    Black Ops problem

    I reseal a lot of CO2 pistols but having problems with a Black Ops revolver. Fitted a complete new seal kit but gas is dumping down the barrel. Even fitted a stronger valve spring to hold valve shut. The replacement blue valve seal seems rather hard, not urethane or Teflon, seems to be nylon. Anyone had similar leak problems ? Looks like they use the same valve as the Dan Wesson.

    Made a new valve seal from 90 Shore A polyurethane, but still dumping gas. This is very unusual problem I can't figure out.

    Is it upon first firing, or as soon as you pierce the cartridge?
    Could there be a piece of debris in the valve?
    Good deals with these members

    Soon as capsule is pierced it all dumps down the barrel as if the valve is permanently open. Had it to bits about 8 times, it is very clean inside the valve chamber.

    Have you tried gassing up when the hammer is cocked so that it isn't resting on the valve pin?

    Did try that as the first option, but the hammer/ transfer bar does not press on the valve pin on these in the rest position. Sits slightly back, so that gas does not leak out when pressure gets low.
