Osuma Shield Sight Mount, 17 mm Dovetail

• Low bore-height design: The mount keeps a Shield RMS/SMS-pattern sight close to the rifle’s bore line, which helps preserve a natural cheek weld and makes fast target acquisition feel more direct.
• 17 mm dovetail fit: Built for rifles with a 17 mm dovetail interface, this mount gives a clean, dedicated way to add a compact red dot without changing the rifle’s basic handling.
• Shield RMS/SMS footprint: The platform matches Shield RMS/SMS-standard sights, making it suitable for slim reflex optics that keep overall weight and bulk to a minimum.
• Aluminium construction: The aluminium body keeps the mount light while still providing the rigidity needed for repeatable sight alignment in regular hunting use.
• 0 MOA fixed geometry: With no built-in inclination and no windage mechanism to complicate setup, the mount offers a straightforward, stable base for close- to medium-range red dot applications.

About the Osuma Holosight Mounts Series

Osuma Holosight Mounts are Osuma’s dedicated line of red dot and holosight mounting solutions for hunters who want a compact sight mounted as low as possible. In the Osuma range, this series sits alongside the brand’s broader scope-mounting systems, but it focuses specifically on lightweight reflex sights used in fast hunting situations. The design idea is simple and practical: keep the sight close to the bore so the rifle remains quick to shoulder and easy to point.

The series covers several common rifle interfaces, including 11 mm, 17 mm, Picatinny and Sako mounting standards, as well as the Blaser 2-head system. Within the line, Osuma offers versions for multiple sight patterns, including mounts for Docter Sight, Burris FastFire and Meopta Meosight-pattern optics, plus separate models for Aimpoint Micro, Aimpoint Acro and GPO/Minox sights. That broad compatibility makes the series useful for hunters who prefer a small reflex sight over a traditional scope for driven game, woodland stalking or other close-range shooting where speed matters more than magnification.

About the Osuma Shield Sight Mount, 17 mm Dovetail

The Osuma Shield Sight Mount, 17 mm Dovetail is a fixed red dot sight mount made for rifles that use a 17 mm dovetail and for compact reflex sights with the Shield RMS/SMS mounting standard. Its main advantage is not complexity but simplicity: it provides a direct, low-profile interface that lets a small red dot sit neatly on the rifle without adding unnecessary height or bulk. For hunting rifles used at short distances, that lower mounting position helps the gun come to the shoulder naturally and supports quicker sight pickup on moving game.

The mount uses a 0 MOA geometry, which suits the intended role of a compact reflex sight where a neutral, straightforward mounting angle is usually the right choice. Because there is no windage adjustment built into the mount, the design stays clean and mechanically simple, with fewer parts to add weight or complication. The aluminium construction also fits that purpose well: it keeps the assembly light enough that the rifle retains its balance, while still offering the stiffness needed for a stable sighting platform.

In practical use, this Osuma mount is best suited to rifles set up for quick shots rather than long-range correction work. It is a sensible choice for hunters who want to fit a slim Shield-pattern reflex sight to a compatible 17 mm dovetail rifle while preserving compact handling and a tidy overall package.

About Osuma

Osuma is a Finland-based brand whose history goes back to the early 1990s, when its owner began developing scope mounts for his own hunting and benchrest shooting needs. The company’s core expertise is still in rifle scope mounting, and that focus shows across a product range that includes scope mounts, scope rings, rail mounts, red-dot and holosight mounts, and suppressors. The business later passed from father to son, keeping the brand closely tied to practical field use and family ownership.

Osuma designs and manufactures its products in Finland, and its catalog now covers more than 150 items. The range includes mounting solutions for systems such as 11 mm, Tikka 17 mm, Sako, Picatinny, Optilock and Blaser, reflecting the brand’s emphasis on rifle-specific fit rather than generic hardware. That specialization has made Osuma particularly relevant to hunters and shooters who want purpose-built mounting components with straightforward mechanical design.
