The Leupold BackCountry series comes in cross-slot and ringmount styles that accept both Picatinny and Weaver-style rings. This cross-slot model is specifically designed to fit any riflescope with a 34mm maintube. Constructed with incredibly lightweight 7075-T6 aluminum and a milled in recoil lug and low-profile keeper screw, the BackCountry series is one of our lightest and most rugged hunting-style mounts yet.
