Leupold STD Two-Piece base, Winchester XPR RVR

• Two-piece steel construction: The steel build gives this base the rigidity needed for a stable scope-to-rifle connection, while the two-piece layout keeps the loading and ejection port more open for easier access on a hunting rifle.
• STD windage-adjustable system: Leupold’s Standard mounting pattern uses a front dovetail and rear windage screws, allowing lateral alignment during bore sighting and helping preserve more of the scope’s internal adjustment range.
• Winchester XPR-specific fit: This base is made for the Winchester XPR platform, so it provides the correct interface for a secure installation instead of relying on a more generic mounting solution.
• 0 MOA base cant: A flat base keeps the optic in a neutral position, which suits general hunting and everyday field use where a straightforward zero is more important than added elevation bias.
• Compatible with Leupold Standard rings: It matches the Leupold STD ring system, making it easy to build a traditional riflescope setup with ring heights and components already established within the same mounting family.

About the Leupold STD Bases Series

Leupold STD Bases are built around a traditional hunting-style mounting system that has remained popular because it is simple, strong, and easy to match to a wide range of sporting rifles. In Leupold’s lineup, the STD family sits as a classic steel option for shooters who want a proven base-and-ring arrangement rather than a full rail or a more tactical cross-slot design. The system is offered in one-piece and two-piece configurations, with model-specific fitments for different rifle actions.

A defining feature of the STD design is its front dovetail ring interface combined with rear windage screws. In practice, that gives the installer some lateral adjustment during bore sighting, which can help center the scope more efficiently and leave more internal adjustment available for zeroing. The series is also known for its steel construction, which suits hard field use and complements traditional hunting optics well. Some long-range STD variants add elevation cant, while standard 0 MOA versions remain focused on straightforward sporting applications. Across the range, the emphasis stays on rifle-specific fit, dependable alignment, and a conventional look that pairs naturally with bolt-action hunting rifles.

About the Leupold STD Two-Piece base, Winchester XPR RVR

The Leupold STD Two-Piece base, Winchester XPR RVR is a rifle-specific mounting solution for the Winchester XPR, built for shooters who want a traditional steel base with the flexibility of Leupold’s Standard system. Its two-piece configuration keeps the receiver area more open than a one-piece base, which is useful on a practical hunting rifle where access to the action matters during loading, unloading, and routine handling.

This model uses the established STD front dovetail and rear windage screw arrangement, a design that remains relevant because it helps align the scope laterally during installation. That matters in practice: when the base and rings allow fine windage correction at the mount, the riflescope can retain more of its internal adjustment range for zeroing and trajectory tuning. For a field rifle, that can make setup cleaner and reduce unnecessary strain on the optic’s erector system.

The base is made from steel, which gives it the stiffness and durability expected from a hunting optic mount that may see recoil, weather, and repeated transport. With 0 MOA inclination, it is aimed at conventional zeroing distances rather than specialized long-range elevation bias. It is also designed to work with the Leupold Standard (STD) ring family, making it a sensible choice for a classic riflescope installation on Winchester XPR short-action and long-action rifles.

About Leupold

Leupold & Volpel was founded in Portland, Oregon, in 1907 by Fred Leupold and Adam Volpel. The company later introduced its first riflescope, the Plainsman in 1947, and became widely known for practical riflescope design, including the Duplex reticle introduced in 1962. In 1968, Leupold moved its manufacturing plant and headquarters to Beaverton, where the company remains based today.

As Leupold & Stevens, Inc., the business is still family-owned and focuses on sport optics for hunting, shooting, and outdoor use. Its range includes riflescopes, red dot sights, binoculars, spotting scopes, rangefinders, and thermal optics. Within the shooting world, Leupold is especially associated with hunting optics and tactical riflescopes such as the VX-series and Mark-series, alongside the mounts and accessories needed to build a complete rifle setup.
