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 SVD, it will fit many other rifles - Mosin-Nagant, Mauser and all their modifications. Inner diameter of the pad is 120 mm long and 35 mm wide. For a narrower inner diameter check the AK version. Highly recommended for target shooting; there may be less expensive butt pads on the market but none of this quality for the SVD, Mosin, Mauser, Lee Enfield and many other rifles. This is a DEFINITE BEST CHOICE!
