Have you tried that well trigger box with the shs sears?
I would venture a guess that shs used a clone to fit their sears so when you are tryin to put em in a trigger mech with a tighter fit something is sticking.
what about adjusting the length of pull and trigger weight adjustments, have you tried that?
Again i suggest just buying a set of deepfire (about 50 bucks) and be done with it. Or start looking for what is catching ans start modding the sear to mesh propperly (not worth the time imo)
