9mm Bolt Carrier Group BCG NITRIDE for GLOCK and COLT Mags, Full Ramp
***Note: These BCG's require that a small amount of filing or machining on the bolt catch if used with CMMG style 9mm lowers as the CMMG style bolt catch interferes slightly with the bottom of the BCG when fully assembled causing the BCG to bind.

...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.
