What scope do you have that you need a 40 MOA rail @1000 yards? There are rings with inserts that would have helped you better than a 40 MOA rail. My Burris XTR II 4-20x50 has 90 MOA of adjustment. Also have Burris XTR signature rings that have the inserts to go up to 40 MOA. Not cheap but don't have the rear of my scope high.
