DESCRIPTION
 
AR15 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.

4 of 5 BCG July 30, 2020
: Erick McFarland from Charlotte , NC United States  
Came assembled as apart of a completed upper I purchased. Haven't fired the firearm yet but it seems to function as it should.

5 of 5 Great Look and Finish July 20, 2020
: K Geisler from Rockford, IL United States  
Though the overall look and finish are appealing, the tight, precise operation and ease of cleaning compared to other BCG's I've used make it even better.
