ArmaLite AR-15 The ArmaLite AR-15 was a select-fire, air-cooled, gas-operated, magazine-fed assault rifle manufactured in the United States between 1959 and 1964. Designed by American gun manufacturer ArmaLite in 1956, it was based on its AR-10 rifle. The ArmaLite AR-15 was designed to be a lightweight assault rifle and to fire a new high-velocity, lightweight, small-caliber cartridge to allow the infantrymen to carry more ammunition.[4]
