I currently have a fully upgraded JG bar-10.
PDI cylinder
PDI bore up hard piston
Cylinder head
6.01 barrel
nineball soft hopup
It shoots around 550 fps

The problem i have is that it barelly shoots anywhere. I try messing with the hopup and it only affects it a little. itll shoot 130 ft then drop. I think its a problem with the hopup not working correctly. Please help with any suggestions

Yes metal spring guide. also what is an aero chamber. and that might be the problem because the bbs drop going at high fps. (velocity doesnt lower when they drop)

also how do i relign it
