Blasters can be classified by their firing mechanisms.
Direct Plunger: The most common classic firing mechanism, and also the most basic design. Very popular with modders due to the efficient and powerful design modern Nerf Blasters use.
Indirect Plunger: A plunger type popularized by a majority of N-Strike blasters, the indirect Plunger is somewhat less efficient due to deadspace inside the plunger chamber, but takes considerably less space.
Also referred to in the fan community as Reverse Plunger.
Air Pressure Chamber: A classic blaster mechanism adapted from water blasters like the Super Soaker family, the few Nerf blasters that use air pressure chambers are pump-action.
Electrical Flywheels: With the N-Strike Barricade, Nerf reintroduced flywheel blasters. Early designs were unreliable due to the potential for unequal torque from horizontal flywheels causing loss of accuracy, something the Barricade eliminated with its vertical flywheels.
Electrical Plunger: The Stampede, Vulcan, and Swarmfire possess powerful electrically-driven plungers that can fire in full-auto.
One of the earliest Nerf blaster types, Ball Blasters tend towards having a fixed, internalized feed chamber which can be loaded with multiple foam balls. Several notable blasters include the Atom Blaster, the Cyclotron, and the Pulsator.
Early Dart Blasters
A later adaptation, the early dart blasters tended towards bigger darts and muzzle- or chamber-fed mechanisms, usually powered by springs, although variant blasters that used flywheels or air pressure chambers also exist.
There were several major families of blasters, the Air Tech series, the Action Blasters, and the Airjet Power series.
These are their most successful products, with several categories of darts by size. The Micro Darts survived into later N-strike and Dart Tag blaster lines, while an upcoming rifle blaster might potentially revive the Mega Dart size class.
Big Bad Bow: A Nerf "longbow" design blaster that actually performs more like a crossbow. Uses foam arrow ammo instead of darts.
Rapid Fire AS-20: A rotary-barrel blaster that evokes a handheld Gatling Gun, this blaster utilizes a pump-action air pressure system to fire its darts. A pressure gauge on the side tells you how much pressure you have pumped into the bladder.
Magstrike: An Air System blaster that has its own unique clips/magazines, the Magstrike can discharge its entire ammo load in a single burst. Until the advent of the Raider and Alpha Trooper, this blaster was immensely popular in Humans VS Zombies.
Hornet: An Air System blaster with a vaguely similar design to the Magstrike sans the clip/magazine structure.
Nitefinder EX-1: Using Micro Darts, with a powerful single-shot muzzle feed, this is one of the most celebrated classic blasters that has endured for years, being reintroduced with the N-strike series and then modernized for the Elite lineup.
Titan: A rocket launcher blaster, the Titan shoots massive foam rockets. Especially noted for being one of the first blasters to feature Tactical Rails, a RIS-style rail system.
Maverick REV-6: the Revolver Handcannon of the Nerf family, and the other most-reproduced classic blaster that also featured in the N-Strike lineup. Most infamous for quality control issues with the cylinder advancing mechanism.
Firefly REV-8: a revolver with glow-in-the-dark darts and integrated LED that simulated muzzle flashes, the Firefly's Power Glow was replicated in future blasters and the blaster itself enjoyed a time being re-released as a N-Strike blaster.
Early Disc Blasters
One of the NERF experiments, the earliest disc blasters could not match the performance of their dart blasters.
N-Strike and the rise of streamlines
In the 2000's, the N-Strike series emerged. while several older blasters made a comeback with the N-Strike branding and colours, the new blasters that were introduced mostly had a more realistic design that resembled real firearms and had actual magazines and Gun Accessories.
Streamline micro darts are the name of the game with many of these new blasters, with their small, narrow rubber heads making them able to fit into the new Clip System Magazines.
Blazing Bow: A seeming replacement for the Big Bad Bow, the Blazing Bow has a fiery paintjob and also uses the same foam arrow ammunition. It was marketed under the N-Strike branding.
