OK...so I should know, but I forgot and today it came up in a class I was attending...No one else seemed to be able to remember either, so I turn the question over to my able colleagues at the firing line.

When battle sighting an M-16 at 25 yards (the 1,000 inch range), how far does each click move the bullet impact on the rear A1 sight?

How about the A1 front sight (ie with 5 detents)?

And the A2 front sight (with 4 detents)?

And last but not least, the A2 rear sight windage (Standard not NM)?

Any info would be greatly appreciated as a few beers are on the line here....
