Messing with it at the LGS, shooting at 25 yards indoors, there is some distortion that I could notice when shooting both eyes open; my friend who owned the rifle and MRO noticed the same thing. I also noticed it on a different unit, while just coonfingering it at the store. I use correctional lenses, but I don't have this problem with the Aimpoints (although the Aimpoint T1's dot looks like a comma, as opposed the MRO's perfect dot).Heard on somewhere else that there might be a fish eye effect when transitioning targets. Can anyone chime in? Possibly because of the different sizes of entrance and exit glass?