Reflex EX-1: Also known as the Eliminator, this little Nerf Derringer uses a reverse plunger mechanism and was the smallest blaster until the Secret Strike and the Jolt. Also the smallest blaster to use a reverse plunger mechanism.
Elements EX-6: Essentially a Nitefinder with more dart-holder slots under-muzzle, the Elements blaster comes with a Red Light Sight and a Telescopic Sight.
Scout EX-3: A blaster that was originally designed to be used as an attachment to the Titan AS-V1 as part of the Unity Power System, it is a sleek pistol that is somewhat related to the Nitefinder in design and is modeled very much like a real handgun.
Recon CS-6: The mainline blaster of N-Strike and the most prominent, the Recon is a modular semi-automatic/machine pistol with a slide, and features the Clip System magazine and customizable Tactical Rail system. It also commonly ships with a barrel extension with more Tac rails, a detachable stock, and a red-light sight, which allows you to customize it like a SOPMOD SMG.
Longshot CS-6: The first Sniper Rifle of the N-Strike family, the Longshot was a powerful blaster with a direct plunger system and a barrel extension that could be used separately as a holdout single-shot pistol.
Secret Strike AS-1: A genuinely compact micro-blaster, the Secret Strike utilizes a gas pressure chamber instead of a spring-driven plunger, making it more discreet and stealthy than any other N-strike blaster.
Longstrike CS-6: The second Sniper Rifle, the Longstrike has some design elements taken from several famous rifles including the Accuracy International Artic Warfare. It has a stock that is usually not removeable once attached, and a detachable barrel extension, and its fixed shoulder stock can hold 2 extra 6-dart Clip System magazines.
Vulcan EBF-25: THE belt-fed man-portable Nerf Machine Gun, the Vulcan boasts a electrically-powered fire rate just above 3 darts perf second, as well as the ability to fire single shots manually. Produces a distressingly realistically loud clatter from the bolt mechanism when fired on full auto.
Raider CS-35: A pump-action semi-auto shotgun, the Raider introduces the massive 35-dart drum magazine as well as semi-automatic Slam Fire.
Deploy CS-6: A collapsible pump-action shotgun-like blaster which folds up for easier carrying/concealment.
Spectre REV-5: An evolution of the revolver form factor, the Spectre sports a greatly-improved baseline performance over the Maverick, as well as superior reliability. They also introduced the detachable Folding Stock.
Barrel Break IX-2: modeled after a double-barreled shotgun, the Barrel Break evokes the Lupara sawn-off shotgun. One of the few rare breech-loading blasters that do not use magazines.
Alpha Trooper CS-18: A slimmer cousin to the Raider, the Alpha Trooper features the same Slam Fire mechanism and packs an 18-dart drum magazine. It is very popular with players of Humans VS Zombies.
Stampede ECS: Sitting squarely between the Vulcan and the Recon in terms of size/firepower, the Stampede is the first true carbine/assault rifle of the Nerf Blasters. Featuring an always-electrically-powered firing mechanism, the Stampede ships with a forward grip that can expand into a bipod, three 18-dart extended magazines, and a clip-on Ballistic Shield. Amusingly, it can even malfunction in a manner evocative of gas-piston carbines like the Kalashnikov family!
Jolt EX-1: AKA the Noisy Cricket Gun, the Jolt is the smallest N-Strike blaster, and packs a deceptive amount of power in its direct plunger mechanism.
Barricade REV-10: A fully electrical flywheel revolver that can take N-Strike detachable stocks. One of the first blasters to really herald the age of Guns Akimbo blaster play in Nerf, it produces an unmistakeable ominous roar when its flywheels are powered up and spinning.
Rayven CS-18: A fully electrical flywheel bullpup blaster design that takes cues from the famous real-world p90 SMG, the Rayven comes with a 18-dart magazine that can light up and charge "Firefly tech" luminous darts. Its flywheel motors in stock produce a different whine from the Barricades.
