G3 not Firing

[Nish]

Shot one ball low over the chrono. After that all I get when I pull the trigger is the tiniest puff of air from the grip frame. I've tried battery, and checked the solenoid orings but everything seemed fine. Suggestions?

Have you had any similar problem previously? This is a problem that can come creeping on a G3, but seem to go away for the day after you've gotten it to properly fire again.
The o-rings on the bolt does get stiffer over time. Eventually they will be so stiff that they will affect the G3 in this way. You won't be able to tell neither by look, nor by feel.

A change of all three o-rings on the bolt will most probably solve the problem, provided you've already switched to new batteries twice, and eliminated the HPR as a source of the problem.

DP G3?
I had a similar issue, and it turned out to be one of the bolt orings. The one on the shoulder i think...

Didn't even occured to me to check the bolt rings.

I will try that next.

This is the first time that I have had the issue, I did make sure it had grease on the bolt but it's been in storage... Maybe 2 years.

Thanks for the suggestions guys I will report back once I get a chance to change them out

It's this one here (or at least it was for me). This oring being bad and leaking-by created kind of a bolt lock up, IIRC, and kept the bolt from cycling.
If you don't have a fresh oring, I think the one on the bolt tail piece is the same size. You could try swapping it and see if your problem changes to a leak-down-the-barrel...?

[Olsson]

Once they've gotten stiff enough, grease won't help. So don't make the mistake to dismiss the o-rings as the culprits after you've greased them, and the problem persists. Trust me - I know from experience...

On Rainmaker's picture, there is an o-ring inside the body. You might as well replace that one as well, when you're replacing the bolt o-rings, since that o-ring also causes drag on the bolt. However - you might also want to replace the bolt o-rings first, to see if the problem goes away. The o-ring in the body is a real pita to get back into place. Or possibly I was not smart enough to do it the easy way.

I have a full set of orings for it I might just replace all of them.

So I have 2 bolts/backs for this gun. I didn't know that but when I got into the parts box for it looking for the orings I found it. 1 works. The one that wasn't in it works. The one that was in it I changed out some orings and apparently I got the wrong center bolt oring on it because as I was running out of time to work on it it was not recocking all the way. Seems like the oring I put on the center isn't right. It's not staying in place. Going to have to try again. But the stock bold and back work.
