Our barrels are made in the USA from solid bar stock, head spaced and are ready to assemble. The 10.5 .300BLK was the original design length for the Blackout platform. Giving both maneuverability and accuracy the .300 has much more knockdown power than the standard NATO 5.56. Originally built for military use, it has become very popular in the civilian market and is a perfect round for home defense and hunting. Gas port tuned for reliability with your AR15 300 Blackout rifle or pistol using either supersonic or subsonic .300 Blackout ammo.