Switch Shot EX-1: A special variant pistol blaster which was provided with the Nerf N-Strike official video game on the Wii. A fully-functional pistol blaster in the same vein as the Scout and Nitefinder, you can flip the sighted muzzle guard down and remove the barrel and plunger block assembly to make room for a Wiimote, allowing you to use the blaster's receiver and grip as a Wiimote gun-controller shell. It comes with a red lensed sight that lets you see special hidden messages in the game.
Dart Tag Blasters are the main non-N-Strike blaster family of Nerf dart blasters. A number of them lack Tactical Rails, and they are all designed to use the velcro-headed Tagger Darts. Older Dart Tag blasters are red or green with orange highlights, while the later post-2011 models are all a darker yellow over grey, with bright orange muzzles.
Strikefire: a blaster notable for having inverted Tactical Rails, it can be mounted on other blasters.
Furyfire: a pump-action 10-shooter Revolver/Shotgun hybrid blaster, the Furyfire is significantly longer than a Maverick and more reliable.
Sharp Shot: A 2012 Dart Tag blaster that is similar to the Scout IX-3.
Speedload 6: A 2012 Blaster design with an integrated banana magazine and a slot feed. Somewhat like a Recon, only with Slam Fire.
Quick 16: A 2012 Blaster design like the Speedload 6, this blaster is extremely evocative of the Raider CS-35.
Swarmfire: An electrically-powered full-auto 2012 Blaster with 20 rotating barrels and a sizeable stock.
Speedswarm: Another electrically-powered automatic, this blaster is the pistol or SMG counterpart to the Swarmfire and has 10 barrels.
Snapfire 8: The full-manual double-action 8-shooter revolver cousin of the Swarmfire and Speedswarm, the Snapfire features an adjustable spring for variable power. Its powerful spring mechanism gives it considerable trigger pull distance and resistance versus most other dart blasters.
Vortex Blasters, introduced in 2012, are Nerf's latest attempt at resurrecting the old Disc Blaster designs with improved engineering. Utilizing torsion-spring launching mechanisms instead of the breech-and-plunger designs of a bulk of the N-Strike series, Vortex Blasters ditch the semi-realistic look and instead aim for a sleek futuristic blaster design. The oblong barrels give them a pesudo-raygun design, and their primarily green/black or white/dark grey shells with bright vermillion highlights make them stand out.
Many Vortex Blasters can use the same kind of detachable shoulder stocks as N-Strike blasters, and most of them possess Tactical Rails and can use the same scopes, grips, and tripods/bipods.
Vortex Blasters utilize the XLR (Extra Long Range) Discs as ammunition. These foam discs have a hollow plastic core that helps improve their aerodynamics and keeps them light and durable.
Proton: A single-shooter disc pistol that fills the role of the Nitefinder of the lineup. Small but powerful.
Vigilon: A disc pistol with an integrated magazine with a 5-disc capacity.
Praxis: A pump-action disc blaster that uses magazines. Comes with a detachable shoulder stock and a 10-disc magazine.
Lumitron: Similar to the Praxis but packaged with glow-in-the-dark disks and a battery powered magazine that charges said disks with lights. Not unlike the Rayven's darts and clips.
Nitron: An electrically-powered disc blaster that uses magazines and has an integrated shoulder stock. Comes with an electrically-powered scope and a 20-disc magazine.
Pyragon: A disc blaster that comes with a 40-disc drum magazine and can use detachable stocks. It can be fired both with pump-action and slam-fire.
Diatron: A unique disc pistol that can shoot 2 discs at once, it possesses an integrated drop-down magazine and can load 10 discs. Often compared to the Rough Cut Elite Blaster.
Revonix 360 (Nerf Hub article): A slam-fire disc blaster to be released in the latter half of 2013, with an integrated revolving disc drum magazine that can load 30 disks at once. It sports a pistol-gripped slamfire handle in a fashion similar to the N-Strike Raider and Elite Rampage.
N-Strike Elite is the evolution/successor to the N-Strike lineup that retains the tacticool semirealistic blaster style. Most of the blasters in this lineup are either updates to existing blasters with improved power, or recoloured blasters rebranded and reproduced for modern play. Most Elites are available in a blue/white/black colouration with bright orange muzzles and highlights.
