I tried with different paint Empire hot box, valken infinity, field brown box, jt paint and stinger paint. It looks like is on the breach, use to got a lot of blow back and I change "o" rings and is better but still chopping ball and it don't matter if is on semi or full auto. I change the barrel thinking that will help but it didn't. Change the detent and is a lot better. I don't know if I need to change the bolt or the antichop spring. Also change velocity spring first was at 347 fps now is at 285 fps and I run out of ideas, thanks for your time and help.
