Toolcraft 5.56 NATO Black Nitride Bolt Carrier Group – Left Hand

Simply the best left-handed 5.56 NATO bolt carrier group on the market!

Toolcraft 5.56 NATO Black Nitride Bolt Carrier Group is a Full-Auto M16 BCG manufactured using the finest U.S-sourced raw materials. 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 BCGs.

When you want one of the best-looking and performing Bolt Carrier Groups available today, choose a Toolcraft.
