- Our AR57 Barrel And BCG Kit Allows You To Build A Pistol Caliber Carbine Using Our Patent Pending Radial Delayed Blowback System. Unlike Typical Direct Blowback Systems, Our RDB Uses A Bolt That Is Forced To Rotate And Unlock, Slowing The BCG. This Results In A Lighter BCG For A Lighter Rifle, And Less Felt Recoil Than A Straight Blowback System.
