A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries.
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. The submachine gun was developed during World War I (1914–1918) as a close quarter offensive weapon, mainly for trench raiding. At its peak during World War II (1939–1945), millions of submachine guns were made for assault troops and auxiliaries whose doctrines emphasized close-quarter suppressive fire. New submachine gun designs appeared frequently during the Cold War, especially among special forces, covert operation commandos and mechanized infantrymen. Submachine gun usage for frontline combat decreased in the 1980s and 1990s, and by the early 21st century, submachine guns have largely been replaced by assault rifles, which have a longer effective range, have increased stopping power, and can better penetrate the helmets and body armor used by modern soldiers. However, they are still used by security forces, police tactical units, paramilitary and bodyguards for close-quarters combat because they are "a pistol-caliber weapon that's easy to control, and less likely to overpenetrate the target".
A bayonet is a knife, dagger, sword, or spike-shaped melee weapon designed to be mounted on the end of the barrel of a rifle, carbine, musket or similar long firearm, allowing the gun to be used as an improvised spear in close combats.
The AK-74 is an assault rifle designed by small arms designer Mikhail Kalashnikov in 1974 as a successor to the AKM. 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.
A muzzle brake or recoil compensator is a device connected to, or a feature integral to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported.
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.
A grenade launcher is a weapon that fires a specially designed, large-caliber projectile, often with an explosive, smoke, or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organization by military forces.
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.

Robert Reese bought Springfield Armory from Elmer Ballance and moved the manufacturing from Devine, Texas to Geneseo, Illinois in 1974.

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, about 11 million 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.

The RPK, sometimes inaccurately 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.

A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long barreled gun which typically is intended 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.
The Mendoza RM2 was a light machine gun manufactured in Mexico by Productos Mendoza, S.A..
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 extensions 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.
