Sorry if this has been done; which seems to be the better zero procedure for ar battlesite (16" chrome lined carbine)? Standard 25 yd or Col. Santos' 50 yd IBSZ? Thanks.

IBZ means [b]Improved[/b] battle zero[;)] so the IBZ is the way to go.. also, the standard zero is 25 meters not yards (me thinks)

Ditto that. First, it's easier to find a 50 yard range than a 25 meter range. Second, the IBZ gives you a flatter trajectory out to 200 yards.

Ditto, 50 yard [b]IBZ[/b] and actually the flatter trajectory extends to 300 yards. (dead on at 200) Mike

I have an M4 with an Arms #80 flip up sight. Would I still be better off zeroing at 50 yards? My rear flip up sight has no elevation adjustment.

If you can't adjust the elevation then the IBZ is an even better idea. The whole concept behind the IBZ is that by zeroing at 50 yards the bullet will be within a couple inches either above or below the point of aim for pretty much every distance that you're liklely to take a shot in anger with an AR.

Here is a good discussion of the various zeros. http://groups.msn.com/TheMarylandAR15ShootersSite/zeroingmethods.msnw If I am not mistaken, using the 50 yard zero will keep the bullet within +/- 4" out to about 275 yards and down something like 5"-6" at 300 yards.

You're mistaken [;)] Its +/- 2" from 8m to 220m (about 240 y). The USMC 36y/300M zero is closer to a +/-4" zero.

Another vote for IBZ. Ray

I'll also chime in for IBZ, for all the reasons stated above...
Link Posted: 10/6/2003 11:47:10 AM EDT
Do you follow the same procedure for IBZ as you do for the 25 meter zero?
Link Posted: 10/6/2003 1:52:15 PM EDT
I'll bite. How do you do IBZ?
Link Posted: 10/6/2003 2:42:58 PM EDT
I want to know how to do the IBZ too. The MD site just isn't clear enough, for me anyway. Can you go out to 800 yards with it?
Link Posted: 10/6/2003 4:39:19 PM EDT
Is there a huge difference between meters and yards in the distances we are talking about? I usually just pace it out anyway. Is an ARMS #80 twice as good as an ARMS #40?

btt.

if you use the IBZ on a regular sight w/the elevation wheel, then your numbered markings still work normally; i.e. 4 equals 400 meters, 8 equals 800 meters.. so yes, you can go out to 800 meters.. but, if you have a non-elevation adj. sight, then have fun holding over [:D] edited fer spelling

Thanks for the replies. I did the sight mod and zero per Lt. Col. Santose's directions, (my bushy carbine only needed one extra click down). This is a very accurate weapon. Now if I could ingrain a good consistent stock weld.

I just got to chime in on this.....I zeroed my AR using the Army's A2 zero target at 25 yards (close enough), with the rear site up one click.....then I put the rear sight back to the 3/8 index, and took it out to the 100 yard lane, it was hitting excatly at the POA. so why is everybody so keen on using this "IBZ" when there is nothing wrong with the Army's zero method.
