Leupold STD Winchester 70 Long-Range RH-LA 1-Piece Matte Base LU51736

The Leupold STD Winchester 70 Long-Range RH-LA 1-Piece Matte Base is built for shooters who demand both rugged strength and long-range precision. Machined from hardened steel, this base stands up to repeated recoil yet keeps your scope rock-solid under serious use. It features a built-in 15 MOA cant, giving you extra elevation for dialing in distant targets while preserving your scope’s internal elevation travel for finer adjustments.

The rear ring secures with windage screws, allowing you to bore sight laterally without eating into your scope’s internal adjustment range. For gross elevation changes, you can drop in shims under the front ring — a smart way to reserve your scope’s turret for BDC or long-distance dialing. This system makes your setup both flexible and rugged, built for long-range performance.

With a weight of just 2.8 oz, it stays light on your rifle, yet its steel construction doesn’t compromise on toughness. The matte black finish cuts glare, resists corrosion, and maintains a low-profile, no-gloss look that won’t catch unwanted attention. Torque specs are solid, too: 22 in-lbs for the base-to-receiver screws and 45 in-lbs for the windage screws, giving you confidence your mount stays tight.

Because this base uses Leupold’s STD mounting system, it mates seamlessly with STD rings — setting you up with a robust, dependable platform that’s as at home on precision rifles as it is on field guns. Whether you’re zeroing in for long-range matches or chasing game in unforgiving terrain, this one-piece base delivers a reliable, rugged solution you can trust.
