DESCRIPTION
 
M16 BOLT CARRIER GROUP 5.56 & 300 BLACKOUT BCG - HYBRID GOLD TITANIUM NITRIDE (TiN)

We decided to carry a quality BCG in a TiN coating that is more cost effective. The way we did this is by only coating the carrier in TiN. The other parts are Melonite Nitride treated. We also chose a more cost effective polishing treatment. The result is an affordable, quality BCG that looks like other BCG's that cost twice as much! If you're looking for a perfect, "Grade A" BCG, check out our Radiant version.

5 of 5 The man with the golden BCG January 16, 2026
: Ben F from Orlando, FL United States  
Very happy with the BCG overall. It is my second one from Mas defense. Might buy the radiant gold one next time for even more bling.
If only to nitpick I do wish on the bolt it was marked like the other one I bought for them, and the staking on the gas key was a little less than I like, but other than that, very happy with it. It currently lives in my MK 18 clone.
