Sorry guys if this has been previously asked, but I have an A2 front sight (standard post) on a 16" AR and an A2 MI flip up railed sight on a 20" AR. As soon as the snow melts, I'll be adjusting the irons on the two AR. I have Buis'es at the back (only windage adjustable), so I'll have to adjust the elevation at the front sights only.
I'm wondering for each of the two setup, how much vertical MOA one click (1/4 turn) is equivalent to?
