The M4 carbine (officially Carbine, Caliber 5.56 mm, M4) 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 M4A1 is built around a 14.5 inch Cold Hammer Forged M4 Profile barrel with a permanently attached Daniel Defense Flash Suppressor. The independently ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters.

The M4A1 is a 5.56mmx45mm NATO caliber weapon with a gas operated, rotating bolt action. The carbine is typically fed from 30-round STANAG magazines. A single Picatinny rail is Featured atop the M$A1's M16A3-style falt-top receiver for mounting scopes, sights or a carrying handle.

The M4A1 is a fully automatic variant of the M4 carbine – a shorter and lighter variant of the M16. It went into service in 1994 to replace the M16 in certain roles. The M4A1 trigger group operates on either Safe, Semi-Automatic, or Fully Automatic settings.

The M4 carbine can deliver semi-automatic fire and 3-round bursts, and its safety/fire selector lever is appropriately marked “Safe – Semi – Burst”. The M4A1 carbine does not have a burst limiting mechanism in its trigger unit, and its selector is marked “Safe – Semi-Auto”.

The M4A1 is a high-tech, multiple-use assault rifle that can be configured by the operator with multiple combinations of advanced optics, lasers and lighting systems for rapid and accurate target acquisition in daylight or at night.
