Using the formula found here, http://www.opticstalk.com/how-to-det...topic5946.html, it looks like all I will have to do is select a base that fits and subtract the base height from 1.3" (60mm true obj bell / 2 and add 3mm for lens the cap converted to inches and slightly rounded up)to find the ideal ring height (assuming a 3mm thickness for the Butler Creek lens caps. I'd like to stay with an all steel base like Seekins, Badger or a similar company.
