Would be easy to show you but difficult explain. If you're unfamiliar with that ring and base system (Leupold QR) the rings affix to the bases via a round stud into a round hole with a cammed cross pin to lock it in. The individual rings, without being clamped to a scope, will slide in and out of the bases smoothly. On my particular rifle, with a scope mounted in the rings, the studs bind up in the base's holes making removal & replacement of the scope/rings difficult. That makes me think that either the scope bases (two piece) are not mounted parallel with each other or the rings are not bored square with the studs.
Hope that makes a little more sense?
