I just picked up a Leupold VX-II and found the tube to be shorter than my old Bushnell Legend. I have a long action Savage and find that the rings are too far apart for the shorter tube. Not being knowledgable with scopes and mounts, I'm wondering what the best route would be to take. What would be a better mount...a pictinny style one piece mount with my current Weaver style rings or should I go with extension rings? I have no idea what would be the more reliable/solid option.
