That site is a great resource for general AR info.

U.S. Marine Corps 25-Meter Zeroing Procedures says go one click up shoot adjust then it says" To place your actual 300-Meter zero on the Rifle, you must rotate the elevation knob on click "Down". (The range scale's 300-Meter mark should now be aligned with the mark on the receiver.)" would this mess up the zeroing aliment

The link posted is great. I do the IBZ myself.

25 meter 0 sucks. If you zero at 50 yds, you are +/- 2 1/2" from point of aim, all the way out to 220 yds or so.

IBZ is the way to go.
I have figured it out with the improved battelsight zero off the http://groups.msn.com/TheMarylandAR15ShootersSite/improvedbattlesightzero.msnw sight. Know just to make shure i have done tis right i have a detachable A2rear sight its -4 clicks right? WHich puts the 6/3 a numbers a little to left the charging handle.

I agree with above, 50 yard zero is the best. I can hit a milk jug out to 250 yards with my Bushmaster 16".

No. If you read the IBZ procedure, you see that it recalibrates the lowest setting of the wheel for a 200m zero using the long range (small peep) aperture. This allows for a 200m setting two clicks down from the 300m setting (four clicks down with a detachable carry handle). The 300m setting and all others are left to work at their indicated distances. It really is a win-win procedure that gives you settings for 200m, 300m, 400m, 500m, 600m, 700m, and 800m with an A2 fixed carry handle (only up to 600m with a detachable carry handle.
From IBZ Procedure:
"5. The lowest sight setting, however, on these sights is 300 meters so the sight needs to be modified to preserve the markings on the sight (despite the fact that no one ever sets a range on these in the real world other than a USMC range). The sight needs to be set to bottom out at 8/3 -2 clicks. This will be the new 200-meter setting."
"9. If you have to shoot targets you KNOW are 300 meters away or more, just click to the right number on the sight."
No matter where you zero at, the M16A2 sight itself(and it's civilian offspring) is calibrated for M855 62gr ball. However, the ballistics between M193 55gr. and M855 62gr. are so close that it's not going to matter much at all. The accepted tolerance of accuracy for the ammo is more than the difference (ie. the ammo itself might not shoot to better than 2-3 MOA from a rest with perfect wind conditions).

I zeroed my AR at 50 yards and it's been fine out to 100 yards & in to much shorter distances.
