The M16A2 service rifle is a light weight, magazine fed, air cooled, gas operated, shoulder fired weapon, capable of firing either semi-automatic or three-round burst. The M16 has been the service rifle of the Marine Corps since the mid-1960s, and every Marine is trained to fire it. The M16A2 service rifle was updated for greater adaptability with the M16A4 model during Operation Iraqi Freedom. The M16A4 incorporates a flat-top receiver unit for mounting optical sights, lasers, night-vision devices, forward handgrips, a removable carry handle and flashlights.
