Got an EOTech for my AR yesterday and took it out to the range today for zeroing in. Right out of the box it was almost dead on at 25 yards. I made some slight adjustments and it shot about a 1.5 inch group at 25 yards. But at 100 yards it was about 6 inches north of the target. Made some slight adjustments again and she was shooting pretty well. At about 100 yards I was shooting about a 6-7 inch grouping with 30 rounds. Which isn't too bad since its a 1x scope and I'm not an extremely experienced marksman. Here's some porn..
