...M16 bolt carriers are not designed and intended solely and exclusively for use in converting a weapon into a machinegun and are not any combination of parts from which a machinegun can be assembled. Further, an M16 bolt carrier is not a firearm as defined in the GCA or a machinegun as defined in the NFA. An M16 bolt carrier is simply a machinegun part and as such its domestic sale and possession is unregulated under the Federal firearms laws. It is not unlawful to utilize a M16 machinegun bolt carrier in a semiautomatic AR15 type rifle.

    Bolt Carrier group work's as expected. Slightly reduced the recoil with the added weight. Loving the BCM logo on the bolt. Excellent product and fast shipping.

    Bulletproof

    BCG is great! I have used these items on at least four other builds and all have worked perfectly. The rifles I have put together are for extreme use. I highly recommend Bravo Company for quality and good service.

    This is my 2nd time purchasing this item. You guys have an awesome shipping and processing dept. Each order arrived quickly. I have yet to test them out by I have absolutely no worries about your products. Looking forward to seeing how they run though.

    Everything was absolutely perfect.

    In a world where I don’t expect much, it was nice getting my order exceptionally fast. Great packaging too (that the spares will stay in).

    The BCG is a work of art that functions flawlessly. I show off wherever I can wh’ip open the case, and it’s not only the “ohhs and ahhs” that are impressive, but the way women seem to want to pump their hind ends like those gals in the black rapping musical videos when they see it - and I’m not even all that attractive so I know it’s the BGC causing this.

    It screams “toxic masculinity” without actually screaming it, but there’s balance now that I feel as though my chakras have been aligned by purchasing this!

    Best BCG I bought

    Good Quality. Will defiantly purchase it again for my next built. I recommend it buying if you're already purchasing an upper from this site.
