The Leupold Marlin 1895/336 1-Piece Quick Release Base has supe close machining tolerances, which are at the heart of this patented lever mechanism. By turning the lever forward, an eccentric on the lever shaft engages the base of the ring. This pulls the ring down and forward on the base, locking it solidly into its "zero" position.
