AR-15 variant

An AR-15 variant refers to a lightweight, intermediate cartridge magazine-fed, air-cooled semi-automatic rifle with a rotating lock bolt, actuated by direct impingement gas-operation or long/short stroke piston operation. The prototype AR-15 rifle was designed by ArmaLite as a selective fire weapon for military purposes. Armalite sold the design to Colt due to financial difficulties. After some modifications, the rifle eventually became the US Army's M16 rifle. A civilian version was marketed as the Colt AR-15 rifle.
