This benchrest forend adaptor quickly converts almost any stock into a benchrest stock. No modifications to your stock are necessary. Simply insert the appropriate screw (included) through the forend adaptor and thread it into the front sling stud hole. The side plates adjust inward to configure to the forend design of your rifle. Cork material protects the stock finish. The 3 inches wide bottom plate is made of solid UHMW, which has a low coefficient of friction. Accepts forend widths from one and one fourth inches to two and three eight inches.
