That’s how I like it as well. POI is about 2” lower th and POA at 25.
At 100yds it’s just about dead on. ETA: I do this for practical reasons. Shooting plates from 25-100 yds it makes it easy. |

I always zero my non-magnified ARs at 25 yard using m193.
M855 comes in a bit lower POI.. |

25yd zero will hit about 10” high @ 150-200yd/m
Two inches low at 25yd is roughly 50/200m zero, about 2” high @100-150yd/m... a 6” max point blank range out to about 225(ish) yd/m. |

Quoted:
Watching a show with Larry Vickers. He just said you never want your point of aim to be your point of impact, while shooting a M4 at 25 yards. He said at 25 yards your poi should be approx 2 inches lower than your poa. Never heard this or practiced this. But im no d-boy. I also dont shoot long distance. An M4 should be zeroed so that a chest/neck hold will put it in him from 0-300 yards. After 300 start taking a hold or call for fire/CAS. Here's ranging for M193 using a 43 yard zero.

It depends. It depends on your rifle, your sight height, your ammo... everything.
But just for an example: A2 iron sights are 2.6" above the bore. Using a 100 yard zero, your POI at 25 yards should be 1.5" lower than your aim. The bullet will rise to zero at 100 yards, level out, and then should drop to be 2.5" low at 200 yards which means no elevation changes are necessary shooting at a level target within 200 yards. The same zero shoots a foot low at 300 yards. This is using a rifle length barrel with M193 ammo. |

I prefer the 36 yard zero with red dots and eotech. The spread out to 300 yards is 5.5 inches when zeroed at 36y. The 25 and 50 yard zeros have ~10" of spread out to 300.

Before ARFCOM became a low rent haven for trolls, we used to have real firearms subject matter experts hang out here. Google "LTC Chuck Santose Improved Battlesight Zero for M4" He posted it here many moons ago before he decided the juice wasn't worth the squeeze. It may even be archived, but the old link I had apparently is screwed. It's hosted elsewhere, to include Scribd. It was a very helpful read, especially for someone like me who learned how to zero on the "Thousand Inch Range".

Quote HistoryQuoted: M4 zero POA/POI ideally is at 43 yards but call it 50. The bottom line is that zeroing a weapon should be confirmed at range. For an M4 I use 200 yards and with a 50 yard zero it should be about 3-4" low but most folks can't shoot well enough to establish that. So use an IDPA target and take a neck line hold. If you're in the chest call it good. ALWAYS confirm zero at range given the luxury of time. An M4 should be zeroed so that a chest/neck hold will put it in him from 0-300 yards. After 300 start taking a hold or call for fire/CAS. Here's ranging for M193 using a 43 yard zero. https://www.AR15.Com/media/mediaFiles/696/M855_png-1245322.JPG Changing the sight height will significantly change that table. |

I prefer to zero 1" high at 50, which puts me 5" high at 200 and dead on at 300.
This is actually the best way to zero a gun with a carry handle by the way, since the elevation drum starts at 3. |

I just put a few of my ARs on 36 yard zero earlier today. Now that they are on target the next trip will be seeing their impacts and recording them at different ranges using a common ammo.
(2) 16 inch in 5.56 (55 gr IMI FMJ) (1) 5 inch in 5.56 (77 gr IMI Razorcore) (1) 7 inch in 5.56 (55 gr IMI FMJ) (1) 12.5 inch in .308 (M118LR) If I don't like it I will go to 50 yards and do the same. I will do muzzle velocity checks too and use Strelok Pro to help record and verify. I plan on recording 25, 36, 50, 100, 200, & 300 yard impacts. |

Too many variables....
I use a 2.7" sight height...as that is right between lower 1/3rd and Absolute co-witness for my red dots. Zero would depend on the caliber, barrel length, optic, and ammo. |

Quote HistoryQuoted: Lol, I'm sorry but a bullet doesnt rise to zero. A bullet starts dropping as soon as it leaves the barrel While the bullet itself does not rise (not higher than the angle of the barrel), the barrel is pointed upward and the bullet will eventually cross the plane of the sight (zero) before it falls. Depending on zero, it could cross the plane twice. |
