Blitzkrieg AR-15 Full Auto Bolt Carrier Group
The Blitzkrieg AR-15 Full Auto Bolt Carrier Group is a Black Nitride coated Mil-Spec BCG designed for use with 5.56 NATO, .223 Remington, and .300 AAC Blackout ammunition.
Black Nitride coating is a process that hardens the surface of steel while also giving it high corrosion resistance, wear resistance, and lubricity. Our BCG is constructed with mil-spec parts to ensure proper fitment and function, all parts are machined and are not manufactured with any MIM (Metal Injection Molding) processes.
Our BCGs are coated by H&M who own the trademark “Black Nitride.” All parts are proudly manufactured right here in the USA.
