M4 Carbine

The M4 Carbine is an American designed assault rifle manufactured by Colt's Manufacturing Company, it is one of the current standard service rifle of the US Military and has been appeared in many video games.

History
The M4 Carbine was first introduced in 1994, its the carbine version of the M16A2 assault rifle. The weapon was designed to replaced the older versions of M16 carbines (CAR-15) in service within the US Armed Forces. The M4 serves as the standard rifle of the US Military, and has been also exported to other countries. It is usually seen in the hands of operatives from military special forces and special police units.

Design Features
The M4 Carbine uses the same direct impingement gas system and rotating bolt system as the M16 rifle. It fires the 5.56x45mm NATO small-caliber rifle cartridge and fed from a 30-round STANAG magazine (other rounders such as the C-MAG drums are also available). Unlike the M16, the M4 features a multi-position telescoping buttstock, and the carrying handle is removable for mounting optics and accessories via MIL-STD-1913 Picatinny rail, which has installed on top of the receiver. Same as the M16, the M4 is an selective fire weapon, it can be fired in either semi-automatic or 3-round burst (Auto for M4A1). The weapon has 80% parts compatible with the M16A2. In conclusion, the M4 is an compact, light and accurate weapon, although the weapon is notorious for its bad reliability in extreme conditions.
