I'm gonna keep this all in the same thread cause it's still yet another problem with the same gun. My gun gets stuck on semi at times. Meaning after several shots it just wont fire unless I put it on auto fire then back to semi. Again at first I thought it was something I did, But I've seen two videos on u-tube with two guys having the same problem right from the box. I never fired this gun in it's original state ,So I wasn't aware of this til after I changed everything,Apparentaly this time it's not me. I was thinking of just replacing the whole trigger/wire harness unless I can get a better answer to the problem. After 4 or 5 shots the trigger sticks like I put the safety on.
