9mm Bolt Carrier Group BCG Nickel Boron 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. See fifth product picture for reference and click on the link below about this issue.

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.