Elite Micro Darts are the official new ammo type for most Elite Blasters, although existing Streamline darts from the N-Strike lineup are still usable. A number of MEGA series Elite blasters use the bigger Elite Mega Dart instead.
Notable Elite blasters:
Retaliator: An updated Recon with Slam Fire that comes with a 12-dart extended magazine and a SOPMOD kit-like selection of Gun Accessories.
Rampage: An updated Raider with a 25-dart drum magazine.
Hail-fire: An all-new Electrically-Powered Flywheel semi-automatic blaster, the Hailfire sports 8 Magazine slots arranged in a rotary carousel, allowing you to lock on a lot of ammunition for extended battles. An Advance Handle atop the blaster helps you with easier handling of the blaster's sizeable mass and lets you advance the carousel as you deplete your magazines. The Hailfire's engine and flywheel have been examined by modders and pronounced more reliable and durable than other standard flywheel blasters.
Stockade: An updated Barricade electrical semi-auto revolver with a detachable stock that can hold 10 more darts.
Strongarm REV-6: A revolver with several improvements in its design, it also sports Slam Fire. Unlike the Spectre or Maverick, it advances its cylinder after each shot, and has a different seal mechanism more in line with the Dart Tag Swarmfire's revolving turret assembly. Has been received very well as a proper successor to the Maverick with the worst of the old revolver's flaws addressed and fixed.
Firestrike: An updated Nitefinder with a sleeker design and a separate trigger for the integrated red light sight. The butt of its pistol grip has a spur to let you dual wield this blaster and still be able to prime them between shots effectively.
Stryfe: The OFFICIAL answer to all the Nerf Modders who cut apart their Barricades to modify them for using Clip System magazines, Stryfes are electrically-powered Flywheel semi-auto SMG blasters. Extremely popular with players of Humans VS Zombies, who tend to tape up the magazine sensor to prevent mechanical fault when using the massive extended mags and drum mags.
Stryfe Mission Kit: A SOPMOD styled Stryfe package with a detachable stock that has dart holders, a tactical foregrip, and a Recon/Retaliator-style barrel extension. Includes an 18-dart Clip System magazine with the ammo to match.
Rough Cut 2x4: A pump-action shotgun blaster, the Rough Cut has 8 muzzle-fed barrels and can shoot them off 2 at a time.
Elite Triad EX-3: a unique twist to the Jolt, the Triad has 3 barrels and its air restrictor is designed to only allow one dart to be fired at a time. Its barrel assembly is considerably bulkier, but it's still much smaller than the majority of Elite blasters.
Elite Spectre REV-5 - Released first in Asia, the Elite Spectre is a complete overhaul of its N-Strike predecessor, featuring an improved air restrictor seal mechanism that has been adapted from the Elite Strongarm. Like the original Spectre, it has a detachable folding stock and a barrel extension that cosmetically resembles a suppressor.
Elite Demolisher: A 2014 blaster modeled like a Kalashnikov or a HK-5, with a real integrated underbarrel grenade launcher, mk203 style, that uses a new foam grenade projectile. Ships with a curved "banana" Clip System magazine with a capacity of 10 and and fires Elite Micro darts rapidly using an electrical motor system (4 AA batteries), and possesses a detachable stock that can hold one more Grenade. The Toy Fair prototype is a semi-automatic, but Hasbro intends to make the final product full-auto.
Elite NERF CamECS-12: A rifle-shaped electrically powered blaster that eats lots of batteries (one set for the built-in guncam, one set for the electrical motor). The current prototype is a semi-automatic blaster, like the Demolisher; camera is currently 0.3 megapixels and records at 20fps.
Notable MEGA blasters:
Elite Mega Centurion: An Anti-Materiel Rifle blaster design due in Fall 2013, the Centurion is slated to be one of the longest new blaster designs with its massive 150cm body length from stock to barrel. Features a long plunger draw, a bipod, and is slated to use a larger Elite Mega Dart as opposed to other standard Elite blasters that use streamlined Elite Micro Darts. A sneak preview of the blaster from a Baidu video link led several HvZ players to theorize that the Centurion uses a similar plunger structure to the Stampede sans electrical power.
