Product DescriptionXS Ghost Ring WS hunting sights deliver faster target acquisition and improved accuracy in a rugged, all-steel design. This set fits Ruger/Marlin 336 and 1894 models that use a front sight blade mounted in a ramp screwed to the barrel (not compatible with barrels where the front blade is dovetailed directly into the barrel). The rear ghost ring is fully adjustable for windage and elevation and ships with two interchangeable apertures-0.230" and 0.191"-to match different lighting conditions. The XS White Stripe front post replaces the existing blade and ramp, providing a high-contrast white-on-black sight picture. Mounting hardware is included. Use with the XS Lever Rail; the sight set does not work alone or with the Lever Scout Mount.Product Highlights Fast-acquisition ghost ring rear with wide field of view White Stripe front post for high-contrast visibility in varied light Fully adjustable windage and elevation; two aperture sizes included Durable steel construction; hardware included for installation Fits Marlin/Ruger 336 and 1894 models with ramp-mounted front sight Specs Compatibility: Marlin/Ruger 336 and 1894 rifles with front sight installed in a ramp screwed to the barrel; not for dovetail-mounted front blades Apertures Included: 0.230" and 0.191" inside diameter Construction/Finish: Steel; matte finish Front Sight Color: Black body with painted white stripe face Rear/Front Blade Heights: Rear 0.49 in; Front 0.25 in Installation Notes: If the receiver is not drilled and tapped, this must be done to install the rear sight Country of Manufacture: United States of America Includes: Mounting hardware and thread locker UPC: 647533001908 Manufacturer Part Number: ML-0025-5 Brand Name: XS Sights Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
