While zeroing, elevation is set at -2 or -4. After zero is obtained, is elevation returned to 8/3 or 6/3, or is it supposed to be left at -2 or -4?

If you're shooting with the small aperture at any distance between 50 and 250 yards, leave it at -2.
If you're shooting at 300 with the small aperture then set it back to 8/3
If you're shooting at longer range with the small aperture then set it to the number on the wheel.
The large and small apertures are not at the same height. The large aperture at 8/3 is the same as small aperture as -2.

Okay, I zeroed at 50 yards at -4. I set up a B34 target at 229 yards, and I'm hitting the bottom edge of the target. This is with a Bushmaster 16" HBAR firing XM193, AE 223, WWB and either Q3131 or Q3131A, I don't remember which.

From the instructions:

[Editor's Note - there is some variance with the offset of the A2 aperture - they SHOULD be a 2 click difference - however some manucatures produce them with larger offsets. Setting the sight to 3 then flipping to 0-2 might now work for your AR. Check it at the range, you want the group to be centered at 50y, you might need to set the sight at 3 +2 or even 4 to get the large aperture to be correct]

This is battlesight, not X-ring shooting!

I'm using the small aperture, and I don't understand what they mean about the "offset of the A2 aperture."

Bottom of target means out of action, I guess. That would be below the vest, right?

Quoted:
"offset of the A2 aperture."

That's what I was referring to in my first post when I said "The large and small apertures are not at the same height. The large aperture at 8/3 is the same as small aperture as -2."
