Trying to see if a detachable rear sight from an M&P 22 will work on my flat top AR in 5.56... Would accuracy still hold true at sub 200yd distances? I know about the arc path and all that, but would attaching this sight just be a waste of time?

Is the M&P22 a mil-spec design? If so, it should be fine. Just sight it at 25 yards and you'll be right on at 300 yards and a little high at 100 and 200 yards.

I know for a fact that the M&P sport 556/223 uses the same sites as the 15-22.

You will have no issues, just do as cjive recommended.
