I acquired this old PGP Paintball gun several years back. When I got it, it shot well, very well. I somehow lost the seal that sits where the CO2 chamber gets pierced, so I put it away for about 5 years. I finally went to the local Army Surplus store today and the owner was able to find me a seal (Green Beret in McAllen Tx., if you need special parts, talk to the owner) Put seal in, but still leaks. Anyone here have experience with these? There is not much out on the 'net that's been helpful...
