Has anyone changed out the seals in their Matchguns MG1H? I hadn't shot mine in a couple of years due to severe joint problems, but now that those have cleared up my MG1H won't hold pressure. Rather than starting with contacting Matchguns, I thought I'd ask whether anyone here had replaced the seals on one before. Given the ever-interesting engineering of their products this could be either a nightmare or the height of simplicity (assuming the former).

Thanks in advance.

you can study the exploded diagram.

from what i see most of the orings are accessible but the manual does not state sizes and construction material
