Our Ribs can be made in different heights and pitch to help change your Point of Impact, higher ribs help to get your head into a more upright position to help eliminate the accidental head lift, and for customers with no more downward adjustment left in their combs  a taller rib gives you back your adjustability. If you're wanting to change your Point of Impact will need to know what your guns point of impact is now, so that we can make the necessary adjustments to the new rib. If your wanting to order a taller rib and don't want to change point of impact, you will need to also raise your adjustable comb approximately the same height as the back of your new rib Customers that order a taller rib and don't have an adjustable comb and want to keep the same poi, please keep in mind that you will need to raise your (head - eye) approximately the same height as the new rib. We do carry pads in different heights to help get your head up, they can be found on our accessories page
