AR-15 Semi Automatic Rifle 


An AR-15 style rifle is a lightweight semi-automatic rifle based on the ArmaLite AR-15 design, which is itself a scaled-down derivative of Eugene Stoner’s AR-10 design. ArmaLite sold the patent and trademarks to Colt’s Manufacturing Company in 1959. After Colt’s patents expired in 1977, Colt retained the trademark and is the exclusive owner of “AR-15” designation.
