The CMMG Replacement Barrel Kit 9mm Luger 8" Black Nitride Chrome Moly Fits AR-15 is available at Nautilus Arms. Key specs: Steel Aluminum construction and Salt Bath Nitride finish.
CMMG's 9mm Barrel and BCG Kit allow you to build a Pistol Caliber Carbine using CMMG's Patent Pending Radial Delayed Blowback System. Unlike typical direct blowback systems, 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. Their Barrel and Bolt Kits are designed to work exclusively with mil-spec AR-15 upper receivers with a modified ejection port, like their MkG/MkGs upper, and most mil-spec AR15 lowers when used with 9 AR Conversion mags as well as their MkGs Mk17 and Mk9 lowers. Other manufacturers receivers may work, but we cannot guarantee function or reliability. Older Mk9 lowers will require one of their retrofit kits to convert it to a Radial Delayed Blowback compatible lower, instead of Traditional Blowback.
