Since its introduction in the late-1950's the AR-15 has been the standard by which all other assault rifles are judged. The AR-15's straight-line stock design eliminates the fulcrum created by traditional bent stocks, reducing muzzle climb. The aircraft grade aluminum receiver is lightweight and highly corrosion-resistant and the synthetic stock and grips do not warp or splinter. The AR-15's direct impingement gas system is fast-acting and reliable whether housed in the US Military's M-16 or a civilian AR-15. This early pre-ban rifle features a folding peep rear sight with an adjustable pin front, a toggle safety, a flash hider, a bayonet lug, and a 20-round magazine. Its synthetic stock, its metal, and its bore are all in very good condition.
