Deters and repels adversaries with accurate, lethal, direct fire.
The M16A2/A4 Series 5.56mm Rifle provides Soldiers with the ability to deter and, if necessary, repel adversaries by enabling individuals and small unites to engage targets with accurate, lethal, direct fire. It is a gas-operated, air-cooled, shoulder-fired weapon that can be fired either in automatic three-round bursts or semi-automatic single shots. The M16A2 has an integral rear sight, while the M16A4 includes a MIL-STD 1913 upper reciever and forward rail system with a backup iron sight. Both systems can accommodate modern optics, accessories and configurations that incorporate M203 and M320 40mm Grenade Launchers.
