Tobyb525 Posted January 12, 2009 Report Share Posted January 12, 2009 In CO2 guns there is a seal that can need replacing after a while. Take it to a gunsmith and they should be able to replace it. Toby Quote Link to comment Share on other sites More sharing options...

bruno22rf Posted January 12, 2009 Report Share Posted January 12, 2009 hi-the gun must be under warranty so any decent dealer should replace the seal free (easy job)-it might pay you to check the tops of your co2 capsules by running your finger round them to check for dents/sharp burrs before you use them-once you are up and running try to avoid leaving a charged capsule in the gun for long periods (say 2 weeks or more) as this puts the seal under constant strain-bruno.

tbeagley Posted January 17, 2009 Report Share Posted January 17, 2009 Hi, i have a QB 78 (co2) that i have to screw up tight, then fire it to pierce the bulbs. If not, unscrew 1/2 turn to release pressure into the chamber. Screw it in,fire it, then unscrew it. It should stop hissing almost imediately. Cheers, Terry.
