I am new to AR's. I purchased a DTech upper and built a lower. I used the DMR trigger but I am having an issue and I a don't know if the trigger is just out of adjustment or if that is how the trigger functions. I can feel no second stage. I don't have a lot of history with two-stage triggers but the ones I have used had a noticeable "wall". I cant tell that this one hits a wall at all. I would say about half my shots go off a little unexpectedly. I adjusted the weight adjustment screw for the second stage and could not tell a difference. I have no trigger scale. Any help here would be appreciated.
