The Colt AR-15 is a product line of magazine-fed, gas-operated, autoloading rifle manufactured by Colt's Manufacturing Company ("Colt") in many configurations. The rifle is a derivative of its predecessor, the lightweight ArmaLite AR-15, an automatic rifle designed by Eugene Stoner and other engineers at ArmaLite in 1956.
The M4 carbine is a 5.56×45mm NATO assault rifle developed in the United States during the 1980s. It is a shortened version of the M16A2 assault rifle. The M4 is extensively used by the US military, with decisions to largely replace the M16 rifle in US Army and US Marine Corps combat units as the primary infantry weapon and service rifle. The M4 has been adopted by over 60 countries worldwide, and has been described as "one of the defining firearms of the 21st century".
A magazine, often simply called a mag, is an ammunition storage and feeding device for a repeating firearm, either integral within the gun or externally attached. The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a "clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine or cylinder.
The Colt Automatic Rifle-15 or CAR-15 is a family of M16 rifle–based firearms marketed by Colt in the 1960s and early 1970s. However, the term "CAR-15" is most commonly associated with the Colt Commando ; these select-fire carbines have ultrashort 10.5-inch (270 mm) and 11.5-inch (290 mm) barrels with over-sized flash suppressors.
The .410 bore (10.4 mm) is one of the smallest caliber of shotgun shell commonly available. A .410 bore shotgun loaded with shot shells is well suited for small game hunting and pest control. The .410 started off in the United Kingdom as a garden gun along with the .360 and the No. 3 bore (9 mm) rimfire, No. 2 bore (7 mm) rimfire, and No. 1 bore (6 mm) rimfire. .410 shells have similar base dimensions to the .45 Colt cartridge, allowing many single-shot firearms, as well as derringers and revolvers chambered in that caliber, to fire .410 shot shells without any modifications.
The .22 Hornet or 5.6×36mmR Hornet is a varminting, small-game hunting, survival and competition centerfire rifle cartridge commercially introduced in 1930. It is considerably more powerful than the rimfire .22 WMR and the .17 HMR, achieving higher velocity with a bullet twice the weight of the .17 HMR bullet. The Hornet also differs significantly from these in that being a centerfire cartridge makes it reloadable, and thus more versatile. It was the smallest commercially available .22 caliber centerfire cartridge until the introduction of the FN 5.7×28mm.
The Robinson Armament Co. XCR is a multi-caliber, gas piston weapon system developed by Robinson Armament Co. for U.S. Special Operations Command (SOCOM) to fill the requirements of the SOF Combat Assault Rifle, or SCAR competition, but was disqualified on a technicality due to late delivery of blank firing adapters. It has been offered to law enforcement, the military, and the general public since 2006.
The Colt Automatic Rifle or Colt Light Machine Gun is a 5.56 mm NATO, open-bolt, full-automatic-only firearm developed by Colt Defense. It is based on the M16A2/A4, and has a distinctive squared-off handguard, vertical grip, carrying handle and integrated bipod.
The ArmaLite AR-7 Explorer is a semi-automatic firearm in .22 Long Rifle caliber, developed in 1959 from the AR-5 that was adopted by the U.S. Air Force as a pilot and aircrew survival weapon. The AR-7 was adopted and modified by the Israeli Air Force as an aircrew survival weapon in the 1980s.
The Barrett REC7 is an American firearm manufactured as a selective-fire fully-automatic and semi-automatic rifle by Barrett Firearms. It is an M4 carbine utilizing a short-stroke gas piston system and is available in either 5.56×45mm NATO or 6.8mm Remington SPC. The REC7 is Barrett's second AR-pattern rifle chambered for the 6.8mm Remington SPC cartridge, the first being the Barrett M468 rifle. The 6.8 SPC-chambered M468 rifle employed the same Stoner expanding gas system as the M4.
The ArmaLite AR-5 is a lightweight bolt-action takedown rifle chambered for the .22 Hornet cartridge and adopted as the MA-1 aircrew survival rifle by the United States Air Force. It was developed by ArmaLite, a division of Fairchild Engine and Airplane Corporation in 1954.
A combination gun is a firearm that usually comprises at least one rifled barrel and one smoothbore barrel, that is typically used with shot or some type of shotgun slug. Most have been break-action guns, although there have been other designs as well. Combination guns using one rifled and one smoothbore barrel are commonly found in an over-and-under configuration, while the side-by-side configuration is usually referred to as a cape gun. A combination gun with more than two barrels is called a drilling with three barrels, a vierling with four barrels, and a fünfling with five barrels. Combination guns generally use rimmed cartridges, as rimless cartridges are usually more difficult to extract from a break-action firearm.
The M6 Aircrew Survival Weapon was a specially-made .22 Hornet over .410 bore combination gun issued to United States Air Force aircrews to help forage for food in the event of a plane crash. It was issued from 1952 until the early 1970s, in conjunction with the M4 Survival Rifle. Plans to replace both with the ArmaLite AR-5 never came to fruition and in 2018 was instead replaced with the GAU-5A Aircrew Self Defense Weapon in some instances.
The M6 is a series of carbines designed and manufactured by LWRC International. It is based on the M4 carbine, with which it shares 80% of its parts. The 'M' model name is not a US military designation. Like the HK416, it features a proprietary short-stroke self-regulating gas piston system and bolt carrier/carrier key design, which prevents trapped gases from contacting the bolt carrier or receiver of the weapon. The manufacturer claims that this reduces the heating and carbon fouling of the internals, simplifies field maintenance, and improves reliability.
The Springfield Armory M6 Scout is a .22 Hornet over .410 bore combination gun that is virtually identical to the original M6 Aircrew Survival Weapon. It is also made in .22 Long Rifle over .410 bore and .22 Magnum over .410 bore. The Scouts are made with 18.25 inches (46.4 cm) barrels, as opposed to the original M6's 14 inches (36 cm) barrel length, to comply with National Firearms Act. The later models have large over-sized trigger guards and Picatinny rails for mounting a wide range of sights and scopes. They come in stainless steel or with a Parkerized finish.
The TP-82 is an out-of-service triple-barreled Soviet combination gun carried by cosmonauts on space missions. It was intended as a survival aid to be used after landings and before recovery in the Siberian wilderness.
The M30 Luftwaffe Drilling ("triple") was a survival weapon issued to Luftwaffe pilots during World War II. It was used by airmen operating in Northern Africa. The M30 was intended to be used for hunting and self-defense against a variety of natural predators.
The Adaptive Combat Rifle (ACR) is a modular assault rifle formerly designed by Magpul Industries of Austin, Texas, and known initially as the Masada.
An AR-15–style rifle is a lightweight semi-automatic rifle based on or similar to the Colt AR-15 design. The Colt model removed the selective fire feature of its predecessor, the original ArmaLite AR-15, which is a scaled-down derivative of the AR-10 design. It is closely related to the military M16 rifle.
