The original nozzle broke and has been replaced with a retroarms 19.6mm nozzle which is seemingly identical apart from a slightly smaller chamfer. The air compression parts are forming a solid seal and it even passes the paper test.

It shots at an inconsistent 110-200fps on an m110 spring. It shoots at 300fps when a 0.28bb is dropped into the feeding chamber and fired without the mag in. Has anyone had any experience with obtaining a consistent high fps with this gun? Or just mention what buckings they use?

Annoyingly enough I have only ever had this working well as a DSG and have not been able to replicate it. Right now its a SSG.
