AR-45 Standard 45 ACP BCG

• US Made 8620 steel with nitride finish
• Precision milled for use with Glock or Colt style magazine fed lower receivers
• M-16 cut for use in transferable full-auto MGs, dealer post sample MGs 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.

**A small amount of Loctite is recommended on the set screw that holds the BCG weight in place. 

The New Frontier Armory AR-45 Bolt Carrier Group is proudly MADE IN THE USA by hard working American men and women.
