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 aluminium 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. The AR-15 Sporter II has a removable carry handle with an adjustable sight and a 20" with a flash hider. This semi-automatic rifle features an aftermarket quadrail, a foldable foregrip, and a 30-round magazine. Its stock, metal, and bore are all in very good condition.
