I thought gun control was bad here in America. I read on this forum in another post, some one else said that he had to do the same go from one country to another because of the same laws. Is it Hungarian I think? I remember Belgium is where he had to go to enjoy his Air soft replicas. I had the same thing happen to my Dragonov. There is a grub screw closest to the air nozzle on the hop up chamber, I had tightened it to far and had a feeding problem and the air nozzle didn't seat all of the way chopped a bb also, and it jammed (grape flavored) the piston, I don't know if that will help as far as a place to look.
