Written by Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE), Chief of the Firearms Technology Branch
...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.

    BCM BCG

    Bravo Company makes an excellent product. I've been a customer for 7 years and their products are a staple in all of my AR15s.

    Beautiful BCG

    The fit and finish on this bcg is amazing. The gas key has strong stake marks. The machine work on the carrier and bolt itself is amazing. If you're looking for a bcg that you can depend on with your life, then get it. I chose this group for my personal defense rifle.

    Amazing

    Finally finished up my 300 BLK build and got to run this superb BCG this past weekend. Outdoor shooting and training in humid weather turned to a full-on downpour. Our instructor kept us out, as he should have. Zero malfunctions despite the weather and challenging elements. This should be everyone's go-to BCG for 5.56/300 BLK.

    This is an excellent, reliable BCG. When I build another AR, I will defiantly purchase another one just like this one.

    Just what was needed.

    I purchased the Bolt Carrier Group to replace one in a brand new Ruger AR556. I was not impressed with the unshrouded firing pin setup that Ruger decided to go with. I'm happy to say Bravo Company had just what was needed for an excellent price. The BCG runs flawlessly. Thank you Bravo Company for your attention to detail and your dedication to the customer even after the sale.
