[Strike1090]

Hey, my uncle just recieved a used spider, an old model Java edition. There is an air leak when the c02 tank is screwed into the adapter. We checked the O-rings in the expansion chamber and they all seem to be intact and ideas as to why the gun is still leaking?

 

[sgt.slaughter]

The cup seal may have to be replaced, or the o-rings on the valve, alot of people make the mistake of checking the o rings first when the o rings dont really do much unless the ones on the striker are worn because that the one that help with the air.

also where is the leak coming from?
