AR-10 Iron Sights
Hello Everyone,
I’m brand new here. I hope I’m posting this in the right place. If not please let me know. I am considering re-zeroing my iron sights with the rear sight elevation up a full rotation from bottom. The reason I’m considering doing this is that at 25M zero my poi is 8-10” high at 100yds and I can’t dial the rear sight lower because it’s bottomed out at the start of zeroing. If I rotate the rear dial up one full rotation it will let me dial for expected range between 80 and 200 where the rise is at its worst. The only pitfall I can see is it will prevent me from longer than 600 meters, which I never expect to shoot. I’m interested in whether anyone else has tried this yet. Thanks! |

What happens if you zero at 100 yds? You will be low at 25, but 2” likes w at 25yds is still fine for 90% of use cases.
Is there an optic in this system? |

I can't speak to the AR 10 directly, never had one, but I can say what was done zeroing the M16A1 at 25m.
The "battle sight zero" targets had an aiming point in the center that you sighted on, and an "x" a couple inches below that, where the bullets were supposed to hit. With the ammo we used (issue M193 ball) sighting that way put you a couple inches low at close range, a couple inches high at 100m and dead on at 250 meters. If you're a math minded fellow, you can find the info and calculate the actual amount of offset between aiming point and bullet impact at different ranges, and come up with a number that will allow you to sight in at 25 and be dead on at 100. For me, its simpler just to sight in at 100 yards to begin with. I will shoot a few rounds at close distance, just to verify the bullet is going to be on the paper at 100, then move out to full distance for precise sighting in.
