5.56 NATO BLACK NITRIDE BOLT CARRIER GROUP
Simply the best 5.56 NATO bolt carrier group on the market! Available in either 9310 or C158 Steel Bolt.
Toolcraft 5.56 NATO Black Nitride Bolt Carrier Group is a Full-Auto M16 BCG, manufactured using the finest U.S sourced raw materials available. The Black Nitride coating vastly increases the hardness of the steel, prevents corrosion, is highly resistant to wear, will not flake (it’s not a coating, it’s a bond), and has increased lubricity when compared to a phosphate finished BCG. The Bolt Carrier Group is the heart of your rifle, and if you want to upgrade the functionality of your rifle, this is a great way to do it! If you’re after the newest high-performance BCG finish, ensure you take a look at the DLC Coated BCG’s.
