Barrel and BCG Kit

CMMG brought the first 4.6x30mm firearm to the U.S. civilian market. Now those that want to build their own 4.6x30mm AR15 from the ground up have everything they need. Combine the Barrel and BCG Kit with the mil-spec AR15 upper and handguard of your choice and all you will need after that is a standard AR15 lower receiver group and some of our 4.6x30mm Magazines and you re ready to roll!
