Kentucky Windage

The Primary Arms ACSS sight has a bullet drop compensator.

It's calibrated for 5.56x45mm NATO not the 6.8x43mm SPC I'm using it with.

Out come the ballistics calculators...

Out to 400 yards they're really close enough, nearly identical.

The 500, 600, 700 and 800 marks work out to 475, 550, 650 and 750 close enough for government work.

Not that expect to ever shoot past 200 yards.
