...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.

5 of 5 Slick and smooth April 20, 2019
Reviewer: Vanhuss from Tx  
This product is slick and smooth in both  appearance and function. The feel of the bolt is astounding. The look of the bcg when you charge it stands out, polished nickel on black always slaps a smile on my face. Cleaning this bolt is fast with just a simple wipe and reinstall, you are ready to play.
