The XS Lever Rail upgrades the Marlin 1895 to allow for mounting of an optic in multiple positions. Fits Marlin 1895 with round barrel. Lightweight, anodized aluminum rail is machined to Picatinny specs and allows scope mounting directly over the receiver, or forward for scout scopes or red dot sights. Installation requires removal of factory rear sight. All screws torque to 20 INCH-pounds; over-torquing can fracture or break screws.
