The 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.
The term "AR-15" signifies "Armalite rifle, design 15".[8] Today, Colt uses "AR-15" for its semi-automatic civilian rifles, and thus many use the term only for Colt AR-15s and clones made by other manufacturers. This article discusses the original design intended for military users and its major variants.
AR-15 rifles are lightweight, gas-operated, magazine-fed, and air-cooled. They fire an intermediate cartridge, and are manufactured with extensive use of aluminum alloys and synthetic materials. The design splits the rifle into two major components: the lower half, containing the trigger and buttstock, and the upper half, which contains the bolt and barrel. This approach allows modular replacement of components.
The name AR-15 remains a Colt registered trademark, but variants of the firearm are made, modified, and sold under various names by multiple manufacturers.
