MARK 2: POLECAT

Chambered in .300 blk with a bloodline 8.2-inch Rosco Manufacturing heavy black nitride barrel with a 1:7 twist and a pistol-length gas system. This is the perfect choice if you own a can and want to go from sub to super with a mag change. We do not offer an adjustable gas block for the polecat because these are tailored to run subsonic and supersonic. This 300 BLK is tailored to run heavy subsonic bullets with the 1:7 twist.
