I found the following data: (from AR15armory.org)

" If You want to shoot 15-100y for most of your shooting. With your current zero you will be ~6" high at 100y depending on barrel length and ammo. Since 25y is your zero, everything beyond that will be high, ~2.2" high at 50y, 6" at 100y, ~8" high at 150y and ~9" high at 200y. Your numbers will be worse than a Mil zero (numbers given by TS above) because that zero target you used is really a 31y zero because it requires adding elevation to zero (the z setting on the elevation knob on the carry handle iron sights, 8/3 or 6/3+ 1) and then backing down to 8/3 or 6/3 for your battlesight zero.

If you use a 50y zero, then you will be ~1.2" low at 25y, dead on at 50y, ~1.5" high at 100y, ~.5" high at 200y. See these charts for a very good description and recommendations from the Army Marksmanship Unit. AMU zeroing data "

I'm Using a Eotech 511, on a yankee hill raiser; iron sights are alerady zero'd. Just trying to figure out how to get setup here.

Does anybody know if they make 50 Yard laser boresight Target Like the Eotech one ? I know some People in the Army/Military have a AKO account with different documents or files for Targets i heard.
300 meter zero is the standard Army Zero. The 25 yard zero is used to approximate a 300M zero, for time saving purposes. Same as for the 50M or yard zero is used for a 200 (225) yard zero. It's damn close, but you should always zero at the furthest distance as a final check.
