CMMG Radial Delayed Blowback 5.7 x 28mm BCG and 5" Barrel Combo


CMMG's patented Delayed Blowback 5.7 x 28mm system substantially reduces recoil compared to standard blowback 5.7 or AR57 builds.

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.