Elite Mega Magnus◊: A powerful contender for the Hand Cannon of all Nerf handguns, the Magnus has an integrated magazine and can hold 2 darts while chambering a 3rd at the same time. Keep in mind this pistol chambers the same kind of Mega Dart as the Centurion, and is marketed has having a maximum effective range of 85 feet.
Hammer Shot (Article from SGnerf): A 5-shooter revolver with the same basic design, Hammer-action thumb-lever, and shell structure as its sister blaster, the Rebelle Sweet Revenge. Its pistol grip is moulded to simulate wood with tape wrapped around it.
Sledgefire: A break-action Shotgun which can chamber and fire 3 darts at once. It has a fixed stock with integrated ammo holder, and uses shot-shells to hold the darts in threes. Like the N-Strike Barrel Break, it is modeled after a Sawn Off Shotgun, although it is a single-barreled broomhandled stock design rather than the Barrel Break's double-barreled Lupara styling.
Slingfire: A lever-action blaster with a Clip System magazine feed. Fires Elite Micro Darts.
Doublestrike: A double-barreled pistol blaster modeled after the Derringer.
A recently-announced series of Nerf blasters aimed at female Nerf fans, the Rebelle series of blasters is primarily in white, pink, and purple, and most of the blasters announced for launch are comparatively sleeker, more curved, and otherwise less "tacticool" than the typical N-Strike or Vortex blaster. Several blasters are planned to be released with alternate decal patterns such as the Vine and Phoenix designs, and decoratively decal'd darts are available in packs.
Rebelle Heartbreaker Bow◊: A Bow Blaster which appears to take its form from the classic Nerf Big Bad Bow. The Heartbreaker shoots Micro Darts and appears to be made to appeal to girls who enjoyed The Hunger Games.
Nerf N-strike heralded the introduction of gun mods, a natural fit for the semi-realistic designs. Many related accessories were produced by Hasbro for the Vortex blasters as well as the Super Soaker water blasters.
Tactical Rails are like the actual RIS, allowing you to lock on a variety of scopes, grips, bipods, and ammo holders. Tactical Rail kit:
Flip-up sights: 1 variant comes shipped with the Recon CS-6, and another variant is provided by the Longstrike CS-6.
Red Light Sight (Light Beam unit): 1 is provided with the Recon CS-6 and the Elite Retaliator. These have additional Tactical Rails on top.
Green Light Sight (Tactical Light): 1 ships with a special edition of the Barrel Break IX-2.
"Telescopic" Sight: Provided by the Elements IX-6 blaster kit. Does not actually have any focusing lenses, but it DOES have an additional Tactical Rail on top.
Red Dot Sight/ Pinpoint sight: A rare sight that was distributed in limited quantities in several promotions in Singapore, this sight is essentially a Reflex Sight.
Bipod/Tactical Foregrip: Comes with the Stampede ECS. The bipod part retracts inside the foregrip and can be released with the touch of a button.
Assault Grip: A simple foregrip that is provided with the Elite Retaliator.
Ballistic Shield: Comes with the Stampede ECS.
Centerfire Tech Electronic Scope: A scope that was provided with the Vortex Nitron. Features 3 LED-lit trapezoids to help you line up your shots.
Super Soaker Shot Blast Scope: From the 2011 Super Soaker toyline, this scope is about as useful as the Telescopic Sight and is Nerf-compatible.
Ammo holder: Several variants exist, from the Barrel Break's dart holder to the Rebelle Heartbreaker's own dart holder.
AR (Augmented Reality) Attachment, or Mission Central App Cradle: A tac-rail accessory that can hold an Apple iPhone for AR games. Now available in Rebelle colours.
Elite Mega Centurion Bipod: This sniper rifle's bipod is a detachable bipod meant to be mounted underbarrel. Its legs can be swept forwards or backwards.
