So I wanted something small to shoot paintball size projectiles and to be manualy powered. I used T piece brass piston valve (common design), shortened shrader valve for trigger, and smallest bike pump i could find for power source. The rest are brass fittings, teflon tape, epoxy glue and PP pipe for barrel. Need to improve tightness and smoothness oof piston operation and will be able to shoot some 15 yards relatively straight with about 3bar pressure.

Welcome to the forum and nice work! I like the way you configured the pilot valve to act directly as a trigger, quite a neat setup.

Try to connect instead of the pump cylinder with Greengas. This can be done even with cold welding and electrical tape.
