I had previously been using both the 25 and 50 yard zero. Was never really happy with either of them. Then I came across the below YT video from Shawn Ryan who talked about the 36 yard zero. Great thing about this zero is that all the way out to 300 yards, you only have a 5.5" spread. 25 yard zero has a spread of 10" and 50 yard zero has a spread of 9.5".

By far my favorite zero for 5.56. |

Of those shown I prefer the 100. 75 might be better.
Don't much care about > 200 on an AR with red dot. |

25m has been proven over and over again to be the correct 0-300m zero
Why try to reinvent the wheel unless you are precision shooting? Edit to add for those slow on the pick up as I typed that too quickly. Target placed at 25m, zero sights at 300m |

I use a 20" AR with a carry handle and M855 ammo. The only way for my range marks to work properly is zeroing using the "z" mark at 25m. this is a 25m/300m zero. A 36 yard zero would completely throw everything off for me.
I also shoot on a farm and we usually shoot steel plate targets from 100 to 400 meters, so for me, sticking at 25m zero makes more sense. I guess it depends on what you are using the rifle for and what kind of sights you are using. |

At the ranges where you're significantly more likely to use a rifle with a red dot, the 50y zero offers less deviation. |

I use the 50/200 zero
But then, I zero all of my centerfire rifles @ 200 regardless of caliber (.204, 5.56, 308, 30-06, 300 wm) Less to remember / think about that way |

Zero for the distance you intend to shoot and know your holds.
People make this way more complex than it needs to be. Real world use...Zero at 100M for 5.56 at any normal velocity and call it good. From 0-250M you don't even have to think about it...and that is 99% of what you might do with an AR. Plus, with a red dot...you aren't getting an uber technical zero anyway. |

Sure that works for your BUIS, or carry handles.
Using optics? I use a 100yd zero and know that I always have to hold OVER at any distance and it also works with BDC reticles. |

Zero at 36yd and see if it's actually a zero at 300yd. My experience has been NO.
Real 300yd zero for 10.5" guns is closer to 25yd ironically. You have to chrono and CONFIRM, otherwise it's probably not really a 300yd zero. |

The only reason for preferring a 25 or 100 yard Zero over any other is that we like nice, round numbers. If the 'standard' for a yard was a slight percentage longer that what it has traditionally been (so that 25*36" was the same distance as what 35*36" is) no one would suddenly be screaming that a 17-yard Zero was the be all and end all of what distance to Zero at.
The advantage of the 35-yard Zero is that the bullet neither rises above, nor drops below, a usable amount out to a distance longer than commonly found in combat. I use 35-yards but the change in PoA/Poi is minimal. It doesn't matter if you measure the distance in inches, yards, meters, Russian arshins or just call it "blue"' it's just a distance. |

Assuming a 10" vitals zone, a 250yd zero for a 12.5" 6.5G will have about a 300yd MPBR. With my Vortex 1-6 dialed to 6x, that corresponds to 2mils~350, 4mils~500, and 6 mils~650y.

I use two zeros: 100 and 200. The 100 is on a light carbine, the 200 is on a medium-range oriented rifle.
Most of the time when I shoot with the medium-range rifle, I have time to check holdovers and account for them precisely. When I don't have that time, putting the crosshairs on the target covers a lot of ranges with a 200 yard zero. With 100, all corrections are up. It's easy to roughly account for lots of different ranges quickly and without thinking just by aiming a bit high. For the shooting I do with this rifle, that's good enough. |

50y zero for a red dot. Confirm windage at 100.
 Attached FileBad guy is between point blank and 300 yards away, put dot center of mass and hit center of mass. Personally probably not going to be shooting at someone beyond 300y with a red dot. Not a fan of the 36y zero having the 100-200 yard impacts so much higher above point of aim than 50y zero. |
