Well I checked the nozzle, and it does indeed move. I'm not fully sure if it is moving correctly though. I was under the impression that after every shot, the nozzle should sit fully forward, however, when I shoot in semi the nozzle ends up part way back for about 90% of the shots, and only occasionally will go forward. Is this normal?
I also tried to look at the hop-up, but I don't have the right size screw drivers so I can't remove it.
