CMMG is known throughout the firearms industry as a premier manufacturer of AR parts and accessories and complete Bolt Carrier Group is no exception to that rule. This 9mm Luger AR-15 bolt carrier group is specifically for individuals who are utilizing the 9mm Luger platform in either their AR-15 upper assembly or their CMMG Mk9 platform. The benefit of this carrier is that it features a special cut that allows you to utilize a lower which feeds from GLOCK and traditional COLT SMG 9mm Luger magazines. This 9mm bolt carrier group is the perfect piece for your next build or as a replacement for an inferior bolt carrier group.

Want to get in on the pistol-caliber carbine craze without having to load your AR up with special components? The CMMG 9mm Enhanced Bolt Carrier Group is designed to use all the components in a standard AR-15 lower receiver, making conversion fast and easy. Unlike other options on the market, the CMMG 9mm Enhanced Bolt Carrier Group can function with the standard 5.56 NATO hammer, removing the need of the user to install a purpose-built 9mm hammer for use with a 9mm carbine upper receiver. Each CMMG 9mm Enhanced Bolt Carrier Group is machined from quality ordnance steel and is a single-piece design that enhances durability and strength. The carrier key is staked, and the entire assembly is compatible with both Colt-style magazines and Glock pistol magazines.
