Osuma Blaser QD base, without rings

• Blaser quick-detach interface: The base uses the Blaser mounting system for fast removal and reinstallation, making it practical for hunters who switch optics or transport the rifle frequently while keeping the setup consistent.
• Base supplied without rings: This configuration gives more flexibility when building a scope mounting system, especially for shooters who already own compatible rings or need a specific ring height and tube size.
• Steel construction: A steel base adds rigidity and wear resistance at the locking surfaces, which matters on a mount that may be attached and detached repeatedly in field use.
• 0 MOA inclination: The flat mounting geometry suits general hunting and everyday rifle setups, keeping the optic aligned for standard zeroing distances without adding elevation bias.
• Made in Finland: Finnish manufacture reflects a design approach focused on practical hunting use, dependable machining, and compatibility with common European rifle and optic combinations.

About the Blaser Series

Osuma Blaser mounts are built around the Blaser quick-detach mounting system, a format valued by hunters who want a secure optic interface that can be removed and reinstalled with minimal fuss. Within the Osuma lineup, this series covers several mounting solutions for Blaser users, including complete mounts with rings, rail-mount variants, and base options for more specialized setups. That makes the series relevant both to shooters starting from scratch and to those adapting an existing optic to a Blaser rifle.

The defining idea behind the series is modularity. Rather than forcing one ring size or one optic format, the Blaser family is arranged to support different scope tubes, rail-mounted optics, and accessory combinations. The design philosophy is straightforward: a solid mechanical connection, easy handling in the field, and compatibility with the mounting patterns commonly used on European hunting rifles and optics. For users who move between driven hunting, stalking, and range work, Osuma’s Blaser platform offers a practical way to configure the rifle around the optic instead of the other way around.

About the Osuma Blaser QD base, without rings

The Osuma Blaser QD base, without rings is aimed at shooters who want the speed of a quick-detach Blaser mount but prefer to choose their own upper mounting solution. That makes it especially useful when an optic already has compatible rings available, when a particular ring height is needed, or when the rifle is being set up around a specific scope body and bolt clearance requirement. Instead of locking the user into one complete mount configuration, this base leaves the system open for a more tailored build.

The use of steel construction is important here because the base is the part that takes the repeated clamping and unclamping loads of a detachable mount. In practical terms, that helps the contact points stay consistent over time and supports a stable interface between rifle and optic. The 0 MOA inclination also tells you what this base is for: a straightforward hunting or general-purpose rifle setup rather than a mount intended to add built-in elevation for extended long-range dialing. On a Blaser rifle, that makes it a sensible choice for conventional zero distances and everyday field use.

Because it is supplied without rings, this model suits experienced users who want to assemble the mounting system around their preferred optic hardware. It is a simple component, but an important one: it provides the foundation for a clean, adaptable, and repeatable scope mounting arrangement on the Blaser platform.

About Osuma

Osuma’s history goes back to the early 1990s, when the company owner developed his first scope mounts for his own hunting and benchrest shooting needs. Osuma is based in Finland, and its products are designed and manufactured there, reflecting the brand’s long focus on practical rifle equipment for demanding field use. The company later passed from father to son, while keeping scope mounting as its central area of expertise.

Today, Osuma specializes in rifle scope mounting and offers a broad range that includes scope mounts, scope rings, rail mounts, red-dot and holosight mounts, and suppressors. Its catalog also covers multiple mounting standards, including Blaser systems, which is directly relevant to this base. That background gives Osuma a strong position in a product category where fit, repeatability, and mechanical reliability matter more than unnecessary complexity.
