I just built up a PSA lower with a PSA LPK with ACT trigger. When I tried to install the safety selector it wouldn't clear the rear of the trigger. I had to remove the hammer to get the rear of the trigger to depress enough to install the selector. It then went together fine and the selector doesn't rub on the trigger when I going to safe like on my other ACT lower.
I got this LPK/ACT last week so it is probably new production.
Anyone else have this issue? Could it lead to a problem?
