...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.

    I have not run it yet, but am expecting the same durability/reliability others have experienced.

    BCM Top Notch Quality+Very Fast Shipping

    Ordered this bolt carrier group on 12/25, BCM shipped it on 12/26, and I received it today 12/28. The quality is top notch and shipping was super fast. I will definitely be buying a lot more things from BCM in the future!

    Finally got one!

    I was going to buy this for Christmas in 2012 but suddenly everything went out of stock due to the big scare. It wasn't until about 8 months later that I finally got to order one.

    It shipped really fast and people aren't kidding when they say Bravo ships fast and they ship quality product. I have a Bushmaster Modular Carbine and while my BCG was "staked" and appear to be in good condition, I felt I wanted the BCM one. Now I feel a heck of a lot better with a full auto m16 bcg in there and it drops in perfectly.

    Now one negative thing is that the picture here shows a slightly greenish color BCG. The one I got was black. Not that big of a deal but figure I'd say that in case anyone else decides to get one and think it's slightly green.

    Just right.

    Everything I purchase from Bravo Co must meet my standards, since it is my hard earned money paying for it. This BCM is no exception and it does meet my expectations. I installed it in a new build and it fit perfectly and performs exactly as expected.
