At What range did you zero your AR?

You should be able to adjust to 1/2" @ 100 yards. You can get 1/4 MOA rear sights for 1/4" @ 100 yards.
You can adjust the rear sight for your "come up" settings for different ranges, so you don't have to answer questions like At What range did you zero your AR?

If, for example, you shoot at 100m, then a 100m zero would be good.
You haven't mentioned your sight height, which makes a difference. If the sight is 4" up a 50m is also a 150m zero. If the sight is 2.5" up a 50m is also a 200m zero. Depending on ammo and so on.

height to the base of the sight or the cross hairs?

I am ready to throw the AR15 issue sights in the garbage. Everything I shoot hits high, the adjustments are too coarse to dial right in and as far as I am concerned, they turn a superb gun into a mediocre one. (I like to sling up, go prone and shoot out at the longer ranges).

I see some NM sights in the near future and if they don't work, the AR will get the bloody punt and I will get a pimped out Norc M14.

If everything is shooting high, you need to adjust your front sight.
Set your rear sight for the desired zero, the adjust the front sight until elevation is correct.
 
3X ACOG....100m...measured out additional yards past 100y to equal 100m then zeroed.

Iron sights and Aimpoint M4. 50 yards...according to many articles this will cause the gun to shoot high at 100y and then be POI/POA at 200y.
 
My FastFire II that piggies back the ACOG @ 25 meter's. My ACOG 4x @ 100 meter's and with the BDC it's a brezze out to 600 meter's. If it's a good shooting day.
;)
 
All of my AR's are Zeroed at 200m with a 6 oclock hold on a 22" tall target. That way the same sight picture can be used at 300m with no adjustments. For 100m, the rear sight must be raised 2 clicks.

I DON'T UNDERSTAND ANY OF THIS???? can someone break it down...I have a swiss arms classic green with a aimpoint comp3 zeroed at 100 yards...should I change this...what would be better

This is for my 14.5" Guns ...YMMV. I use a 50m zero for most training and courses. This gives me POA=POI @ 50m. But more importantly the POI is within 2 3/4" to 3" from my hold to impact out to 225m. It essentially gives me a flat range from about 7m to 225. Not precise but good for my needs. Indoors on SIMS packages I just point shoot. For Service rifle I have exact zeroes from 100m to 500m. I use a magnified optic for SR and an Aimpoint or a KAC 300M BIS for everything else.
 
I would think that everyones would be different depending on what the rifle is going to be used for.
What distance will you need the site to be bang on for ???

Zeroing AR/ C7 rifles....

For me:

Iron sights should be point of aim point of impact at 50 meters. As long as an optic is also 1x power (or holograph sight for that matter), I'd zero it the same way as an iron sight and do it at 50 meters.

The C79 (3.4X power) is point of aim point of impact at 100 meters, I'd argue that any equivalently mounted and magnified optic should be similarly zeroed.
