I haven't been around in a little while due to work but I've come into some problems and figured I'd check out what input you guys have. We're all working with the EOTech 552 and noticed some things that we are not sure are correct. After spending some time zeroing from 25m I finally managed to get a good zero with my shot group being with 3/4". I then went back to the 50m line and shot again and found that my shot group was 6-8" above the point of aim. I found this to be quite a drastic change and was wondering if this is normal. Confirmed all of this with 3 different shooters and all of their shot groups were much higher at 50m, however some were only 3" higher while others were as high as mine. I'm not very well versed on the EOTech at all so any input is always appreciated.
