My .02 is that the rings should be as far apart as you can on the tube. If in the last lug of the pic rail that's OK, just make sure that BOTH rings are on the base, pushed forward in the lug recess, THEN mount the scope to them. The farther apart the better. As for proper eye relief. What will be your MOST COMMON position when using this weapon? Prone? Bench? Kneeling? Standing?. As that would be the position you would determine proper eye relief with. I have the same glass. With the scope in the rings but loose enough to move: Establish your COMMON shooting position WITH YOUR EYES CLOSED, shoulder the weapon. Establish "comfortable" cheek weld, open your eye. What do you see? All black? Pinpoint hole? Now have someone else slide the scope carefully in the rings to establish a full view of the scope. Repeat the mount with your eyes closed. Then open to confirm position is "normal". Relax when doing this, and confirm it several times. Align the reticle to vertical, and torque the rings to specs (don't break a screw just had to say that :) You are done. And at 6.5 power the eye relief will be forever so not critical to alignment.
