eldequello, this burris ring you are referring to is the Burris Signature rings. It does help if the rings aren't lined up and also if you run out of windage on your horizontal or vertical as you can get an offset set that will raise or lower either one or both ends of the scope to avoid having to shim the base. I got it from Midway for I think $30. I put it on my slug gun and it has worked so far as the scope hasn't shifted even with magnum slugs.
