[[caption-width-right:306:[[WallOfWeapons Still not enough gun]].]]

->''"I am Heavy Weapons Guy...and this [grabs Minigun] is my weapon. She weighs one hundred fifty kilograms and fires two hundred dollar, custom-tooled cartridges at ten thousand rounds per minute. It costs four hundred thousand dollars to fire this weapon... for twelve seconds."''
-->-- ''VideoGame/TeamFortress2''

A character whose life revolvers around guns. They like to read about them, have memorized large amounts of facts about guns, know all the models and ammo types, subscribe to the magazines, are in the [=NRA=], make frequent trips to the gun range, and have a [[WallOfWeapons large collection of them]]. Due to various laws regarding firearm ownership and use, the GunNut does not actually have to meet ''all'' these criteria, as long as they are truly obsessed with guns. When the [[RedScare Russians invade]] or the ZombieApocalypse occurs, you can expect this person to step up to the plate.

This character is ''not'' automatically TheGunslinger, a CrazySurvivalist, or TriggerHappy; it is common for the creator of a work to just lump these traits into the same character, so there is often overlap. See also PyroManiac. There's also "geardos" for GunAccessories.

Note that people in RealLife who fit this trope often find the term derogatory, for [[CaptainObvious obvious]] reasons, and it's not a good idea to piss these people off.

!!Examples:

[[foldercontrol]]

[[folder: Anime And Manga]]
* [[MadScientist Professor Shikishima]] from ''Manga/GetterRobo'' is this trope incarnate, emphasis on the ''nuts'' part. Almost any time he's on screen (or on panel, manga-wise) he's fooling around with guns or coming up with a new ridiculously overkill weapon for the protagonists to use.
* Sosuke from ''LightNovel/FullMetalPanic'' is a major gun nut, as well as being rather TriggerHappy and storing large amounts of guns into HammerSpace.
** Shinji loves all things military, with his love of guns only second to HumongousMecha. When he bumps into Sosuke on Kanami's deck they get so distracted talking about weapons that they forget why they were even there in the first place.
* ''HighSchoolOfTheDead'': Kohta is a self-proclaimed "gun otaku", but as he is a sixteen-year-old in Japan, he doesn't actually own any. He did however go to America and learn how to shoot at an [=NRA=] camp.
* ''Anime/{{Patlabor}}'s'' Isao Ota is essentially [[PoliceAcademy Tackleberry]] with a HumongousMecha and TestosteronePoisoning.
* Yoichi Hiruma from ''Manga/{{Eyeshield 21}}''.
* Ryo Saeba from ''Manga/CityHunter''. He's an expert, has quoted some random facts (when they were relevant to the plot, but he still did it), owns a large collection, and is often seen shooting in the range in the ''basement of his own home'' (this is [[JustifiedTrope justified]]: given Japanese gun laws, that shooting range and collection of his are illegal and a one-way ticket to prison if discovered by a cop who actually cares).
* Rally Vincent of ''GunsmithCats''. She's studied guns ''so much'' she can learn all sorts of things just by looking at them or holding them (such as knowing whether or not it's loaded). Even worse, she faked her age (gun laws where she lives require her to be 21; she's only 19). And then there was the time she used her gun in a ''[[CargoShip very]]'' naughty way...
* The incarnations of Maya Jingu in ''[[{{Anime/Burn Up}} Burn Up W/Excess]]'' and ''Burn Up Scramble'' achieve the trope in slightly different ways. In ''W/Excess'', she keeps a WallOfWeapons and [[ICallHerVera each of her guns is named]], and she goes pretty nuts when she can't shoot. In ''Scramble'', her obsession appears in the fact she keeps guns everywhere...usually next to her other obsession: ''plushies''.
* Ritsuko Inoue from ''ThoseWhoHuntElves''. Her gun-nuttiness is a natural extension of her obsession with [[SmallGirlBigGun all things military]].
* Shino Asada of ''LightNovel/SwordArtOnline''. She's a bit of a unique case, however: she's severely gun-phobic due to an incident with an armed robber when she was younger. She took up the hobby in an attempt to "face her fears" and conquer said phobia. It's not too effective, as she still freaks out upon seeing a real gun, or even a realistic model.

[[folder:Comics]]
* Brainstorm, inventor and master weapon designer of ''ComicBook/TransformersMoreThanMeetsTheEye''. Unlike most examples he is tends to more interested in developing new firearms than actually fighting. Whirl from the same series is a straight example.
* Minor Franchise/{{Batman}} villain Gunhawk falls into this category, as does his girlfriend Bunny. Bunny later split from Gunhawk and developed her owned costumed villain identity as Pistolera.

[[folder:Fanfiction]]
* Diego from ''Fanfic/TheStrexFamily'' to the point that one of his [[CharacterBlog Character Blogs]] [[RunningGag regularly posts photosets of guns with comments like "want" or "I want that".]]
[[/folder]]

[[folder:Film]]
* Billy Rosewood reveals himself to be one in ''BeverlyHillsCop 2''.
* Tackleberry from the ''PoliceAcademy'' films is a big gun nut, as is his mother and his girlfriend (later wife) & her family. Some of his side of the family are nuts, too. If not, it's because they're {{Boisterous Bruiser}}s instead who sucker-punch each other for fun.
* Burt Gummer from ''Film/{{Tremors}}'' loves his guns, and cleans them lovingly. He's such a nut (and the monsters are that badass) that he bought himself an anti-aircraft artillery cannon. By the later installments of the series, his "home" is one hell of an underground bunker. He married Heather because she was just as obsessed with guns (not just any weapons, but guns!) as he was. They had trained the rest of the town on survival techniques before the movie began. (They live in the middle of nowhere; survival strategies are necessary.) After the first time, Heather left Burt and took half the guns with her. (the monsters had left them with half a house already). In the fourth movie, we see Burt's ancestor; his interaction with the monsters prompts the gun nut trait.

