Osuma Zeiss ZM/VM Rail, Optilock Base

• ZM rail to Optilock conversion: lets a riflescope with a Zeiss ZM/VM rail sit on an existing Optilock Ø 7 mm interface, so a rail-mounted optic can be used without changing the whole mounting system.
• Rigid fixed-mount layout: the one-piece adapter concept gives a stable connection between scope and base, which helps maintain alignment and supports repeatable zero in normal hunting use.
• 0 MOA inclination: keeps the scope level in a neutral mounting position, making it a practical choice for general-purpose hunting rifles where no built-in cant is required.
• Aluminium construction: keeps weight low while still providing the stiffness needed for a scope-mount component, so the rifle stays better balanced and easier to carry.
• Made in Finland: designed and manufactured in Finland for shooters who value straightforward, purpose-built mounting hardware with a focus on fit and practical field use.

About the Osuma Blaser Adapters Series

Osuma Blaser Adapters are built around a simple idea: converting a conventional scope-mounting arrangement into a Blaser-style interface so compatible rifles can use that quick-detachable mounting concept. In Osuma’s lineup, this series serves shooters who want the handling and convenience of a Blaser-type mount without changing the rifle itself. The family is intended mainly for hunting rifles and practical field use, where fast optic changes and dependable return to zero matter more than unnecessary complexity.

The series includes fitments for several rifle platforms, with versions listed for models such as Tikka T3/T3x, Sako TRG 21-42 and Howa 1500 LA. Osuma’s design approach is mechanical and application-driven: the adapters attach to pre-drilled mounting points and are meant to provide a secure, repeatable connection for a detachable sight setup. Across the range, the emphasis is on compatibility, straightforward installation and preserving zero when changing optics. That makes the series relevant to hunters who use more than one sighting system or want a cleaner way to move between optics on the same rifle.

About the Osuma Zeiss ZM/VM Rail, Optilock Base

The Osuma Zeiss ZM/VM Rail, Optilock Base is a fixed mount adapter for shooters who already use an Optilock base and want to fit a scope with a Zeiss ZM / VM rail. Instead of replacing the lower mounting platform, this model converts the upper interface, which is a practical solution when a preferred riflescope comes with a rail rather than a conventional tube. It is especially useful on hunting rifles where the owner wants to keep an established base system while moving to a rail-mounted optic.

The mount uses a 0 MOA configuration, so the scope sits in a neutral position suited to general shooting distances and ordinary hunting applications. With KR 0.0 mm extension, the layout stays compact and centered, which helps when the goal is a clean, low-profile installation rather than extra fore-and-aft offset. Because windage is not adjustable in the mount itself, the design stays simple and solid, relying on proper base alignment instead of adding extra moving parts.

Its aluminium body keeps the adapter light, while the black finish gives it a subdued appearance that matches most rifles and optics. In practice, this mount is about compatibility and efficiency: it bridges a Zeiss-style inner rail and the Optilock Ø 7 mm interface, allowing a secure and tidy installation for shooters who prefer the handling and clamping style of rail-mounted scopes.

About Osuma

Osuma is a Finland-based brand focused primarily on rifle scope mounting. Its history goes back to the early 1990s, when the owner developed the first mounts for his own hunting and benchrest shooting needs. The company later passed from father to son, while keeping the same practical emphasis on products shaped by real shooting use rather than broad lifestyle branding.

Today, Osuma’s range includes more than 150 products, covering scope mounts, scope rings, rail mounts, red-dot and holosight mounts, suppressors and accessories such as the Trigger Widener. The brand is known for designing and manufacturing its products in Finland, and its aluminium scope rings use an anodized surface for durability. Within this category, Osuma is best understood as a specialist maker of mounting solutions for hunters and shooters who need platform-specific fit and straightforward mechanical design.
