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.
