The AR-15 is a semi-automatic rifle made by ArmaLite in 1958 by Eugene Stoner. It is the civilian version of the M-16 ("M" standing for "Military"). AR is the two letter abbreviation for the company that first manufactured the weapon, "ArmaLite" and "Rifle," ArmaLite Rifle (AR). The military version, is the M-16, manufactured by Colt Firearms. The M-16, unlike the AR-15 is a fully automatic, magazine fed, gas operated, shoulder fired assault rifle. The M-16 first saw combat in the Vietnam War. The AR-15 is a lightweight, intermediate cartridge magazine-fed, air-cooled rifle with a rotating lock bolt, actuated by direct impingement gas operation or long/short stroke piston operation. It has been produced in many different versions, including numerous semi-automatic and select fire variants. It is manufactured with extensive use of aluminum alloys and synthetic materials.
