Well, I guess it was probably inevitable - but my Gauntlet has developed a leak. I'm thinking it's probably due to the exclusively CO2 diet I've been feeding it? I've been using pretty good "shot control" (pausing a loooong time between shots due to temperature effects of the CO2 vaporizing), but have also read the O-rings don't dig the CO2 too much, so I'm thinking that's probably the deal.
Anyway, it leaks when I chamber a pellet (so it's not the tank, in other words). Not a huge whooshing sound - but loud enough to know for sure there's a leak. Any suggestions on where I should look and what size O-rings I should stock up on? Never torn one of these (or any airgun) down before, so it's a tad intimidating - but the ball and chain wife is out of town right now so I want to get my shoot on! 8)
Thanks in advance!

Chambering a pellet cannot cause the leak,try to open the bolt with a pellet chambered and the magazine out,probably the leak come from the valve poppet and you will notice the gas escape from the breech when the barrell is obstructed by a pellet.

Here you go

Agree...very likely a leak from an open bolt (or from the muzzle with the bolt closed) is caused by the valve stem seal (poppet). Could be fouled and be cleaned back to health, could be sliced and diced by stray grit/debris and need replacement.
Not really sure co2 would be a cause, other than industtial/paintball co2 generally being a little more "dirty" than compressed air.
Matyerial that makes the valve seal (usually a form of Delrin) is the same for either gas and not going to interact with it in a harmful way.

Thanks everyone. You're right about chambering a pellet not being the problem - I left the bolt closed overnight and the CO2 tank was empty this morning. So, even though I couldn't hear it, it was obviously leaking. Got a refill today, so I'll try your suggestions later.
