    Would someone please explain to me in detail how to do a 50yd zero with iron sights.



    Thanks Guys
    You do not think the 9mm is effective? Then let me shoot at you.

    here you go. This is how all my .223 rifles are zeroed.

    Is this hard to understand? Then why does it get unintelligible to some people when 5 little words are changed?

    Put a target at 50 yards - fire 3 shots aiming center mass. Adjust your sights until you hit where you aim. Now your gun is zeroed at 50 yards, and will be dead on at the other end of the spectrum - which will depend on what caliber gun you're shooting, what the bullet weight and ballistic coefficient is, and what the muzzle velocity is. How you make the adjustments to your sights will depend on what type of rifle you are shooting.

    Any idea on how many rounds it will take?

    ideally, one 3-shot group to zero, one 3-shot group to check at 100yrds. Realistically, you'll probaly need a few more for adjustment.

    It should take at least 10 rounds. Shoot 3 - adjust sights - shoot 3 - adjust sights again - shoot 4 to confirm zero is good. If you need to keep adjusting then you need to keep shooting.

    If you are shooting an AR-15 you will want to be making your elevation adjustments at the front sight post. Turning the front sight post in the direction of the arrow will raise the impact on the target. With a 20" barrel one click (1/4 turn) will raise your impact 1.25 inches at 100 yards (.625 @ 50 yds) - if your barrel is shorter this change will be slightly more because of a shorter sight radius. If your rear sight is adjustable for elevation you should have it set on 8/3 the whole time you are zeroing your rifle - all elevation adjustments for zeroing are made at the front sight.

    to make the adjustment of the sights from POA to POI, you better have the gun held solidly in place during the sighting and adjustment.

    And, I agree 100% with the 3 shot method of moving the sights from POA to POI. It works extremely well with optics as well.

    If you have bore sighted your rifle you can start at 25 yds. Adjust sights so rounds are hitting about .5" low center of bullseye. Move target to 50 yds, shoot 3 rounds, adjust as necessary.

    If you don't have a bore sighter, start at 10 yds, move to 25, then 50.

    Depending on your shooting ability, if you have a steady hold and the first shot is way off at 10 or 25, no sense in wasting bullets in the same area - adjust accordingly.

    See many folks marching targets out to 50/100 yds, firing, wait for cease fire, move target in a bit, fire, repeat. It's usually best to just start out close.
