**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.

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.
