XS Sight Systems Lever Rail Ghost Ring WS Features The XS Sight Systems Lever Rail Ghost Ring WS is machined from lightweight anodized aluminum to exacting Picatinny rail specifications giving Marlin 308MX owners the ability to mount an optic directly over the receiver or further forward for a scout scope or red dot configuration. The ghost ring rear sight is fully adjustable for windage and elevation and ships with two apertures a .230 and a .191 inside diameter so shooters can select the aperture that best suits the lighting conditions they are hunting or shooting in. The large ghost ring opening provides a wide field of view for fast target acquisition a benefit for shooters tracking moving game through brush. Because the rear sight moves from the barrel to the receiver some re-zeroing is expected after installation. The XS White Stripe front sight replaces the factory blade and ramp featuring a blued steel body with a painted white stripe face that stands out clearly against dark or light backgrounds alike. Installation requires removal of the factory rear sight and all mounting screws should be torqued to 20 inch-pounds to avoid fracturing or breaking hardware during installation. Alternate front sight heights are available for shooters whose zero requires a different sight picture. This rail and sight combination does not fit Marlins with an octagon barrel so Marlin 308MX owners with a standard round barrel configuration will get the most direct benefit from this upgrade.
