Spare parts

[Guest tekeshi]

New to the forum, got back into the BB scene, so basically I bought two spares or repair WELL-G292 pistols and they both have the same problem soon as you load the co2 an screw it in they just leak badly, iv opened them up had a good look can't see anything obvious, only thing I did find was the co2 release valve was sticking open assumed that was the problem so iv took the part that was sticking shaved it down got it moving freely valve opens and closes as it should when the trigger is pulled, sorted but no still leaks from somewhere so instead of getting frustrated about it I basically want to know if it's possible to buy a complete gas chamber unit? Or my other thought was to swap the inners out of the slightly less powerful plastic version an put them in the metal frame, thanks for your time
