cant follow the link, but there is a chart that shows all the differences in the various versions of the leupold scopes. Very detailed info.

Hard to take that article too seriously, given the spelling, grammar and syntax errors... it was a painful read.
I tried to follow the links at end of article, but they appear defunct. Anyone know how or where the Rifleman series of scopes fit in here?? Would be kind of interesting if today's rifleman was equivalent of 1970's Vari-X?
