However, the referenced article notes that some people advocate:

"... zeroing the rifles and carbines using the large (0-200) apertures with the rear elevation set at 8/3 or 6/3. This zero provides a very flat trajectory with a maximum ordinate of just over 1.0” between 50 and 200 yards. Thus, when aiming center mass with a 12” standard at 300 yards one could expect that most rounds will impact within 4 to 5 inches from point of aim out to 250 yards.

Thanks for the link.

I can't put A2 sights on my rifle. The A2 sight is the 8/3 sight. To get that much adjustment the sight has courser threads and the elevation screw go's down into the receiver. I have the A4, 6/3 carry handle. The elevation screw is shorter and it doesn't go into the receiver like the 8/3 does.
