This solid rubber molded Cheek Pad / Riser is designed to fit on only straight classic styled stocks without any cheek pad incorporated onto the stock. The pad is for a permanant mount using two supplied screws and rubber plugs. The pad is predrilled. We recomend useing tape to hold the cheek pad in the desired location insuring the pad is straight and alligned properly to the comb before drilling the holes into the stock. The pad is a medium density rubber so the screw should not be driven more than half the distance through the pad. Supplied rubber plugs can be glued into the holes with super glue or rubber glue and trimmed off and the top sanded level with a 400 grit sand paper. Pad is for right handed shooters only.
