Description
Chambered in .300 blk with a bloodline 16-inch Rosco Manufacturing heavy black nitride barrel with a 1:8 twist and a pistol-length gas system. This works on a normal carbine AR-15 lower. A great choice for hunting with your AR-15. It is light recoiling and cycles regular hunting ammunition well. We do not offer an adjustable gas block for the Commando because these are tailored to run subsonic and supersonic. We only suggest using this upper on a carbine style lower receiver.
All of our Upper Receivers work with standard AR-15 Lower Receivers
