I just replaced alot of parts in the upper gear box portion... now all the bb is doing is rolling out of my gun.

I replaced the spring, spring guide, piston, piston head, the front part of the the gearbox that connects to the tappet plate.

I dont know whats wrong with it. Everything is in an excellent condition nothing broke. Could it be that the cylinder which has two holes on the side is letting out air? Because those two holes are facing outwards.

Thanks all for help.

When i shoot I Hear this cling could it be that the bb's are hitting the tightbore b4 its escaping the barrel? The aircompression is that strong even though i changed it to a Prometheus s100 (330-350 fps).
