Surely a rethread: zero distance for ar

I searched and didn't see anything posted. Kinda hard to believe.
What are you baws' preferences? I just sighted mine at 50 yards but am thinking of going to 36. It shouldn't make much difference between point of aim and impact at close range as between a 50 and 36 yard zero, but--a difference nonetheless.
And all of youtube suggests 36 gives the closest placement overall at 25, 50, 100, 200, and 300 yard outings. My purposes are going to be about 50 yards and under or about 300 yard shots.

Good article from the Armory Life: Is your Carbine's Zero Wrong?
Author' take: he prefers the 50yd zero

This video is an excellent guide on AR zeros. I use a 2.27” Unity riser on my gun, so a 57 yard zero gives me the tightest group out to 300. 57 yards is a bit oddball, but zero at 57 is 1.8” low at 25. So I sighted my rifle in about 1 3/4” low at 25.
If I were to shoot my gun at point blank, 100, 200 and 300 yards, while keeping the crosshair (or red dot) aimed at the exact same spot on the target, all four of those shots would be within about 6” of each other vertically.
In other words, I can hold center chest on a human sized target, and I’ll hit +/- 3” vertically from point blank to 300 yards, without memorizing any holds. I’ll take that.

I always had to shoot a tad high with a red dot at 300m but your method is more intuitive to the purpose if those are your results. I like it.

I watched a YouTube that said the soldiers in Afghanistan would zero at 36yrds for patrol and zero at 100 for qualifying. If you can hit a torso at 0-300 you going to be all right. I zero'd mine at 30ish or so. Whatever the second row of concrete is at sherbourne pistol range. The berm is closer to 60 than 75yrds fwiw.

5.56 at 100, .300 blk out .75, .308 at 150. But I hog hunt with all and deer hunt with the .308 occasionally. Scope on the ar10, and red dots and magnifiers that I switch out with a thermal that holds zero on the ar15's (mainly just on the .300 blk since its the better hog gun imo). All personal preference.

My 5.56 is zero'd at 50/200. My optic has BDC based on that zero with holds out to 600. To be honest I've only shot it out to 200, but its pretty spot on both at 50 and 200, so trust I could hit torso target out to 400+ with confidence.
Waiting for my suppressor to determine holds on my .300 blk with subsonic ammo. Right now it's zero's at 35 yds with 150grain supers. That gets me a good 3"-4"" impact window from close up out to 100 yds, which as a home defense gun, it's in the ballpark of what I'm looking for.

I went to shoot mine this weekend, it was good. After I tweaked it, 10 shots all within the center 3-4 inch box at 50, and as expected a little high at 100 but just a few inches. Good enough with my fixed 3x. This range has a separate 200 lane, so I didn't go out that far but I know it will hit from a previous time.
ETA: actually all in a 2 inch grouping as I look back at the paper.
