If the notch or aperture of the rear sight is the same height above the bore centerline as the front sight your sight line will be parallel to the barrel and you will hit low at all ranges. In this case you would need enough up adjustment in the rear sight to climb out of the low zone. Try to deal with someone who knows which sights go with your particular rife.
