The Leupold BackCountry series comes in cross-slot and ringmount styles that accept both Picatinny and Weaver-style rings. This ringmount is specifically designed to fit a Browning AB3. Constructed with incredibly lightweight 7075-T6 aluminum, the BackCountry series is one of our lightest and most rugged hunting-style mounts yet. The Backcountry ringmount is machined with traditional styling and details, and features an integrated base and ring to fit specific rifle receivers.
