Cyma cm 030 glock

[snuff]

Cyma cm030 aep.
Pretty happy with this,apart from the FPS (easily solved)..but more worrying/annoying is that bb's roll out of the end then it missfires..so I fire one,tilt the gun the next one rolls out and the gun missfires...I know don't tilt the gun...,if I just fire with it level the second ball falls well short of the first and this continues..
Any ideas or help would be appreciated,thanks.
