The Kinetic Research Group Recoil Pad is made from a proprietary material that is comfortable, durable and helps absorb recoil. It has a pleasing appearance and is lighter than the buttpads used on some previous KRG chassis. This one displays the KRG logo on the back and will retrofit to all KRG chassis. It's generally a Remington 700 pattern so it fits some other stocks. Fits: All KRG chassis, some stocks that use Remington 700 pattern recoil padsWon't fit the Rem 700 stocks that are mostly hollow plastic
