Leupold BackCountry Cross-Slot 1-Pc Scope Base Matte Black Aluminum - Marlin 336

The Leupold BackCountry Cross-Slot scope base is a precision-machined one-piece mounting platform purpose-built to fit the Marlin 336 lever-action rifle. Cut from lightweight yet exceptionally rigid 7075-T6 aluminum, this single-piece base provides a solid mounting foundation for your optic while keeping added weight to a minimum on the receiver.

Measuring 5.90" long and finished in non-reflective matte black, the BackCountry base carries Leupold's signature cross-slot design, allowing it to accept both Picatinny- and Weaver-style rings. This dual compatibility gives shooters the freedom to pair the base with virtually any modern ring set to mount their preferred optic, from a traditional variable hunting scope to a lightweight red dot or reflex sight.

Engineered for direct receiver mounting on the Marlin 336, the BackCountry installs as a single unit for a clean, low-profile setup. Rings are not included with this base, allowing you to select the height, brand, and ring style that best fit your chosen optic. Whether you run a traditional variable scope or a fast-acquisition optic, the Leupold BackCountry Cross-Slot base delivers a rugged, dependable mounting solution for your Marlin 336.
