Q? about A2 and A3 sights

[RomanKnight]

The AR A2 sight is calibrated to 800m, with half MOA windage adjustment, and 1 MOA for elevation. The sight on A3 handles has half MOA adjustments. What can I change on a A2 sight, to have 1/2 MOA increments, but maintain 800m calibration?
Thanks

This may help.


ETA: I don't remember it having pop ups before but it does now.

I thought the carry handle rear sight only went out to 600M?

It does, or at least that's all it's marked to.

However, I believe NM sights are calibrated to 1/2 MOA adjustment. Maybe what you are looking for is a NM elevation drum.

Thanks. Looks like NM answers the question.
