M16A2 Semiautomatic RifleThe M16A2 replaced the M16A1 in U.S. Army service in 1983. It is essentially an improved M16A1. Major changes include: a switch from full automatic to 3-round burst capability; a heavier barrel; improved sights; new, stronger plastic butt stock, hand guard, and pistol grip. The M16A2 has some practical features missing from the M16A1, found on the M4A1 − the prime examples being the ability to rapidly breakdown the gun and field stripping, as well as the high metal parts content. The M16A2 5.56 mm rifle is a lightweight, air-cooled, gas-operated, magazine-fed, shoulder- or hip-fired weapon designed for either automatic fire (3-round bursts) or semiautomatic fire (single shot) through the use of a selector lever. The weapon has a fully adjustable rear sight. The bottom of the trigger guard opens to provide access to the trigger while wearing winter mittens. The upper receiver/barrel assembly has a fully adjustable rear sight and a compensator which helps keep the muzzle down during firing. The steel bolt group and barrel extension are designed with locking lugs which lock the bolt group to the barrel extension allowing the rifle to have a lightweight aluminium receiver.
