...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.

Never fails April 2, 2014
Reviewer: Christopher Lee from Newberg, OR United States  
This BCG is rock solid.  Properly staked key, MPI/HP tested, what more do you want?  I haven't had any issues with it yet.

Best bolt/carrier period February 21, 2014
Reviewer: Christopher Anderson from Annapolis, MD United States  
I have seen and used other mil spec BCG but they just don't have the track record like bravo company does. Definitely the favorite part of my rifle and will choose no other company.

Great BCG. January 17, 2014
Reviewer: T. Hall from Elkhart, IN United States  
I ordered my BCG on Tuesday, New Years Eve, and received it on Saturday. It shipped fast! All is well and I have no complaints whatsoever. I'm replacing my RRA carrier group with the BCM and putting the RRA in a new varmint build I'm putting together. Great product and I can't wait to put a few hundred rounds through it tomorrow!
