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 BCGs. They are even an improvement over Hard Chrome.

BCG Upgrade March 10, 2019
: Mike from Cincinnati, OH United States  
Wanted something more than the regular ol' BCG so I went with NiB this time.  Very smooth and not much oil needed to keep it going.  Highly recommended.
