Thinking of picking up a used one for a 13" Scar 17. I recall reading somewhere that the eyebox can be finicky from side to side and you having to keep your head centered at all times to use it properly. Any truth to that?
How's the eye relief on it?
Eye relief is very good, don't remember exact number but around 3.7" I believe. Its not exactly "forgiving" if you move your head around but its not the worst either. At 1.1x its no issue, only when you start increasing the magnification do you really notice it if your not lined up.
