Nickel Boron has proven itself to be the most durable finish on the market. It's so good that it's being adopted by the Military and many Government agencies. It will never chip, peal, or flake off. It's much smoother than Hard Chrome, it's easier to clean and you can run it almost lube free for thousands of rounds due to it's self lubricating properties. These BCG's are a huge improvement over a Phosphated and Chrome BCGs.
