The Leupold BackCountry cross-slot base for the Nosler M48 long action in matte (part no. 175219) uses a cross-slot system to allow versatile ring placement and maximize eye relief across a wide range of optics. Leupold machines the one-piece Picatinny rail from 7075-T6 aluminum for a durable yet lightweight platform, and the one-piece construction delivers consistent alignment and rigidity for repeatable scope zero. The base pairs with BackCountry Cross-Slot Rings or Mark 4 Aluminum rings to form a complete lightweight mounting solution. Among Nosler M48-specific scope bases, this BackCountry configuration favors hunting and precision field use.
