Can anyone measure the width of a 4 Bolt Ultralight NF Ring?

AnTi-X has minimal mounting width on the rear rail, the NF 4-Bolt ultralights look like they might be svelte enough to fit without hanging off the rear or front like this (which aesthetically displeases me):

Hoping someone can put a caliper on a ring to get a width and thus a reasonable indication of success before I send it on a set.
