The Bushmaster name goes back when AR15s were made by a handful of quality companies. After the bankruptcy of Remington Outdoors, the liquidators have found some new old stock of solid value Bushmaster upper receiver groups, and Charlie's is proud to offer vintage new old stock for a general purpose build.
This Bushmaster XM15 QRC (Quick Response Carbine) upper will attach to virtually any standard AR-15 lower receiver. Comes complete with charging handle, forward assist, ejection port cover, bolt and bolt carrier assembly. With a 1 in 8" twist, the 16" barrel provides outstanding accuracy that has been enjoyed by competition shooters worldwide. Pre-ban style upper includes a bayonet lug and flash hider.
