A number of people here own them and other than a few minor problems, I think the biggest complaint I heard was from Alstone who got one that had metal shavings in the valve- apparently the factory clean-up on that one wasn't good which caused the valve to jam and the gun not to operate. All the same sort of mods that can be done to any Co² gun can be done to a QB78- and I believe there is at least one "kit" available out there to turn it into a PCP with a higher-flow valve assembly and a reservoir. As for you other questions- I don't own one- so hopefully someone else can fill you in. I believe these questions have come up before- so look in the Rifles section for posts on the QB78 and you should find more good info. _________________ ` I'd say "I care." But I'd be lying.

The QB is one of the roughest built guns I have ever bought, but after a bit of cleaning, smoothing moving parts off and a good lube it is one of the best guns for general use I have ever had, all problems can be fixed with simple tools and they are easy to do, also there are simply hundreds of spares, kits and upgrades for it plus plenty of sites catering for it. If you had to buy one Co2 gun to play around with you cannot better a QB.
