MidwayUSA: Ring Height
here is a chart that MidwayUSA has that is a guideline for ring heights. Doesnt go down to 44mm for 30mm tube is the prob though. I am thinking you are gonna wanna go with medium height rings
From reading previous posts, it sounds like the Burris Signature rings are the way to go. I am planning on buying the exact same scope you just bought, and then using the Burris rings.
