AR-10 sight in.

I have a question for the AR-10 owners out there.
I am running an AR-10A4 flat top with a 16" barrel and using flip up BUIS front and rear. I used a military type m16/ M4 sight in target, and sighted in at 25 meters/yards, and all rounds are within the circle.
Since the rear sight has no elevation adjustment, as the M16/M4 has, what is going to be the POI at 100 m. ? And at 200 m. ?
I have not had a chance to take this rifle out to a larger range to see what the actual POI is going to be, I just want to know what to expect.

I don't own an AR10 but this ballistics calculator will give a good idea of what to expect: http://www.handloads.com/calc/

If your front sight has elevation adjustment I would imagine that you would use that just like a normal AR. and i thought normally the rear sight had the windage adjustment. I could be wrong though.
