Gun Nut

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 large collection of them. Due to various laws regarding firearm ownership and use, the Gun Nut does not actually have to meet all these criteria, as long as they are truly obsessed with guns. When the Russians invade or the Zombie Apocalypse occurs, you can expect this person to step up to the plate.

This character is not automatically The Gunslinger, a Crazy Survivalist, or Trigger Happy; 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 Knife Nut, Pyromaniac. There's also "geardos" for Gun Accessories.

Anime And Manga

 * Sosuke from Full Metal Panic is a major gun nut, as well as being rather Trigger Happy and storing large amounts of guns into Hammerspace.
 * Shinji loves all things military, with his love of guns only second to Humongous Mecha. 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.
 * Highschool of the Dead: 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.
 * Patlabor's Isao Ota is essentially Tackleberry with a Humongous Mecha and Testosterone Poisoning.

Film

 * Billy Rosewood reveals himself to be one in Beverly Hills Cop 2.
 * Tackleberry from the Police Academy films is a big gun nut, as is his mother and his girlfriend & her family.
 * Burt Gummer 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. Burt's wife, Heather, was also a gun nut.
 * 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.

Literature

 * Hazel D'Ark of the Deathstalker novels really, really likes guns, especially when she learns about projectile weapons.

Live Action Television

 * Chuck: 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 Buy More has guns in it. To top it all of, he has a picture of Ronald Reagan on the wall in his house.
 * Eureka: Jo, current GD head of security, former deputy and Army Ranger, has gun tropes galore. In addition to the Wall of Weapons she keeps in the Sheriff's office, her love of BFGs, and a tendency to be Trigger Happy, she also can be seen reading magazines throughout the series, with names such as Modern Mercenary.
 * Jayne from Firefly has a Wall of Weapons. He's freakishly fond of them, particularly Vera.
 * Robin from How I Met Your Mother qualifies. She prefers "gun enthusiast" though.
 * Sledge Hammer 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 flare pistol to rocket launcher.

Video Games

 * Fallout has a character perk called "Gun Nut" that gives your character improvements concerning the use and maintenance of firearms.

Web Original

 * FPS Russia

Western Animation

 * Dale Gribble from King of the Hill has this a little bit. He's also a bit of a Miles Gloriosus with his exploits as well.

Real Life

 * R. Lee Ermey is such a gun nut, he even had two shows on The History Channel about guns. Mail Call, which lasted seven years, featured him reading people's questions about guns (as welother military-related questions, usually involving explosions), then going down to a military base and getting Trigger Happy 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 ballistic on watermelons.
