Barrel And BCG Kit

Description

The Barrel and BCG Kit is perfect for building an AR pistol or SBR using CMMG’s patented Radial Delayed Blowback operating system. Unlike typical direct blowback systems, Radial Delayed Blowback not only reduces the weight in your BCG but it results in less felt recoil than a straight blowback system and still provides essential features like last round bolt hold open. CMMG’s Barrel and Bolt Kits are designed to be assembled into a Mk4/mil-spec AR15 upper.
