Leupold 54229 1-Piece Base For Marlin 336, 336T, 35, 36, 36A, 375,444, 1895, 9,45 Quick Release Style Black Matte Finish

The Leupold 54229 is characterized by its exemplary machining tolerances, forming the core of its unique lever mechanism. This patented design operates based on a forward rotation of the lever. Upon this action, an eccentric on the lever shaft interacts with the ring's base. Consequently, the ring is drawn down and forward onto its base, thus securely establishing it within its designated \"zero\" position.
