Well, i have opened the upper gear box, disassembly the inner barrel, checked the rubber in the hopup, all seems to be ok, all is at the right place and well aligned.
After the reassembly, with the hopup at neutral, the gun is firing right and now seems to be firing straight and not on the right BUT if i try to adjust the hopup i have some missfired, sometimes shoot 2 bbs at a time and sometimes the bbs are just dropping from the barrel...
So i guess the problem is from the hopup, i'm thinking to change the rubber, do you have other ideas ?
Thks guys
