Osuma 30 mm Complete Mount, 17 mm Dovetail

• One-piece 30 mm mount: Keeps both rings aligned in a single unit, which helps maintain consistent scope positioning and simplifies installation on rifles that use a 17 mm dovetail.
• 17 mm dovetail interface: Fits rifles with the correct 17 mm rail pattern, making it a practical choice for several Tikka, Sako, Lynx and Steyr Mannlicher platforms without adding extra adapters.
• Aluminium construction: Reduces unnecessary weight while still providing the rigidity needed for a stable optic mounting platform in regular hunting and field use.
• 0 MOA inclination: Preserves a neutral scope position, which suits general-purpose zeroing and straightforward hunting setups where added cant is not required.
• Made in Finland: Reflects Osuma’s focus on precise machining and practical mount design for shooters who want dependable fit and repeatable alignment.

About the Osuma Scope Mounts Series

Osuma Scope Mounts are built around a simple idea: provide a stable, elevated mounting solution for rifles that need the scope to sit higher than usual. The series traces back to Osuma’s early mount development work in the early 1990s, and it remains focused on practical hunting and shooting applications rather than unnecessary complexity. Across the range, the mounts are made from high-grade aluminium with an anodized surface, combining low weight with the dimensional consistency needed for secure scope alignment.

The series covers both 1 inch and 30 mm scope tubes and is offered for 11 mm and 17 mm rails, making it relevant to a wide variety of sporting rifles. Depending on the model, these mounts are intended for shooters who need extra clearance for objective bells, bolt operation or rifle geometry that places the optic higher than a standard setup would allow. With listed weights in the 120 g to 155 g range and several clearance options, the family is aimed at users who want a straightforward fixed mount that balances secure hold, manageable weight and clean integration with traditional hunting rifles.

About the Osuma 30 mm Complete Mount, 17 mm Dovetail

The Osuma 30 mm Complete Mount, 17 mm Dovetail is a fixed one-piece scope mount designed for rifles that use a 17 mm dovetail and scopes with a 30 mm tube. Its layout suits traditional hunting rifles and practical field setups where a secure, uncomplicated mounting system matters more than adjustment features. Because the mount is built as a complete unit, ring alignment is inherently controlled by the mount body itself, which helps support even clamping pressure and a consistent optic position during installation.

The 0 MOA inclination makes this model a sensible choice for general-purpose zeroing distances and standard hunting applications. It keeps the optic in a neutral orientation, which is often preferable when there is no need to bias the scope for extended long-range elevation travel. The mount also has no windage adjustment, so the design stays mechanically simple and robust, relying on proper rifle and scope alignment rather than adding extra moving parts.

Its aluminium construction helps keep rifle weight under control, which is especially useful on hunting rifles carried over long distances. This model is also intended for a broad set of compatible platforms, including selected Tikka, Sako TRG, Lynx and Steyr Mannlicher rifles with the appropriate 17 mm dovetail pattern. In practice, it is a good fit for shooters who want a clean fixed mount for a 30 mm hunting riflescope without adding unnecessary bulk or cant.
