thats what thought. but if you dont position you head (shoulder the rifle) in the exact same position/alignment everytime it appears your sighting line changes. at the store with an eotech mounted on a rifle, sitting on a bench rest, i moved my head around and the point of aim obviously changed. using just a single point, unlike lining up two points like open sights. you know what i mean?
im not looking for serious accuracy just something for quick easy sight acquisition. my shooting is the equivilent to pop bottles at 50 yards.
and seriously how crappy are the cheaper models?
