I am looking for a local supplier of oring seal kit for the R10 Mk2, and can't seem to find anything. I did order from the UK, but that will take a minute to get here, so I'm still searching. Is there anywhere I can find a database of seal sizes for the R10? It seems BSA is much more secretive than any other airgun manufacturer with this knowledge. I don't mind the secretive nature, IF the kits are readily available where the gun is, but this seems to be the opposite. A lot of folks like to bash FX, but at least they list oring sizes right in their parts drawings, so kudos to them!!!
