Sourcing O rings wasn't that easy, some just don't like Co2, but my local suppliers BSL Walsall managed to offer several choices of material, for all but one ring which is a 1.2 mm section; which they don't stock. It seems metric O rings are not at all straight forward, some countries use different increments ??!!
Anyway success, the O rings worked ok; lost count of the hours involved; no profit after buying O rings, but satisfaction by the bucket load. More important, a gun still in use.
ha, I had one of those pistols some years back that did exactly the same thing.Whoosh and all the gas came out of the barrel at once. had a bit of a shock. Id no idea about how to try and fix it, so sent it to Armex who were the umarex agents. When it came back from them having had a new valve fitted it still had the fault so back it went to them. 2nd time it seemed to be fixed, but I'd lost confidence in it so sold it whilst all was Ok
