Well hell! theres your problem. it should move 1/8 -1/4 of an inch for a1/2 barrel
yer so make your piston a bit snugglier with the housing (use electrical tape, duct tape tends to grab), put some washers or a spacer of some kind behind the piston to stop it moving so far back.
chaos, how did you o-ring your piston? i dont think you could put a groove in a washer piston like yours?

yer it uses rubber disks about 8mm thick, it does the exatct same jobs as o-rings do, it was all i really had to work with at the time and i still dont have time to lathe a new one up.
