S&W M&P 15 Iron Sight Adjustment Question
Does anybody happen to know how much each click on the elevation and windage adjustments moves the POI at 100 yards?
This carbine has the 16 inch barrel and the carry handle with the rear sight. Also does changing from the large apature to the small apature on the sight chaange POI?
Thanks,
FE Duncan

A standard A2 style rear sight is 1 MOA per click, the larger aperture is the same as the small in that part. The larger aperture is mainly for faster target acquisition.

Going from memory, so bear with me. At 100 yards, each click for windage will move the POI a little more than half an inch. For elevation, each click will be around 1.5" (using front sight, not the elevation drum on the rear).
And yes, there will be a different POI between aperture with the A2 sight. I don't remember how much difference, not enough to matter on man sized target shooting at COM. A couple of inches.
