This Butt Pad is made to military specs from high quality rubber. This slip-on style recoil pad significantly reduces recoil under any conditions. Made specifically for the AK, will fit many other rifles - inner diameter of the pad is 100 mm long and 30 mm wide. For a wider inner diameter check the SVD version. Highly recommended for target shooting; there may be less expensive butt pads on the market but none of this quality for the AK. This is a DEFINITE BEST CHOICE!
