Hi guys. I just wrote a post earlier about my plans for memorial day weekend. Im going to be doing a lot of shooting. I figured i would bring up all my airguns. I haven't shot my big bore in a long time due to the fact it was leaking air and i hated pumping it up with the hand pump. But now i got the compressor so i figured i would replace a few o-rings and see if that would fix the issue. The gun is a Shinsung career dragon slayer in 50 cal. Ive had the gun about 9 years or so. I took it apart and i looked in the air reservoir and i see 2 small white stains. It turns out after closer inspection with a flashlight that the metal had pitted pretty deep. Now this makes me a little nervous being it will be under 3000 psi. Do you think the gun is garbage now or does anyone have a suggestion? Also this was not where the air was leaking. But Im guessing it could blow out.
