The XS Lever Rail Ghost Ring WS upgrades the Henry .45-70 to allow for mounting of an optic in multiple positions and adds rugged all-steel back up iron sights. Fits Henry .45-70 rifles with steel receiver, round barrel and front sight dovetailed into the 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. XS Ghost Ring rear sight is fully adjustable for windage and elevation and comes with two apertures, .230″ and .191″ inside diameter, for different lighting conditions. Installation requires removal of factory rear sight. All screws torque to 20 INCH-pounds; over-torquing can fracture or break screws.
