They make the rings you are talking about. You should be able to get them with one extension and one standard or even two extended rings. I have never used the burris rings but I get the set-up you are refering to in Millet rings all the time. You may have to call Midway and talk to them so they know for sure what you want. I have run into the need for them scoping those long action Savage rifles with shorter scopes. Good luck. Cabelas would have them as well.