Switch Shot Sight: A red plastic lens-sight, this was meant to be used with the N-Strike Wii title for revealing hidden messages ingame.
Barrel Extensions lock onto the barrel via a twist-and-lock mechanism, and provide a minor accuracy boost.
Recon Barrel: The Recon's relatively squat barrel extension provides above- and under- barrel Tactical Rails.
Spectre Barrel: The Spectre's barrel extension is designed to resemble a silencer, but it does not provide suppression.
Longstrike Barrel: The Longstrike's lengthy barrel extension provides Tactical Rails like the Recon's does, and it provides a fair amount of accuracy due to its length.
Longshot front blaster: The Longshot CS-6's barrel extension is a blaster in itself. While not very powerful, it has inspired modders to create blaster integrations, Master Key style.
Detachable Stocks come in several configurations, and some of them have unique benefits.
Recon Stock: A thin stock, it has a slot to hold a single 6-dart Clip System magazine.
Raider Stock: An adjustable stock. Very popular with modders for permanent integration in the Power Stock mods. A similar stock was released with the Super Soaker Shot Blast.
Spectre Stock: A foldable stock that can be folded aside for convenience.
Stockade stock: This stock provides room to hold 10 more darts.
Super Soaker Lightningstorm stock: A very sturdy thin white stock with a lightning bolt motif.
Retaliator stock: A short and compact shoulder stock, its form makes it unable to attach to the Vortex Pyragon.
Vortex Praxis stock: A similar thin design to the Recon Stock, the Praxis's stock is unable to hold ammo or magazines.
Demolisher Stock: Has a slot in it to hold another "grenade" for the Demolisher's underbarrel launcher.
Other accessories are available as well.
Quick-Flip Clip Accessory: A plastic clamp that lets you "jungle up" your Clip System magazines. Is sold with some mags and ammo.
Ammo Bandolier: Designed to hold 4 CS Mags and 12 single darts.
Tactical Vest: a child-sized vest designed to hold more mags and ammo. Comes with 2 CS mags and some streamline darts.
Ammo Bag kit: Commonly sold with a bunch of Tagger darts.
Ammo Box kit: Modeled after a realistic ammunition box, this kit is usually sold with large amounts of streamlines.
Vision Gear: Nerf's own in-house protective goggles, child-sized. Protect your eyes!
Decorative Darts: Collect them all!
Camo-patterned darts are a popular thing. The N-Strike Elite series brings this deco to the newer, slightly thicker Elite darts.
Firefly Tech luminous darts work well with most blasters, and are sometimes sold independant of the Lumitron, Firefly, and Rayven.
Rebelle Decorative Dart Pack: A set of Elite-class darts in feminine colours with decorative patterns painted on.
Aftermarket Modding: More Power, More range
While Hasbro officially discourages and recommends against modification of Nerf Blasters, that does not stop the mature fans from breaking out the duct tape and Tim Taylor inside. All proper Nerf fangroups practice safety in their modding, and try to keep the power/pain output of their blaster mods to a minimum.
Classic plunger blaster mods
Velcro Everywhere: a very common trend with Humans VS Zombies players is to employ lots of velcro for holding on to everything, from blasters to Clip System magazines. This also allows players to wear Velcro-based tactical harnesses and hook everything up.
Plunger Padding: An essential mod for blasters with beefed-up springs and removed air restrictors, to cushion the plunger against damage and muffle the plunger slightly.
Body Stuffing/Suppression: To minimize the noise from the internals, you can fill in the deadspace inside a blaster's body and cushion the internals with padding where they touch/rest against the shell. Such stuffing can also be used to alter the mass balance of a blaster to make it either easier to handle or improve accuracy by making it more capable of absorbing recoil from the spring and minimizing vibration.
Spring Upgrade: The most common basic mod for Nerd blasters. Aftermarket Springs can be purchased/fabricated/ordered with additional power.
