Leupold 2pc Steel Mount For Ruger American Rimfire Rifle, Matte Black - 170489

The Leupold steel standard bases are the most versatile of any mounting. The rear ring is secured by windage adjustment screws, allowing the scope's internal adjustments to be reserved for precise sight-in. Additionally, shims can be used for gross elevation adjustment, reserving the scope's elevation adjustment for bullet drop compensation dial applications. Fits: Ruger American rimfire rifles.
