Matching scopes and rings to get the lowest mount possible has always been a gray area for me. Especially if you are ordering one or the other. Usually you can take your rifle in to your local gun shope and they will help you fit a set of mounts from what they have on hand. I had a guy try four ring mounts on my 22 til he found a set that was tall enough. Had I order those rings I would have wasted alot time and money trying to get the right ones.
