ar 15 upper

The Colt AR-15 is a lightweight, 5.56×45mm, magazine-fed, gas-operated semi-automatic rifle. It was designed to be manufactured with the extensive use of aluminum alloys and synthetic materials.
Introduced in 1964, Colt has made many different types of AR-15 rifle and carbine models. Other manufacturers now make AR-15 copies and clones marketed under separate designations, although these are frequently referred to as AR-15s. This article discusses the semi-automatic version manufactured by Colt.