[[folder:Literature]]
* Hazel D'Ark of the ''Literature/{{Deathstalker}}'' novels really, really likes guns, especially when she learns about projectile weapons.
* The [[BadassFamily famous, infamous Whistler family]] of ''Literature/ABrothersPrice'' is said to be this collectively. Captain Tern tells her princess that she suspects the girls get gun-shaped teething rings when they're tiny and start rifle training at eight. It may actually be earlier. However, the family itself is fairly varied.
* [[HiredGun Kincaid]] from the ''Literature/DresdenFiles'' series qualifies, not so much for quantity as depth of knowledge and customization; in addition to his signature SniperRifle, he's been seen sporting {{Hand Cannon}}s and several shotguns with [[DepletedPhlebotinumShells custom loads]]. He's brought up a few times in the accompanying [[TabletopGame/TheDresdenFiles RPG books]], mostly in relation to the Stunts associated with the Guns skill, which allow players to make their own Gun Nut to taste.
%%* Literature/NamingTheHangman: Billy Calloway. He spends lots of money on expensive military-grade firearms. Izzy suggests that he may be CompensatingForSomething.

[[folder: Live Action Television]]
* ''Series/{{Chuck}}'': [[ColonelBadass Colonel John Casey]] is one, as you'd expect one of the world's greatest gunmen and snipers to be. He has guns hidden ''everywhere'', even his locker at the [[SouLSuckingRetailJob Buy More]] has guns in it. To top it all of, he has a picture of Ronald Reagan on the wall in his house.
* ''Series/{{Eureka}}'': Jo, current [=GD=] head of security, former deputy and Army Ranger, has gun tropes galore. In addition to the WallOfWeapons she keeps in the Sheriff's office, her love of {{BFG}}s, and a tendency to be TriggerHappy, she also can be seen reading magazines throughout the series, with names such as ''Modern Mercenary''.
* Jayne from ''Series/{{Firefly}}'' has a WallOfWeapons. He's freakishly fond of them, particularly [[ICallItVera Vera]].
* Robin from ''Series/HowIMetYourMother'' qualifies. She prefers [[InsistentTerminology "gun enthusiast"]] though.
* Series/SledgeHammer takes it to another level: He seems to have a deep relationship with his Magnum e.g. he shares his bed with his gun, takes it into the shower and frequently talks to it. He also uses several other firearms from [[http://www.imfdb.org/wiki/Sledge_Hammer#M8_Flare_Pistol flare pistol]] to [[http://www.imfdb.org/wiki/Sledge_Hammer#M72_LAW rocket launcher]].
* Lassiter of ''Series/{{Psych}}'' also qualifies as this. He's also CrazyPrepared, hiding dozens of guns in his apartment. One episode had the police confiscate guns from apartment, some of which they couldn't even find such as the one hidden in a bowl of M&Ms and one hidden in his shower head.
* Lester's brother Chaz in ''Series/{{Fargo}}''. He has a huge collection of guns and just about every time we see him, he is doing something involving his gun collection: cleaning them, shooting them, etc.

[[/folder]]

[[folder: Video Games]]
* ''VideoGame/{{Fallout 3}}'' has a character perk called "Gun Nut" that gives your character improvements concerning the use and maintenance of firearms.
* ''ResidentEvil'': Barry Burton is probably the most clear-cut example, wielding his beloved Colt Python. Secondary character Robert Kendo, who designed the upgraded S.T.A.R.S. "Samurai Edge" pistol is likely another example, although as the series veered further into GunPorn it's hard to find a protagonist that doesn't lovingly customize their firearms.

* [[http://www.youtube.com/user/FPSRussia?feature=g-u FPS Russia]]
* Tord from ''{{Eddsworld}}'', his favourite being an [[MotherRussiaMakesYouStrong AK47]].

[[folder: Western Animation]]
* Dale Gribble from ''WesternAnimation/KingOfTheHill'' has this a little bit. He's also a bit of a MilesGloriosus with his exploits as well.
* Stan from ''WesternAnimation/AmericanDad'' has guns behind every wall in his house, including one in his pillow. He even talks to them.
* [[WesternAnimation/TheSimpsons "When do we get the FREAKIN' GUNS?!?!?"]]
[[/folder]]

[[folder: Real Life]]
* RLeeErmey is such a gun nut, he even had ''two'' shows on TheHistoryChannel about guns. ''Mail Call'', which lasted seven years, featured him [[ExcusePlot reading people's questions]] about guns (as well as other military-related questions, usually involving explosions), then going down to a military base and getting TriggerHappy as he explained the weapon. ''Lock N' Load'' was a short series where he talked about the history of various guns (and tanks, knives, artillery) and then went [[IncrediblyLamePun ballistic]] on watermelons.
* Creator/LarryCorreia is even more of one than his books would indicate. He used to hold a Federal Firearms License (allowing him to operate a business that involves firearms) and was licensed as a Title 7 Special Occupational Taxpayer (allowing him to possess machine guns registered since 1986 as part of his business, among other things).
