does the bottom of your Faxon PCC BCG have a bump on the bottom of the pick-up lug, as shown on the front-most in this pic? that bump serves to push down on the hammer so that it goes deep enough to reset.
usually the BCG mfrs party line is that their stuff works with USGI mil-spec, and as soon as you deviate from that (e.g. Larue MBT2 trigger), all bets are off. Trigger mfrs probably say the same thing, their triggers are guaranteed to work with a USGI mil-spec 5.56 BCG, anything other than that, buddy, you're on your own.
