The XS Sights Lever Rail for Marlin 336/.308 Marlin Express (brand part no. ML-6004R-N) gives a Marlin 336-pattern lever gun a full-length Picatinny rail interface for mounting a scope or red dot, replacing limited factory sight options with a standard optics-ready platform. Machined from aluminum as a one-piece base and finished in black matte to match the rifle, the rail is built to the receiver’s specific contour for a precise, no-gunsmithing fit. At 13.6 inches long, it runs the length of the action to give shooters flexibility in where they position an optic for their preferred eye relief. It accepts Weaver-style rings, which are not included, so plan to pair it with a ring set sized for your scope or optic.
