MidwayUSA is proud to offer this AR-STONER™ A3 Upper Receiver Assembly at an exceptional price! This AR-Stoner carbine length upper features a mil-spec bolt carrier group, phosphate finish, A2 fixed front sight, and a heavy profile barrel. The A3 upper will attach to virtually any standard AR-15 lower receiver and comes complete with charging handle, forward assist, ejection port cover, A2 flash hider, bolt and bolt carrier assembly. Supplied without a rear sight, this upper is a great platform for a red dot sight or iron sights (both sold separately).
Note: Installation of AR-15 upper assemblies with certain features including, but not limited to: flash hiders, bayonet lugs, and threaded muzzles may violate state and/or local laws.
Use of steel-cased 7.62x39mm ammunition in the AR-15 platform may result in occasional light primer strikes due to the small diameter firing pin and hard military-style primers. Aftermarket triggers with lighter springs are not recommended.
