Gives an instant check to make sure the gun is perfectly level for
every shot, so every shot goes where it's aimed. If you sighted in
carefully at 100 yards with the crosshairs level, then canted the
gun just six degrees you'd move the next shot over 1/2". Not
much, but enough to completely miss a small target, or wound a
larger one. The problem gets worse at longer ranges. Clamp the
ACD on the scope tube where it's visible to the non-sighting eye.
