AR-9 Standard 9mm BCG (Glock, Colt, and MP5 Compatible)

  • US Made 8620 steel with nitride finish
  • Ramped carrier to work with both 9mm and standard AR hammers
  • Precision milled for use with Glock style, MP5 Style or traditional Colt style AR-9 lower receivers
  • 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.

**NOTE:  This BCG will not work if used in a standard 5.56 upper receiver with dust cover


The New Frontier Armory AR-9 9mm Bolt Carrier Group is proudly MADE IN THE USA by hard-working American men and women.
