  • M-16 cut for use in transferable full auto MG’s, dealer post sample MG’s or other legal machine guns (ALL BATFE RULES APPLY)

**NOTE:  Many Aftermarket drop in triggers use modified hammers which may not reset properly, or hit the firing pin square on the carrier which could cause firing pins to bind and snap.  We recommend using only MILSPEC hammers with any 9mm, .40, or .45 blowback bolt carrier groups.
