DESCRIPTION
 
AR-15 BOLT CARRIER GROUP 5.56 & 300 BLACKOUT BCG - NICKEL BORON

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.

I ordered this Nickel Boron BCG for a custom .300 BLK pistol build and I'm very pleased with the product. MAS Defense filled my order quickly and it was delivered within days. The price was the best I could find anywhere. Thanks!
