...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.

    Excellent quality and durability. Both the you bolt carrier group and QRF 12 mid length upper created a more than reliable, and consistent soft shooter. Without a doubt, BCM will have my return business and recommendation to anyone.

    BCM BCG

    After using many cheaper BCG's throughout my years, I now only use BCM bolt carrier groups. The AR is only as reliable as the sum of the parts and the knowledge to properly assemble. BCM is quality you can virtually bet your life on and BCM bolt carrier groups have never failed me. If reliability, dependability and function is your goal, "then I can without hesitation" recommend BCM bolt carrier groups. Yea, they are that good!

    Bolt carrier group

    I've been using bolt carrier groups from Brovo company in all of my ar builds for years. I've never had any issues with the materials used or the workmanship, which have always been of a high quality. I would recommend Bravo company for their quality built components and fast shipping.

    Quality Product

    I bought this as an emergency replacement for my AR. I was very surprised to compare this with the commercial bolt I was running in my AR. What a difference, I am now considering purchasing another one for a spare and shelving the commercial BCG. This is real quality. Hats off to Bravo Company keep it up I have become a loyal customer.

    ExcellentProduct

    Bolt Carrier Group ordering was easy. Unit shipped right away and arrived on time. Unit was complete and new as described. Installed easily and performed perfectly with different brands and grain ammo. Cost a little more for this quality, but can you really afford to install junk and then have to buy a quality BCG later? I would highly recommend this product!