Air Restrictor Removal: Pretty much all Nerf Blasters have air restrictors/regulators to prevent damage from dry-firing and the regulate air pressure, but they also put a cap on the maximum output of blasters. Many modders take the restrictors out to boost the pressure output. Warning: This mod can reduce the lifespan of the plunger assembly, especially if aftermarket springs are involved.
Rebarreling: A common next-stage mod, this involves replacing the barrel/muzzle of the blaster entirely. Often done to get a better seal/fit for the darts to get more efficient usage of the air pressure.
Custom Breeches: Clip System magazine blasters are sometimes taken to the next level with custom-fabricated breech assemblies , often cast in polycarbon, aluminium, or brass. Legal Warning: some countries, like Singapore and Australia, forbid the importing of brass breeches because they are too distressingly similar to real firearm breech assemblies (although polycarbon boltsled assemblies have managed to pass legal and be imported without any fuss). Some groups, like Orange Mod Works, make and sell custom total breech/spring/trigger catch total internal modkits.
Closed Breeches: a more intensive mod that requires metalworking and precision machining to fit perfectly, the closed breech greatly improves the air seal in the barrel and breech assembly, making the existing plunger more effective at driving the darts.
Torsion Spring: The spring in the Vortex blasters is often a unique shape, and so if you want to customize this part, you'll need to have it fabricated.
More Power: As with the Electrical Blaster Mods detailed below, the electrical Vortex Blasters can be modded accordingly.
Air Pressure System Mods
Bigger pressure chambers, custom regulators: The most obvious way to beef up an Air System blaster is to give it new guts capable of holding more air at a higher pressure. Remember to check for airtight seals for maximum efficiency.
CO2 tank modding: With a proper regulator, fitting a CO2 tank to the blaster's assembly gives you to equivalent of a battery pack for air system blasters.
Electrical Blaster Mods
Battery packs: Self-explanatory. This involves rewiring the blaster to take Lithium cells instead of the typical alkalines. The Humans VS Zombies modders used to love the Trustfire brand lithium cells, but have since moved on to even better brands.
Secondary Trigger Switches: A feature canonized by Hasbro in the Elite Blasters, this involves rewiring the power switch to a secondary trigger on the grip. Older versions of this mod in the Barricade REV-10 involved the unused switch under the trigger, which was positioned like the Nitefinder's half-pull red light sight switch.
Rewiring: As some modders use a lot more power in their electrical blaster mods than stock, they often need to replace the wiring with thicker, better-quality ones to support the increased load. They also do this to rework the internal circuitry of some blasters to eliminate undesired resistance or to make the blaster more power efficient. Caution: take care to wire the electrodes correctly, solder cleanly, and avoid shorting your circuits! It can cause dangerous heat buildup or even destroy your power cells.
Over Volting: For most Electrical Blasters, more power means a faster firing rate and/or more shot power. Warning: Stampedes improperly modded in this fashion can misfire uncontrollably like Kalashnikov gas-piston carbines! Furthermore, heat buildup can melt your blaster.
Replacement gears: A common thing for modders who find the gears inside the mechanism stripping. More durable materials are very welcome for this, like brass or polycarbon.
Flywheel resurfacing: To improve the grip of the flywheels, they can be painted with rubbercoating or given a layer of duct tape. Improves the power and reliability of the flywheels when done correctly.
Custom Engines: For better heat efficiency, reduced noise, or improved power, aftermarket engines can be fitted. Some modders love to use the custom engines from Tamiya car kits.
Stefans: Short, mass-balanced ammo half the length of streamline darts. Require extensive modification to blaster internals before use.
Weighted-head darts: A common modification for darts. Not accepted in most Humans VS Zombies games due to safety concerns, although a properly assembled weighted-head dart with a good glue seal and a properly padded tip can be quite useable otherwise.
Aftermarket darts: A common sight for various reasons like cost/mass difference. Many "brands" of aftermarket darts exist.
Aftermarket Clip System magazines: These exist too. Most commonly seen are rebuilt mags which have been extended, although entirely-original aluminium/brass metal Clip System mags have been seen in some specialist suppliers.
