may be same plane, BUT ...(16/10/2013)
May be same plane, and the .100 aperture is better than the Orig GI, but that´s about it.
The large aperture is TOO large, and even worse:
the amount of windage which comes from rotation 1/4 turn along a SCREW axis is not compensated for!
Change the apertures and you get horizontal shift!

AR15 ghost ring apeture(16/06/2017)
Two of my ARs carry this sight. It greatly reduces target acquisition time when standing offhand shooting at popup and/or moving targets.
The ghost ring presents as a blur, as it should, and does not distract from the front sight post or target. Suspect this sight was not designed for bench rest 10-ring match targets.
Did not verify windage drift upon rotation of aperture as my club rifle range is only two hundred yards and my ARs, admittedly, are not one-quarter M.O.A. firearms.
Does the sight work? It rides on my wife's AR. Nuff said?
