This cheek pad was designed with the black powder long range shooters to incorporate all the needed features they need. The universal fitting BASE is comprised of a vinyl backing with velcro loop on top with leather lace facing and 3/4" leather rear strap aroung the butt of the stock. A nylon lace holds it securley to the butt stock. The TOP PAD consists of an outer latigo leather surface and a velcro hook under layer with a propriatary inner layer of a heat activated resin material. This is then heated to 260 degrees and molded to form the pad which is hardened when cooled. This pad can be moved up and down on the base as needed for height or for cast on or cast off as needed to perfectly align your eye with the sights or scope. A notched gauge on either side of the base allows repeatability of position for top pad to coinside with the height of the rear sight or scope when changing distance of targets. This riser is designed to fit full size butt stocks and will be too big for small petite butt stocks like Henry rimfire lever guns and other rimfire and youth guns with petite butt stocks. We suggest using our model LO-3000 which offers a choice of a standard size base or a small base. See the diagram to deside which base you will need.
