XS Sights Ghost Ring WS - Marlin 336, 1894 & 30AS, Integral Ramp The XS Ghost Ring WS upgrades Marlin Rifles with rugged all-steel backup iron sights. 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 a 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. The white on black front post is highly visible in all lighting conditions and contrasts against any color background. Due to moving the rear sight from the barrel to the receiver, some zeroing issues might arise.
