Badass BCG
I've purchased a few of these Bolt Carrier Group from Modern Armory. I shot the shit out of them unsuppressed and suppressed, still holding strong . One of the BCG's has over 5,000 rds and still going strong.

Worth Every Penny
This bcg is worth every penny and many more, I love the C158 bolt and Sprinco springs. So far only 1k rounds on it but this thing is a beast. Thanks again Modern Armory for the great CS.

Great Bolt Carrier Group
I purchased this a few months back and haven't had a single problem, shot about 500 rds and slight finish wear but that could be lack of lube. Love the products on here and it is always great to talk with Don.

Great BCG!
We run Modern Armory BCG’s in one of our 10.5” Post sample, suppressed, machine guns. This BCG gets ran hard & cycles like a dream. Great staking, great components & no questioning it’s quality. Will definitely be adding more to our collection.
