Osuma 30 mm Mount for Combiguns, 11 mm Dovetail

• Quick-detachable design: The mount can be removed and reattached to the firearm, which is useful for transport, storage, or switching optics while keeping the setup practical for break-action hunting rifles and combination guns.
• 30 mm ring configuration: Built for scopes with a 30 mm main tube, this version suits many modern hunting optics and gives a secure, correctly matched interface without adapters.
• 11 mm dovetail fit for combiguns: Designed for combination guns and other break-action firearms with this rail pattern, it provides a purpose-built mounting solution where standard rifle mounts are often less suitable.
• Aluminium construction: The aluminium body keeps weight down while still offering the rigidity needed for field use, helping preserve the handling balance of lighter hunting firearms.
• 0 MOA alignment: With no built-in inclination, the mount keeps the optic in a neutral position that suits general hunting distances and straightforward sight-in.

About the Osuma Combigun Mounts Series

Osuma Combigun Mounts are a family of quick-detachable 11 mm rail mounts developed for break-action firearms and especially for combination guns. The series was designed with practical hunting use in mind, where an optic often needs to sit securely on a firearm that differs from a conventional bolt-action rifle in both action layout and mounting geometry. Osuma offers the series in several ring diameters, including 1-inch (25.4 mm), 30 mm, 34 mm, 36 mm and 40 mm, with ring-height options matched to the tube size.

A defining characteristic of the series is its focus on firearms such as Marocchi combination guns and other break-barrel or combi-gun platforms with an 11 mm rail. The quick-attachment system makes it easier to remove and reinstall the scope when needed, which is useful for transport, maintenance, or changing between sighting setups. Like other Osuma products, these mounts are designed and manufactured in Finland, and the series reflects a straightforward design philosophy: secure fit, low weight, and compatibility with the practical needs of hunting optics rather than unnecessary complexity.

About the Osuma 30 mm Mount for Combiguns, 11 mm Dovetail

The Osuma 30 mm Mount for Combiguns, 11 mm Dovetail is built for shooters who need a dedicated mounting solution for a 30 mm riflescope on a break-action firearm or combination gun with an 11 mm-style rail. That matters because these firearms often need a mount shaped around their specific rail dimensions and handling characteristics, rather than a generic ring set intended for standard receiver tops. In practice, this gives the optic a more appropriate fit on platforms such as combination guns, kipplaufs, express rifles, and other compatible models.

The mount uses a quick-detachable layout, which adds flexibility in the field. A scope can be removed for transport, cleaning, or storage and then reattached when needed, making the setup more convenient for hunters who use one firearm in different roles. The 0 MOA inclination keeps the optic level in a neutral configuration, which suits ordinary hunting distances and avoids forcing extra elevation bias into the setup. Its aluminium construction helps keep overall weight under control, an important point on lighter break-action firearms where a heavy mount can upset balance. The black finish gives the mount a subdued appearance that matches most hunting optics, while the non-windage-adjustable design keeps the structure simple and direct. This model is also compatible with a wide range of firearms, including several Baikal, BRNO, Haenel, Marocchi, Sabatti, Steyr Mannlicher, Tikka, Valmet and Antonio Zoli combigun platforms, as well as certain 12 mm dovetail variants with the appropriate profile.
