AR-9 Modular 9mm BCG (Glock & Colt Compatible)

  • High quality US made steel with black oxide finish
  • Innovative two piece modular design for easy caliber and carrier weight changes and easy cleaning/maintenance
  • Uses standard AR-15 extractor and spring for increased reliability and more consistent ejection
  • Unique design provides an additional 2 oz of mass over most standard 9mm bolts enhancing operation
  • Ramped carrier to work with both 9mm and standard AR hammers
  • Precision milled for use with both Glock 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 blow back bolt carrier groups.

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