The Galil is a family of Israeli made automatic rifles designed by Yisrael Galil and Yaacov Lior in the late 1960s, and produced by Israel Military Industries (IMI). The design is closely based on the Valmet Rk 62, which is itself an improved version of the Soviet AK-47. The first Galils were manufactured using Valmet Rk 62 receivers. Most Galils are chambered for either the 5.56×45mm NATO or 7.62×51mm NATO cartridges. The Galil series of weapons is in use with military and police forces in over 25 countries.
In firearms terminology, an action is the functional mechanism of a breech-loading weapon that handles the ammunition, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot weapons with a closed off breech and the ammunition is manually loaded through the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the lock,.
The Colt AR-15 is a lightweight, 5.56×45mm, magazine-fed, gas-operated semi-automatic rifle. The "AR” stands for ArmaLite Rifle. It was designed to be manufactured with extensive use of aluminum alloys and synthetic materials. Colt was but no longer is marketing to civilian customers and is presently only marketing to law-enforcement customers, due to oversaturation in the civilian market. Colt's Manufacturing Company currently uses the AR-15 trademark for its line of semi-automatic AR-15 rifles.
The M4 Carbine is a lighter and shorter variant of the M16A2 assault rifle. The M4 is a 5.56×45mm NATO, air-cooled, gas-operated, direct impingement, magazine-fed carbine. It has a 14.5 in (370 mm) barrel and a telescoping stock.
Direct impingement is a type of gas operation for a firearm that directs gas from a fired cartridge indirectly into the bolt carrier or slide assembly to cycle the action.

The ArmaLite AR-15 is a select-fire, air-cooled, gas-operated, magazine-fed rifle manufactured in the United States between 1959 and 1964, and adopted by the United States Armed Forces as the M16 rifle. Designed by American gun manufacturer ArmaLite in 1956, it was based on its AR-10 rifle.

The Stoner 63, is a 5.56×45mm NATO, modular weapon system, using a variety of modular components, it can be configured as a rifle, a carbine, a top-fed light machine gun, a belt-fed squad automatic weapon, or a vehicle mounted weapon. Also known as the M63, XM22, XM23, XM207 or the Mk 23 Mod 0 machine gun, it was designed by Eugene Stoner in the early 1960s. Cadillac Gage was the primary manufacturer of the Stoner 63 during its history. The Stoner 63 saw very limited combat use by United States forces during the Vietnam War, including the Navy SEALs and Marine Corps. A few were also sold to law enforcement agencies.
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge.
A breechblock is the part of the firearm action that closes the breech of a weapon at the moment of firing.
Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber. Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action.
A hydraulic cylinder is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke. It has many applications, notably in construction equipment, manufacturing machinery, and civil engineering.
The RPD is a 7.62mm light machine gun developed in the Soviet Union by Vasily Degtyaryov for the 7.62×39mm M43 intermediate cartridge. It was created as a replacement for the DP machine gun chambered for the 7.62×54mmR round. It is a precursor of most squad automatic weapons. It was succeeded in Soviet service by the RPK.
