Leupold STD One-Piece base, Ruger 1022

• Steel one-piece construction: The solid steel base adds rigidity between receiver and optic, helping the scope stay aligned through repeated use while giving the Ruger 10/22 a durable mounting platform.
• STD mounting interface: Built for the Leupold Standard (STD) system, this base works with matching STD rings and supports a traditional low-profile scope setup for rimfire rifles.
• Windage-adjustable STD design: The front dovetail and rear windage-screw arrangement of the STD system allows lateral alignment during bore sighting, reducing the need to use up scope adjustment for basic mounting correction.
• Ruger 10/22-specific fit: Made specifically for the Ruger 10/22, it provides a direct, model-matched base that simplifies installation and supports dependable scope positioning.
• Made in the USA: Domestic manufacturing and Leupold’s long experience with sporting optics and mounts make this base a practical choice for shooters who want proven machining and consistent fit.

About the Standard (STD) Series

Leupold Standard (STD) bases and rings are designed as a traditional steel mounting system for shooters who want a secure scope installation with more flexibility than a simple fixed ring-and-base arrangement. In Leupold’s mount lineup, the STD series sits as a long-established option for sporting rifles, combining a classic appearance with practical adjustment features that still matter in the field.

A defining feature of the system is its front dovetail engagement paired with a rear windage-adjustable ring mount. In practice, that lets the installer correct left-right alignment during bore sighting at the mount, helping preserve more of the riflescope’s internal adjustment range for zeroing and trajectory compensation. The series is intended for hunting rifles, rimfires, and general sporting use where a low-profile steel mount is preferred over bulkier tactical rail systems.

Leupold builds STD components to work as a matched system, with rings offered in multiple heights and bases shaped for specific firearms. The result is a mounting family known for solid steel construction, a clean fit to the rifle, and a practical balance between strength, adjustability, and traditional styling.

About the Leupold STD One-Piece base, Ruger 1022

The Leupold STD One-Piece base, Ruger 1022 is a firearm-specific scope base made for the Ruger 10/22 and the Leupold Standard mounting system. Its one-piece layout gives the rifle a stable platform for a rimfire optic while keeping the installation straightforward for shooters who want a conventional scope setup rather than a cross-slot rail.

The use of steel construction is important on a base like this because it prioritizes rigidity and long-term durability at the point where the optic meets the rifle. On a 10/22 used for target shooting, small-game hunting, or general range work, that helps maintain consistent scope alignment over time. Because it is part of the STD system, the base works with matching STD rings, whose front dovetail and rear windage screws allow lateral correction during mounting. That practical feature can make bore sighting easier and helps keep more of the riflescope’s internal windage and elevation travel available for actual zeroing.

This model is also a good fit for shooters who prefer a lower, cleaner mounting arrangement. Instead of adding the extra height and visual bulk of a rail, the base keeps the rifle closer to a classic sporting profile. For a Ruger 10/22 set up with a compact hunting or target scope, that means a tidy installation, dependable support, and compatibility with a proven Leupold ring-and-base system.

About Leupold

Leupold & Volpel was founded in Portland, Oregon, in 1907 by Fred Leupold and Adam Volpel. The company later became known for sport optics and remains closely associated with hunting and shooting equipment made in the United States. Leupold & Stevens, Inc. is headquartered in Beaverton, Oregon, where the company moved its manufacturing plant and headquarters in 1968.

Leupold is a family-owned company that develops optics for hunting, shooting, and outdoor use, including riflescopes, red dot sights, binoculars, spotting scopes, rangefinders, and thermal optics. Its history in riflescopes goes back to 1947, when it introduced the Plainsman, and the company later introduced the Duplex reticle in 1962. That long involvement in sporting optics is directly relevant to products like scope bases and rings, where fit, repeatability, and durability matter just as much as the optic mounted above them.
