Not a recoil pad, per se, but a recoil reduction system: Ken Rucker's "Bump Buster." It is a hydraulic recoil reduction system. You can adjust the amount of recoil reduction desired and the LOP. In addition you can add your favorite pad, although Ken recommends a KICK EEZ pad with his system. They come in standard and magnum flavors. I have ordered a standard for my .30-06 and magnums for my 9.3 x 62 and .375 H&H. Since some grinding/fitting is required, it is best to have it installed directly by Ken or your smith.
