Leupold BackCountry Picatinny Rail for Vanguard SA (20 MOA)

• 20 MOA cant: Built-in forward inclination preserves more scope elevation for long-range dialing, which is especially useful when a rifle and optic are being set up for extended-distance shooting.
• Picatinny cross-slot interface: The rail accepts both Picatinny- and Weaver-style rings, giving broader ring compatibility and making future optic changes simpler.
• 7075-T6 aluminum construction: This high-strength alloy keeps weight down while providing the rigidity needed to maintain a stable scope-to-action connection under recoil and field use.
• One-piece rail design: A single base creates continuous mounting space, helping with ring placement flexibility when fitting scopes with different tube lengths and eye-relief requirements.
• Weatherby Vanguard Short Action fit: The rail is shaped for this action pattern, giving a direct mounting solution for rifles that share the Vanguard SA footprint.

About the Leupold BackCountry Bases Series

Leupold BackCountry Bases sit within the company’s lightweight hunting and shooting mount range, offering a practical balance of low mass, cross-slot versatility, and rifle-specific fit. The series includes model-specific variants for actions such as the Remington 700 and Winchester 70, so the mounting geometry is tailored to the rifle rather than treated as a generic solution. Within the line, Leupold offers both zero-elevation and 20 MOA versions, with the angled models intended for shooters who want to preserve more elevation travel for longer distances.

A defining feature of the series is its 7075-T6 aluminum construction, which keeps the mount light without giving up the stiffness needed for a secure optic platform. BackCountry Cross-Slot Bases also use a layout that accepts Picatinny- and Weaver-style rings, which broadens ring choice and makes it easier to move between different optic setups. In practical terms, the BackCountry series is aimed at shooters who want a mount that stays simple, trims unnecessary weight, and still supports everything from straightforward hunting optics to more dial-focused long-range riflescope setups.

About the Leupold BackCountry Picatinny Rail for Vanguard SA (20 MOA)

The Leupold BackCountry Picatinny Rail for Vanguard SA (20 MOA) is a one-piece cross-slot base made for the Weatherby Vanguard Short Action footprint, which also covers compatible actions such as the Howa 1500 SA and Smith & Wesson 1500 SA. Its main advantage is the built-in 20 MOA incline. By tilting the scope slightly forward, the rail helps preserve more of the riflescope’s internal elevation adjustment, which matters when a setup is intended for longer shots and regular turret dialing.

The rail follows the Picatinny standard and also accepts Weaver-style rings, so it gives more flexibility than a proprietary mounting pattern. That wider compatibility is useful when matching ring height, swapping optics, or moving from a hunting scope to a more precision-oriented setup. The one-piece format also provides continuous slot spacing, which makes ring placement easier when working around scope tube length, saddle position, or eye-relief needs.

Leupold builds this model from 7075-T6 aircraft-grade aluminum, a material choice that keeps the mount light while maintaining the rigidity expected from a recoil-bearing interface. In use, that means less unnecessary weight on the rifle without compromising the stable connection between receiver, rings, and optic. The matte black finish keeps the rail visually subdued and matches well with modern hunting and precision rifle builds.

About Leupold

Leupold & Volpel was founded in 1907 in Portland, Oregon by Fred Leupold and Adam Volpel. The company remains family-owned and focuses on sport optics for hunting, shooting, and outdoor use. Its product range includes riflescopes, red dot sights, binoculars, spotting scopes, rangefinders, and thermal optics, giving Leupold a long-standing presence across several core shooting and observation categories.

Leupold introduced its first riflescope, the Plainsman, in 1947, and later introduced the Duplex reticle in 1962, a design that became widely recognized in sporting optics. In 1968, the company moved its manufacturing plant and headquarters to Beaverton, Oregon, where Leupold & Stevens, Inc. is still headquartered. Today, the brand is particularly well known for its hunting-focused VX-series riflescopes and Mark-series tactical optics, along with the mounts and accessories that support them.
