So, I just got a used G5 today and it had a minor leak down the barrel. I replaced the two bolt orings and the gray back cap oring and the leak persists, although it's not as bad. I'm using TechT Gun Sav for lube. These are the only things I can think to do next...
- let it sit for a few days, then try again
- air it up and let it sit
- use dow 55 to swell the orings a bit
Do any of these make sense? Did I miss something?
FYI: There is almost no resistance when putting the back cap in the bolt - it slides on and off as though it's hardly touching.
