Two points that may have influenced individually or combined to affect my opinion. First factor, I am nearer 60 than 50 so my eyesight is not as sharp as my younger days serving in the Marine Corps. But then that's why I wanted illuminated optics.
Secondly, the Eotech XPS2 I used is mounted on an Israeli Tavor which is a "Bullpup" style carbine that is chambered in 5.56/.223.
The purpose of this red dot Holo site was for quick target acquisition. The red dot which is actually a red dot surrounded by a red illuminated halo seemed difficult to locate and seemed to be at the very upper portion of the view lens. Perhaps this is due to the eye relief on the Tavor. I found the red halo or ring around the dot distracting and it obliterated my view to some degree of the target field.
The next issue is the need for a screw driver etc to adjust windage and elevation. I see no reason why an easy to reach knob for adjustment couldn't be used. Also the windage adjusting screw did not turn in clear clicks for more accurate adjustment of MOA. The elevation screw did seem to move in discernible clicks and was easier to adjust. The provided instruction card was useful.
It certainly functioned adequately but in my opinion needs some tweaks to be what I consider ideal.
I have a 15 year or perhaps older Pro-Point on my poor man's version of "Cooper's (Steyr)scout rifle and it truly does provide instant target acquisition which should be the point or purpose of an illuminated red dot Holo ...
