>at the ranges you are likely to legally shoot someone with an AR the offset between the barrel and your sights has a significantly greater effect on where you hit than the zero you chose to the point where none of the popular zeros make enough of a difference to make a difference

How much worse was the 25/300 M zero compared to the 50/200 yard zero? Were there any significant problems or reports between the adoption of the A2 in 1983 and the mass adoption of the CCO and RCO?
the acog/rco is a 50/200 meter zero by the way
>no it's 100 meters
if you are just using the chevron like a red dot like you are supposed to within 250 meters the deviation between 50, 100 and 200 meters is only the thickness of the chevron, so pretty much negligible
