APS II BB's Rolling out...
 

I took it out to a game and noticed that the hop up was engaged way too much but saw no external adjustments. So afterwards I took it home and took it apart. I disengaged the hop up completely. But now when I cock the gun, BB's just roll out of the barrel. Oh and when I tried to engage the hop up again the hop up rubber won't stay put. If you have any idea what would fix this let me know.

Thanks,
