XS Sights ML6003RN: The XS Sights Lever Rail Ghost Ring WS is an innovative upgrade for the Marlin 1894. This feature allows for the mounting of an optic in various positions and introduces robust all-steel back up iron sights. It\'s a perfect fit for Marlin 1894 models that have a round barrel with an existing front sight blade and ramp that is attached onto the barrel. Please note that it\'s not compatible with the 1894 models that have an octagon barrel. The rail, crafted from lightweight, anodized aluminum and precision-machined to Picatinny specifications, allows for the mounting of a scope directly over the receiver or forward for scout scopes or red dot sights. The XS Sights Ghost Ring WS is thoroughly adjustable for windage and elevation, and it includes two apertures, .230\" and .191\" inside in diameter, that can be used under varying lighting conditions.
