, chamber and upgrade can be completely swapped out, giving effects like beam shots for the Pistol, changing the shape of the explosion for the Bomb Glove or the ammo type of the Shotgun.
  • PAYDAY 2, with its gigantic array of weapons, has a fleshed-out weapon customization feature to go alongside it. Every single weapon has at least a couple bits and bobs that can be added or replaced, be it ammunition, grips, sights, stocks, lasers, flashlights, laser-flashlight combination modules, or skins. Most accessories must be found from an end-of-round loot drop before they can be purchased and equipped. Some are DLC-exclusive, and require either a loot drop or unlocking a specific achievement. Weapon skins can only be found in safes, but can also be bought on the Steam Market.
  • Serious Sam 3: BFE
    • The shotgun has a side saddle. It's there just for looks, as the shotgun is magazine-fed, and indeed Sam never puts shells in it.
    • The assault rifle has a vertical grip, a flashlight that Sam never uses, and a reflex sight. The last one is important for the gun: using it zooms in the view a bit and completely removes bullet spread, drastically increasing the rifle's effective range.
    • The Devastator gets a scope if the player has the Deluxe edition.

  • The AR 15 Builder is similar, though it's actually a custom order system for a real gun manufacturer rather than a toy.
  • This site lets you play around with various accessories for a pistol.
  • According to this IMMD entry, a kid managed to make an improvised sight.
  • FPS Russia will typically display a variety of Cool Guns on his show with the occasional bit of Abnormal Ammo, but occasionally the main feature is an accessory/conversion kit. Past episodes have included kits to turn rifles into smaller, lighter rifles (usually cheap, plasticy garbage); kits to turn pistols into bigger, meaner pistols; and kits to turn rifles (and in one case a shotgun) into a bullpup configuration. Individual attachments like scopes are rare, though one episode about a tactical shotgun featured a variety of SWAT-style attachments.
  • Iraqveteran8888 often display new accessories they have discovered and reviews; Chad often mentions how he likes to suppress his more modern weapons; and in the Tactical vs Practical episode, Barry mentions his closet full of stuff he'd bought for guns over the years that he wasn't going to put on a gun ever again. They don't set out to say that you can't have this joke if you want to, but that was intended to be comedy and they will not recommend doing that. Still, they got so many views they felt a need to go out and make a video of them shooting it (A likely story!). They have done the same to a Ruger 10/22, and posted an episode of their popular "5 Guns" series on the 5 most customisable guns.

  • Moral Orel, in the "Nature" two-parter, Clay has a cup holder for his shot glass attached to his hunting rifle.

