This recoil pad is made from polyurethane and can be mounted on original wooden buttstock. Pad is fixed by 2 retaining bolts. With this recoil pad overall stock length will increase by 5 cm. Thank to elastic reinforcement ribs it damps major part of recoil. Recoil pad mounts in less than 5 minutes; you just need to remove original metal plate, fixed by 2 self-tapping screws, and replace it with your new recoil pad.
