Anyone have quantitative data like group mean radius?

A true "reducer" on the objective lens side is best for shortening the focal distance for dry firing. Otherwise reducing the eye box is stupid.
An aperture lens on the ocular side makes more sense.

Maybe growing up with an A2 beat sight alignment into me, but despite a 1.57" mount, I've not noticed a parallax issue the few times I've been to 600yds. I mostly got a smoke tinted aperture lens so I wouldn't fry my eye on a west facing range.

With a 3" eye relief, the 1/8" hole and 5/16" chamfer is big enough to clear my 20 MOA BDC with at least 10 MOA margin.
