Ken Rucker's Speedbump Stockworks developed the Bump Buster hydraulic recoil system to tame even the heaviest recoiling rifles and shotguns. They combined the spring compression butt plate technology of the Gracoil with the hydraulic recoil absorbtion technology of Enidine into one very effective package. Also now available is the new Auto-Buster recoil system that uses a shorter dual spring system for auto loaders.
