I've been doing research one which Zero would be best overall for a M4; so far I have gotten alot of people are saying to go with a 50 yard Zero vs the U.S Army's Standard 25 yard zero.
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.
