It’s much smoother than Hard Chrome, it’s easier to clean, makes the rifle cycle smoother, it can be run almost lube free for thousands of rounds, and it will never chip, peal, or flake off! Because of these benefits, Nickel Boron is being adopted by the Military as well as many Government agencies. As you can see, these BCGs are a huge improvement over a standard Phosphate BCG and it’s even an improvement over Hard Chrome.
