SKS Scout Scope Help

[gretsch6120]

I mounted a red dot scope much to the same that is in the picture I attached. I want to replace the red dot sight with a compact scope. I am looking for a scope with a magnification between 2-5x. Here is the issue I've been having; I haven't yet found a scope that I can mount far enough forward to the rear of the scope doesn't hang over the chamber. I would like to find one that I can mount flush with the rail or a little behind it. Any recommendations?
