Scored a PGP

[VintageZoomer]

Well, I aired it up and it leaked out in seconds. Evidently the seals must be fried. Here's the photos. I guess I have the round valve cause it pushed out easily. Looks like the 12g seal is pretty crusty. Guessing that's where it leaked.

So I just need a phantom cup seal and a couple of rings then? Seems pretty simple

Exactly,just a couple o-rings and a Phantom Cupseal and you're good to go.... You can refurb the Sheridan Cupseal with a drill, toothpaste and an old toothbrush

Pro tip: Mark the two halves of the valve before opening it up to ensure the two sides line up properly when you reassemble it.

Did not know the cartridge valve would come apart. Good to know.

I got ahold of a Palmer's seal kit with the dynavalve. Aired it up to check for leaks, but didn't have any paintballs. None in stock unless I drive an hour. I had to shoot a good number of times to run out of air, so I'd say the leaks are gone.
