I have a Stag Arms lower with a 20" SS HB flat top upper on it. It has a RRA 2 stage NM trigger in it. I was having some issues with the gas system and finally got that worked out and went to test the rifle today. I loaded the mag with 3 rounds and the hammer wants to follow. I took the gun apart and checked everything and it all seemed fine. I loaded 3 more rounds and tried again, same thing. Disgusted I took it apart again. It looks as if there is very little sear engagement and the hammer just wants to follow. I seem to vaguely recall that the RRA NM 2 stage triggers had some issues a while back but can't recall the exact circumstances. I've had the lower for a couple years and put the upper on it last year. I tried to get it to work then but it would fire once and then the hammer would fall on an empty chamber. Got frustrated and put it in the safe. Seems as is the gas block was 30 thousandths off and it was not getting enough of a gas pulse to function correctly. Gas system seems to work ok now but the hammer wants to follow. Any thoughts from you AR experts?
