AR-40 .40 S&W / 10mm Bolt Carrier Group - BCG

  • US Made 8620 steel with black nitride finish
  • Ramped carrier to work with both 9mm and standard AR hammers
  • Precision milled for use with Glock style 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)
  • This bolt can also be used in a large frame lower to run 10mm

**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-40 .40 S&W Bolt Carrier Group is proudly MADE IN THE USA by hard working American men and women.

    Mine runs flawlessly as well, but only use with a standard barrel, not a ramp barrel, mine wouldn't work properly

    Got this about a year ago for a 16" barrel AR platform in 40 S&W. Finally was able to get a 10mm 16" barrel from here to use this bcg. The 40 S&W platform has run flawlessly.
