welshwarrior Posted May 10, 2010 Report Share Posted May 10, 2010 I have just got back from 6 months away, I left my QB78 in the cupboard. When I just got back I changed the capsules and it seemed fine when I fired the 1st pellet the CO2 all rushed out of the barrel. What wrong with it and can I fix it? Please help I want to kill off some of the rats. Quote Link to comment Share on other sites More sharing options...

WW Most Shops that Stock CO2 Gun's Should Stock it - it's Silcon Base Keeps Seals Lubed - Comes in Spray and Drip Bottles SMK's do their own bottles .

brian45 Posted May 11, 2010 Report Share Posted May 11, 2010 Worked for abit then vented again. if its going up the barrel its your valve stem that sticking or the head of the valve is loose, take the action out of the stock remove the triger you should see the valve stem inside, give it a push to see if its sticking, if you go to the site i posted you will be able to get new seals for your qb Quote Link to comment Share on other sites More sharing options...
