I bought the original nexus lower when they first came out. Also the rise armament 140 trigger, and atrius super selektor. Everything worked fine for a bit then the plastic trip broke. So i got the new metal one. Now the gun only works in super safe. In semi, It will fire 1 round, chamber the next but wont fire the next round without me charging the handle. It seems that it isnt resetting the trigger maybe in semi? Im not a gun expert so idk how to proceed. Any help is appreciated on how to move forward.
