Osuma Tikka T3/T3x QD Base

• Quick-detach design: The QD layout lets the optic be removed and reattached quickly, which is useful when changing between sighting systems or transporting the rifle more compactly.
• Made for Tikka T3/T3x: Built for the Tikka 17 mm rail interface, this base gives a direct, model-specific fit that helps keep mounting simple and secure.
• Steel construction: A steel body adds rigidity and wear resistance in the clamping surfaces, which matters on a mount that may be attached and removed repeatedly in field use.
• Low 9.50 mm build height: The restrained height helps keep the optic close to the bore, supporting a more natural cheek weld and a more consistent shooting position.
• 0 MOA inclination: A level base is a practical choice for general hunting and everyday rifle setups where a straightforward zero is preferred over a canted long-range rail.

About the Osuma QD Series

The Osuma QD series is built around the idea of a quick-detach mounting system that remains practical for real hunting and sporting rifles. Within the Osuma lineup, these mounts sit as a flexible option for shooters who want faster optic changes than a fixed installation allows, while still keeping the setup compact and mechanically straightforward. The series is aimed at users who may alternate between different optics, remove a scope for transport, or want a mount that can be handled easily in the field.

Across the range, the emphasis is on durable metal construction, a secure fit to the relevant rifle interface, and dimensions chosen for sensible scope positioning rather than unnecessary bulk. Osuma offers QD solutions for several mounting standards, including Tikka 17 mm, Sako and Picatinny-based platforms, which makes the series relevant to both traditional hunting rifles and more modern sporting setups. In practical terms, the QD concept is about saving time and preserving handling: the rifle stays familiar, the optic can be managed more easily, and the mounting system remains purpose-built for the host platform.

About the Osuma Tikka T3/T3x QD Base

The Osuma Tikka T3/T3x QD Base is a rifle-specific mounting base made for shooters who want a quick-detach scope mounting solution on the Tikka T3 or T3x platform. Because it is designed around the Tikka 17 mm rail pattern, it suits rifles that benefit from a clean, direct-fit base rather than a universal adapter approach. That makes it a sensible choice for hunting optics where reliability, repeatable positioning and uncomplicated handling matter more than extra complexity.

Its steel construction is especially relevant on a detachable mount base, because the contact points and locking areas are exposed to repeated use over time. Steel helps the base resist wear and maintain a solid interface, which is valuable for rifles that see regular optic changes between seasons, loads or sighting systems. The 9.50 mm height keeps the setup relatively low, helping the shooter maintain a stable cheek position and keeping the optic closer to the bore line for a more natural feel behind the rifle.

The 0 MOA inclination makes this base well suited to general-purpose zeroing and conventional hunting distances. Instead of adding cant for specialized long-range dialing, it keeps the mounting geometry simple and neutral. In practice, that makes the Osuma Tikka T3/T3x QD Base a straightforward foundation for a practical rifle setup: compact, robust and matched to one of the most common Finnish hunting rifle platforms.

About Osuma

Osuma’s history dates to the early 1990s, when its owner developed the first scope mounts for his own hunting and benchrest shooting needs. That origin still fits the brand’s identity today, because rifle scope mounting remains its main area of expertise. Osuma is a Finland-based brand, and its products are designed and manufactured in Finland, with the company passing from father to son over time.

The range covers practical mounting solutions for different rifle and optic systems, including scope mounts, scope rings, rail mounts, red-dot and holosight mounts, as well as suppressors. Osuma also offers rail mounts for systems such as 11 mm, Tikka 17 mm, Sako, Picatinny, Optilock and Blaser, which reflects a strong focus on rifle-specific fit rather than one-size-fits-all hardware.
