Just tagging onto this thread, but........

My Mk2 has an issue where the scope rail is out of line with the barrel. The barrel is straight, the main body tube is straight, but the breech just isn't in line. It's not glaringly obvious and its only after zeroing and finding the pellets striking out to the right the further out you shoot that makes it apparent.
The gun is flawless in every other respect and the stock has been beautifully restored, but I'm pulling my hair out with this issue.

Can I get a mount thats adjustable for windage? I just want to get it sorted before I inevitably sell it!
