DESCRIPTION
 
M16 BOLT CARRIER GROUP 5.56 & 300 BLACKOUT BCG - HYBRID 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.

5 of 5 Nickel-Boron BCG November 29, 2022
: Turner from DAVIDSONVILLE , MD United States  
I cracked the cheap PSA bolt I bought when I built my AR and needed a replacement. I decided I wanted a Nickel-Boron coated BCG after reading about them, and after I shopped around I found the one offered by MAS Defense. It dropped right in without issue, I've put about 200 rounds through it last weekend and it functions flawlessly. I'll be replacing my other rifle BCG with one of these in the near future.
