A submachine gun (SMG) is a magazine-fed automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun. As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns.
A bayonet is a knife, dagger, sword, or spike-shaped weapon designed to fit on the end of the muzzle of a rifle, carbine, musket or similar firearm, allowing it to be used as a spear-like weapon. From the early 17th to the early 20th century, it was a melee weapon used by infantry for offensive and/or defensive tactics. Today, it is considered an ancillary weapon or weapon of last resort, although it is still used for ceremonial purposes.
The AK-74 is an assault rifle designed by small arms designer Mikhail Kalashnikov in 1974. While primarily associated with the Soviet Union, it has been used by many countries since the 1970s. It is chambered for the 5.45×39mm cartridge, which replaced the 7.62×39mm cartridge of Kalashnikov's earlier automatic weapons for the Soviet Armed Forces.
The Colt AR-15 is a lightweight, magazine-fed, gas-operated semi-automatic rifle. It is a semi-automatic version of the M16 rifle sold for the civilian and law enforcement markets in the United States. The AR in AR-15 stands for ArmaLite rifle, after the company that developed it in the 1950s. Colt's Manufacturing Company currently owns the AR-15 trademark, which is used exclusively for its line of semi-automatic AR-15 rifles.
The Mini-14 is a lightweight semi-automatic rifle manufactured by Sturm, Ruger & Co. Introduced in 1973, the design was outwardly based on the M14 rifle and is, in appearance, a scaled-down version chambered in 5.56×45mm NATO, though with its own gas system design.
The Springfield Armory M1A is a semi-automatic rifle made by Springfield Armory, Inc., beginning in 1971, based on the M14 rifle, for the civilian and law enforcement markets in the United States. "M1A" is a proprietary name for Springfield Armory's M14-pattern rifle. Early M1A rifles were built with surplus G.I. parts until Springfield Armory, Inc. began manufacturing their own. Robert Reese bought Springfield Armory from Elmer Ballance, and moved the manufacturing to Geneseo Ill in 1974.
The Mossberg 500 (M500) is a series of pump action shotguns manufactured by O.F. Mossberg & Sons. The 500 series comprises widely varying models of hammerless repeaters, all of which share the same basic receiver and action, but differ in bore size, barrel length, choke options, magazine capacity, stock and forearm materials. Model numbers included in the 500 series are the 500, 505, 510, 535, and 590. The Revelation 310 and the New Haven 600 were also variations of the 500 series produced by Mossberg under different names. By 2021, 11,000,000 M500s had been produced, making it the most-produced shotgun of all time.
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 Type 56 is a Chinese 7.62×39mm rifle and a variant of the Soviet-designed AK-47 and AKM rifles. The Type 56 rifle was designated by the Chinese military as the "Type 1956 Submachine Gun", because the Type 56 took the role of SMG rather than infantry service rifle in the PLA in the rifle's early service years. Production started in 1956 at State Factory 66 but was eventually handed over to Norinco and PolyTech, who continue to manufacture the rifle primarily for export.
The RPK, sometimes retroactively termed the RPK-47, is a Soviet 7.62×39mm light machine gun that was developed by Mikhail Kalashnikov in the early 1960s, in parallel with the AKM assault rifle. It was created to standardize the small arms inventory of the Soviet Army, where it replaced the 7.62×39mm RPD machine gun. The RPK continues to be used by the military of the post-Soviet states and certain African and Asian nations. The RPK is also manufactured in Bulgaria, Hungary, Romania, and Serbia.
The Type 99 light machine gun was a light machine gun used by the Imperial Japanese Army in World War II. It was similar in design to the earlier Type 96 light machine gun, but designed to fire the new and more powerful 7.7×58mm Arisaka cartridge, which improved energy by over 50%. Other improvements included the omission of the oiling mechanism which resulted in a better all-round weapon. The Type 99 never fully replaced the previous models of Japanese light machine guns, and served alongside the Type 11 and Type 96 until 1945. Like the Type 96, the Type 99 traces its history to the ZB vz. 26, which also inspired the British Bren light machine gun.
The RK 95 TP, officially 7.62 RK 95 TP and commercially known as the M95, is a 7.62×39mm Finnish assault rifle adopted in relatively small numbers by the Finnish Defence Forces in the 1990s.
A muzzle booster or recoil booster is a device fixed to the muzzle of a firearm, intended to harness the energy of the escaping propellant to augment the force of recoil on portions of the firearm. In spite of its name, a muzzle booster does not increase muzzle force or velocity but instead is usually used to improve the reliability and/or rate of fire of a recoil operated firearm. It was invented by Hiram Maxim in 1894.
The SG 550 is an assault rifle manufactured by SIG Sauer AG in Switzerland. "SG" is an abbreviation for Sturmgewehr. The rifle is based on the earlier 5.56×45mm NATO SIG SG 540.
A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long gun which needs to be held by both hands and braced against the shoulder. Handguns have shorter effective ranges compared to long guns, and are much harder to shoot accurately. While most early handguns are single-shot pistols, the two most common types of handguns used in modern times are revolvers and semi-automatic pistols, although other handguns such as derringers and machine pistols also see infrequent usage.
The Mendoza RM2 was a light machine gun similar to the M1918 BAR manufactured in Mexico by Productos Mendoza, S.A. Rafael Mendoza have been producing machine guns for the Mexican Army since 1933 and all have been noted for their lightness, simplicity, ease of maintenance, and economic construction without sacrificing reliability.
A barrel shroud is an external covering that envelops the barrel of a firearm, to prevent unwanted direct contact with the barrel. Moving coverings such as pistol slides, fore-end extension of the gunstock/chassis that do not fully encircle the barrel, and the receiver of a firearm itself are generally not described as barrel shrouds, though they can functionally act as such.
