This sight is mounted on a 16" flattop. What is the best distance to zero it. I want something that will be close from 25 to 100yards. thanks

come on someone has to have a battle sight set up for this sight system...

I zeroed mine at 25m (yup, live in the metric hemisphere). So at 25m POI = POA, at 10m the POI is below the POA, at 50m there are no real differences POI=POA and finally at 100m POI is above POA.
I zeroed it at 25m as this is what I consider a typical CQB/MOUT/roomclearing distance.

Hope this helps a bit.

C-2-6 Out !

50 yards is optimal IMHO (see LTC Santose's article on the Improved Battlesight Zero at groups.msn.com/TheMarylandAR15ShootersSite/improvedbattlesightzero.msnw

I disagree with the 25M zero. It may work for CQB but its uselss for everything else. At 50 yards the round will be about 2.5" high and at 100 yards almost 6" high.

With the 50yard zero from 8M to 220M your round is within 2" of the POA. At 25 yards your just over an inch low - at 100 yards your just over an inch high.

Forest, the improved battle sight zero that santose talks about in that link, is for a rifle using the iron sight right? Is it the same if using a reflex type sight. I have never used a reflex/oko sight so I am in the dark. Thanks

Milhouse,
The Colonel discusses iron sights in the article (particulary A2 type and detachable carry handle types).

However the basic 50yard/200M zero works just as well for the non-elevation adjusted sights (like those on the A1 or the Back-up Iron Sights) AND for Red-Dot Type Sights providing they are mounted about 2.5"-2.6" over the bore line (just like the standard AR sights).

Mounting the red-dot on top of a flattop or using a 'gooseneck' style mount will put the sight in the proper plane.

BTW I use this zero not only on my A2 20" rifle, but my A1 type carbine AND on my Reflex (6 moa dot). It works very well in all cases.