     Real Life 
  • In real life, the obsession with accessories often leads to terms like "geardo" and especially "tacticool" being thrown around. And debates still rage on and on as to which accessories are acceptable, but for the most part, if you slap crap on that you're most likely not going to use unless you're a SWAT member or Black Op and aren't intent on murdering anyone but poor practice targets, you'll get laughed at/flamed. Especially if you've stacked on so many accessories it's hard to find the gun underneath them.
    • Some take it to extremes for kicks, such as the Tacticool Mosin-Nagant below. Yes.
  • 37mm flare launchers are popular as rifle accessories; not because they're even remotely useful, but because it looks like you're a badass with a proper 40mm underbarrel grenade launcher. At least that's the theory, since it's titanically unlikely anyone who actually owned such a thing would attach it to his range toy.
    • In movies, these often play the part of real underbarrel launchers, since they're cheaper, easier to get hold of, and don't require large numbers of murderously expensive destructive device permits.
  • The domestic version of Germany's G36 assault rifle has a dual scope, with one of the eyepieces being a reflex sight and the other a magnifying scope.
  • Combination weapons such as the XM29 OICW and Daewoo K11, make it a little hard to determine which weapon is the main and which is the accessory. The OICW gains bonus points here, since, despite weighing 18 pounds loaded (as much as two and a half loaded M4 carbines), it still had provision for mounting a bayonet.
    • That's not the most absurd case of a bayonet lug, though; in World War II there were Japanese machine guns with bayonets. The Imperial Japanese Army was rather blade-obsessed; about the only thing they didn't stick bayonets on were pistols, and that's probably simply because they didn't have the time to get away with it.
  • This Pimped Out Pistol is a particularly good example, given that the pistol would be impossible to load. Due to the way that the action of the pistol works, when the slide is pulled back to chamber a round, the barrel, and hence the silencer, tilt upwards by a few degrees. This is clearly impossible with the scope flush against the silencer, so to load (and to fire) the pistol one of them would have to be removed.
  • The Muzzelite bullpup stock is an accessory stock that you actually shove the entire gun inside; after throwing in a compatible Ruger or Marlin action, you can pretend you have a proper bullpup rifle. One made of cheap plastic with a hideous trigger pull, but that's tacticool for you. These formed the basis of the Morita assault rifles in the Starship Troopers movie and the M590 assault rifles of Space: Above and Beyond. There are a wide variety of other bullpup conversion kits for a wide variety of rifles.
  • Trench warfare gave the world the Periscope Rifle, a way to lean up and fire over a trench without the annoying part where the dastardly Huns blow your head off your shoulders.
    • How could you insert the Periscope Rifle without mentioning the equally goofy Krummlauf Device? Invented by the dastardly Huns for use against the Britischer pigs, Amerikaners,
  • Perhaps the silliest are accessories larger than the actual gun. Such as the Cornershot, a pistol (and more recently carbine and single-shot grenade launcher) accessory the size of a full-size rifle that includes a camera and mount and allows the mounted gun to be sighted and fired around corners. Cat accessory optional. Seriously.
    • Not so silly. Urban warfare is becoming increasingly common, and the ability to look around corners and shoot at enemies without exposing yourself to return fire is quite useful. As technology advances cornershot devices will undoubtedly become lighter, more portable, and compatible with even more types of firearms. The cat accessory might seem weird (and, well, it is) but it may also be useful for camouflaging the weapon. If the enemy sees a gun barrel poke around a corner they know you're there even if they can't hit you. But if they see what appears to be a cute little kitty cat, they may ignore it until it's too late.
  • You knew this would exist, didn't you?
    • At the other end of the cup holder / gun scale, the Battle Mug features standard accessory rails and thus is actually capable of being fitted with rifle accessories (it actually comes with an M4 carry handle/rear sight as its grip), allowing you to at last have a cold one with a reflex sight and taclight.
  • The Tacticool Mosin-Nagant. What has science dooone?
    • Bear in mind that under US law, making these alterations would be quite illegal without registering in advance with the ATF, since the barrel is well below the 16-inch limit.
  • There's a kit that turns a Browning M1919 into a "modern" SAW-style weapon (translation: it looks like it's from the 90s rather than the 30s, has rail sights and a foregrip). This is presumably aimed at the tiny handful of countries that still have them in reserve military service, as why anyone would want to visit such horrors on one of the relatively small number of transferrable M1919s is hard to imagine.
  • The Swedish Army tactical manual outright states that when you load a magazine into your weapon before heading into a firefight, it should have another one duct-taped to it. It also instructs you on how to do it properly.
    • As ridiculous as the idea sounds, some weapons (the SIG SG 550 for example) have magazines designed to be clipped together, and Heckler and Koch even makes a specific accessory that holds two MP5 magazines together (they're about an inch apart) to facilitate speedy reloading. The practice is depreciated for calibres of 7.62x39mm and larger, however, as it adds enough weight to play merry hell with the weapon's balance.note 
      • In the case of the SG 550, its clear-plastic magazines have tabs on both sides for clipping on additional magazines. This means that there's no theoretical limit to just how many you can clip together; instead the user can decide for himself when he's reached the level of absurdity. Actual Swiss Army practice is to clip three mags together. This is also true for the German Bundeswehr; G36 magazines can be clipped together in the same manner, but here the idea is to only do it when taking a defence position where it's possible to put the gun on a rest (like sandbags), otherwise the aforementioned aim problems would occur again.
    • This is called "Jungle Style" clipping, which has its roots in World War II with the M1 Carbine. Troopers would tape two magazines together to facilitate faster reloading.
    • While the idea may sound ridiculous for westerners, the Russian military has been using iconic blue duct tape to tape mags together for a long time. In Russia it's called 'Valet welding'.
  • Think underbarrel grenade launcher is cool? Try underbarrel shotgun. And yes, they actually use this in real life.
    • One of the uses for such an add-on? Shooting out the locks on doors. Or, more accurately, shooting the door off of the lock, allowing it to be easily kicked open. Hence the first such add-on, a cut-down Remington 870 shotgun attached to a mounting system to fit under the barrel of the M16 or M4, was called the "Masterkey".
  • The Israeli Galil assault rifle has two accessories built into the bipod. The first is a wirecutter. The second is a bottle opener. The second may sound strange, but among the civilian reservists serving in the IDF a wide-spread habit had them popping the tops off of soda bottles with the rifle's magazines, which damaged them.
  • While it may be for Airsoft, Evike posted a video on their YouTube channel of this monstrosity termed the Optic Thunder M4. It serves as an extreme example of what not to do while deciding on attachments for Airsoft guns you plan to use.
  • Latvian Armed Forces have their G36KV3 assault rifles fitted with Aimpoint sights by default. If needed there are night vision attachments to go on either the helmet or on the rifle, tactical flashlights, foregrips, laser sights... Long story short, there're five (four if you have a 40mm grenade launcher) Picatinny rails of varied length on this rifle, and they are all used for something.
  • The Colt Canada C7A2 is an insanely customizable weapon. The list of accessories that will fit this beast is a mile long: It can take any accessory made for the M16/M4 family of rifles, a number of accessories for completely different kinds of weapons, as well as an onslaught of accessories made specifically for it.