Blaster conversions: A serious kind of total conversion mod, these kinds of mods dramatically rebuild blasters.
Pump Actioning: for a variety of N-strike and Elite blasters like the Recon, Retaliator, and Longshot, modders love to add a pump-action grip to these blasters to make them easier to fire off rapidly.
Singling: Modifying older blasters that fire larger arrows or rockets to fire Micro Darts instead. Watch the air pressure on these things, this mod is highly discouraged by the modding community where some more powerful blasters are concerned.
With the Zombie Strike Sledgefire, modders are anticipating making custom shells that pump the pressure of all three chambers into launching a single dart with triple the power.
A related phenomenon has emerged for the Centurion, with a mod group producing a kit to convert the Elite Mega Centurion to chamber and fire "standard" Elite Micro darts instead of the larger Mega darts.
"Absolving": instead of "Singling" certain kinds of powerful blasters, due to the power available, they can be modified with a custom multi-muzzle turret that turns the blaster into a kind of scattergun that pumps out a huge burst of darts at once, spreading their massive pressure output out to reduce it to less dangerous levels.
Integration: some kinds of blasters are just made to be built into other blasters as extra firepower. Integration involves cutting down a blaster to turn it into a Master Key-like attachment that can be fitted under a barrel.
Some kinds of integrations are made to fit under the N-Strike Barrel Extension attachments and welded/glued/duct-taped in place, so they become removeable from a core blaster by "unscrewing" the barrel attachment they have become a part of. Such attachments may have been inspired by the Longshot's barrel extension frontgun.
Other kinds of integrations are designed around the Tactical Rails, and usually use the smaller blasters such as the Jolt or Reflex or Nitefinder as the donor. These are more modular and become like the Strikefire blaster.
The more permanent integrations are done to "weld" more powerful blasters like the Swarmfire, Speedswarm, or suchlike as a secondary component of the more massive blasters like the Longshot, Stampede, or Hailfire.
Hoppers: Ammo hopper tubes have been developed by canny modders with engineering backgrounds as a natural evolution of rebarreling single-shooters to give them a kind of ammo capacity. Most hoppers are designed to use vacuum action feed to suck darts down the hopper tube and into position in the barrel/muzzle for the next short. Most hoppers are typically designed for use with Streamline Micro darts because of their sleeker body without a bulbous head.
Power Stock: A special mod to allow for more spring power to be packed into a blaster, Power Stocking involves permanently fusing a "detachable" stock, preferably a Raider stock, to the blaster, and reworking the shell and internals so the spring can use the space inside the stock for more compression and thus more power. This mod usually requires the use of an aftermarket spring.
Barricade/Stockade conversion for magazines: A very popular mod amongst Humans vs. Zombies players that eventually inspired Hasbro-Nerf to created the Stryfe. This conversion essentially takes the revolver cylinder out and replaces the deadspace with parts from a cannibalized Raider magwell, allowing the rebuilt blaster to take Clip System magazines.
Ammo Counters: Clip System magazine blasters are known to be modified by some players of Humans VS Zombies to have electronic ammo counters.
Custom N-Strike Accessories: A natural consequence of allowing Gun Accessories is the option to create your own.
Integrated blasters: See above mods - You can heavily rebuild/cut down blasters to turn into attachments that can snap on like barrel extension Master Keys, slide onto the rails as emergency firepower, or just combine multiple blasters for more redundant ammo capacity and More Dakka.
Custom Lights: A common trend for blasters with integrated lights and for the actual Tactical Rail light units is to replace the low-powered red and green LED lamps with something that has more power (Example: Firestrike blaster with a tactical light integration). Warning: Practise good light discipline and safety if using lights above 90 lumen in brightness to avoid eye injuries from glare.
Laser Sights: As with the custom lights, some modders replace the LED lamps with straight-up aligned lasers. Warning: remember to observe safety precautions and discipline as per the laser devices laws (do not point laser at eyes!), and only use low-powered lasers of 3-5 miliwatts or less for sights.
