That, my fellow shooters, is what you get with a standard AR carry handle. And if you zero it at 50 yards (not meters) you have a zero again at 200 meters (not yards). Now your rear drum settings of 3 through 6 correspond to the distance in meters (if you ever NEED to shoot out that far). This is the "Santos Improved Battle Zero (SIBZ) Method". Basically, you add another 2 MOA to the rear drum using a 1/16" Allen wrench (see link below for details). Zero at that setting at 50 yards . You get a trajectory from 0 to 200 meters that varies by approx. a few inches; well within minute of man (assuming approx. 3,000 fps). This is how I am setting up all my carry handle ARs (of which I have three). The link below is worth reading.
