And as far as the question "SHOULD I CHANGE MY RINGS?", the answer is three parts. (1) If changing them will cause clearance problems (see answer above) or if the change will be to something not as strong/sturdy/reliable, then the answer is "NO, you should not change them." The second part is that, commonly, the lower the scope is, the closer it is to the center of the bore and that is a GOOD THING. Thirdly, eye positioning is important to accuracy. If lowering your scope will give you a better cheek weld, resulting in better, more consistent centering of the eye behind the scope, then DO IT. If you get a better, more consistent centering of the eye with the higher rings (maybe due to face shape or stock configuration) the DON'T do it.
