The M4 carbine outshines its predecessor, the M16A2 assault rifle, with its significantly shorter and lighter design. Chambered in 5.56×45mm NATO, this air-cooled, gas-operated, magazine-fed carbine boasts a 14.5 in (370 mm) barrel paired with a telescoping stock that enables enhanced maneuverability. The M4 carbine is widely employed by the United States Armed Forces and has largely taken over as the primary infantry weapon and service rifle in United States Army and United States Marine Corps combat units, effectively replacing the M16 rifle.
