CMMG Radial Delayed Blowback Bolt Kit AR-15 Pistol 9mm Luger 8″ Barrel Nitride
Product Description
The CMMG MkG GUARD Barrel and BCG Kit allow you to build a Pistol Caliber Carbine using the Patent Pending Radial Delayed Blowback System. Unlike typical direct blowback systems, this 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. CMMG MkG Barrel and Bolt Kits are designed to work exclusively with CMMG MkG Lowers, and a mil-spec upper receiver with enlarged ejection port. Other manufacturers’ receivers may work, but we cannot guarantee function or reliability.
Features
- Salt Bath Nitride Finish inside and out
- Radial Delayed Blowback Bolt (Patent Pending)
- Requires enlarged ejection port for reliable operation
