Hey no worries guys. If somebody doesn't have the answer off the top of their head then I go into phase two of my research and start hitting the phones/emails. I have a problem with over-researching things, and it saves me a lot of time if somebody else has already been through it! But I'm willing if need be. Anyway...

Using Chris's method, I find that a "B" measurement of .390'' (9.906mm) on the Burris Signature High rings is a REAL tight fit, not even sure if it will clearance the lens covers.

Here is the math. If you guys are really bored or interested, one of the two. Or if you see a mistake please point it out!

.390'' = 9.906mm My Nikon Monarch has on O.D. at the objective of 57.3mm (So I'm trying to clear a distance of 28.65mm to the center of the rings as I understand it).

9.906mm

+12.70mm (gets us to the "A" measurement or centerline of the rings)

= 22.606mm

+ 6.35mm (estimating 1/4 inch on the bases for dovetail bases could be a little more or less)

= 28.956mm = total height/clearance

So 28.956mm minus the required 28.65mm equals only 0.306mm of wiggle room!!!

Don't know if the Burris Signatures come a size higher or not. Could go with the Burris extreme tacticals, those are taller. Or maybe I should look beyond burris? Thoughts?
