NEW FRONTIER BOLT CARRIER AR-9 9MM BLACK
FEATURES
-Caliber: 9mm
-Glock & Colt Compatible
**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.
**NOTE: This BCG will not work if used in a standard 5.56 upper receiver with dust cover
