 proper sight picture when using AR-15 open sights ?

I have a Stag AR-15 on which I am using the AR-15 open/iron (carry handle) sights.

When using open sight like this, what is the proper sight picture ?

Should the very tip (in my case I have a green optic insert on the front sight post) of the front sight post be aligned with the target with the tip of the sight post being held JUST OVER/ABOVE the lower/six o'clock position/bottom of the back iron sight ring OR should the tip of the front sight post be CENTERED in the back iron sight ring while being aligned with point of impact/target ?

One reason I am asking this is because when I am shooting at just 25 yard target my shots are approx. 8 to 10 inches above/higher than my intended point of aim. The windage is spot on, no problem there.

I have the rear carry handle sight adjusted all the way down as far as it will go and yet the shots are still this 8 to 10 inches high.

Does this mean that I just need to go WAY UP with the front sight post adjustment to bring my shots down to point of aim ?

Thanks.

Tip of front sight in the middle of the rear circle sight. Typically you sight in your irons at 100 yards, 25 is kind of close.

You will need to raise your front sight to lower your point of impact. When you are using the front sight, going up(raising the front sight) lowers your point of impact, and vice versa. On the rear sight and red dot sights, if you are shooting low, you lower your sight.

Hope that helps..

Thanks for the reply Covert.

If my sight picture is in center/middle of circle (instead of just above lower rim of rear sight circle) that is going to make my point of impact/grouping even higher !!!

Perhaps this has to do with the sighting in range, i.e. just 25 yards. But I am doing that because I figure that would be the max. distance I might expect to really hit anything accurately with open sights, especially if shooting off-hand.

I am going to try raising the height of the front site post some, see what that will do.

If I want to do accurate shooting for a greater distance than 25 yards, then I have another AR on which I have a scope mounted or I would possibly put a scope on this Stag instead of using the iron sights.

Thanks again.

If I were you, I would buy a red dot optic like an Aimpoint, Eotech, etc and sight that in for 25 yards. Then keep your irons sighted in at 100 yards. That would be best for the distance you intend to shoot at.

Depends on who ya ask, or what school of thought u follow....plenty of people choose the 50yd BZO, which is good for shooting up close and out to 250+ yds. I like the 50yd BZO as yer drop at 25yds is about 1.2" low and out to 250yds yer about 1.6" low at about 150yds the bullet hits its max apex and is only about 1.5" high. A 100 yds BZO will give ya 1.8" low at 25yds and almost 5" low at 250yds. So it really depends on what distance u plan to shoot...the 50yd BZO is a bit more universal for more distances.

You want the tip of your post in the center of the ring no matter what. It sounds like all you need to do is raise your front sight post a bit to bring your groups down.

With practice you can be very effective with irons to distances MUCH MUCH farther than 25 yards.

I'd zero them both a 50 yards. By zeroing your irons and RDS at different ranges, you lose benefits of a co-witness.
