The XS Ghost Ring WS hunting sights offer improved accuracy and faster sight acquisition in a rugged all-steel design. Fits Ruger/Marlin 336, 1894, & 30AS with existing front sight blade and ramp that is screwed onto the barrel. Does not fit models with front sight blade dovetailed directly into the barrel. XS Ghost Ring WS is fully adjustable for windage and elevation and comes with two apertures, .230″ and .191″ inside diameter, for different lighting conditions. The large Ghost Ring affords great field of view for fast target acquisition. The XS White Stripe (WS) front sight replaces the existing blade and ramp and features a blued steel body with a painted white stripe face. White on black front post is highly visible in all lighting conditions, as well as provides contrast against any color background. Due to moving the rear sight from the barrel to the receiver, some zeroing issues might arise. Use alone or with Lever Scout Mount. Does not work with Lever Rail.
