I doubt you would even need a 20MOA rail on that rifle. That scope has 110MOA of ele adjustment in it. If it were me I'd run Talley LW's and try and keep as weight off that rifle as I could. Personally, I couldn't imagine throwing a 30oz scope on a 7# rifle. The balance point would be so far to the rear of the rilfe that I wouldn't run it. I've NF's scopes here on some rifles but not on a light(er) rifle. Balance is something that is often overlooked on a rifle when putting it together, but it sure is something that you'll notice when you're done. Not trying to talk you out of that scope, as I have them too and they are nice, but just trying to get you to think a little more about the project as a whole. Good luck, Brad.
