Osuma Swarovski SR Rail, Optilock Base

• SR rail to Optilock adaptation: This mount lets a riflescope with a Swarovski SR rail sit on an existing Optilock base, making it easier to use a rail-equipped optic without changing the rifle’s lower mounting interface.
• 0 MOA alignment: The 0 MOA configuration keeps the scope in a neutral position, which suits general hunting and everyday sighting setups where no built-in elevation cant is needed.
• Aluminium construction: The mount uses an aluminium body to keep weight down while still providing the rigidity needed for a stable optic-to-rifle connection.
• Fixed, non-windage design: With no windage adjustment built into the mount, the setup stays mechanically simple and solid, reducing extra moving parts in the interface.
• Made in Finland: Designed and manufactured in Finland, this mount follows Osuma’s practical approach to rifle mounting hardware for hunting and range use.

About the Osuma Rail Mounts Series

Osuma Rail Mounts are built to adapt riflescopes with integrated mounting rails to a wide range of rifle interfaces. In this series, Osuma focuses on the two rail standards most commonly seen on premium European optics: Zeiss ZM/VM and Swarovski SR. That makes the range especially relevant for hunters and shooters who prefer the clean profile and repeatable positioning of rail-mounted scopes over traditional ring setups.

The series sits within Osuma’s broader scope-mount lineup and covers several rifle-side attachment standards, including 11 mm, Tikka 17 mm, Sako, Picatinny and Optilock solutions. This gives the family a practical role: it helps match premium rail-equipped optics to rifles that may already have an established mounting platform. The design philosophy is straightforward and field-oriented, with mounts intended to provide a secure mechanical connection without unnecessary complexity. Osuma also offers both ZM and SR variants in the range, and some versions are tailored to specific applications such as AR-style Picatinny setups. Across the series, the emphasis is on compatibility, simple installation logic and Finnish-made construction.

About the Osuma Swarovski SR Rail, Optilock Base

The Osuma Swarovski SR Rail, Optilock Base is a fixed mount designed for shooters who already use an Optilock base and want to fit a riflescope with a Swarovski SR rail. Instead of replacing the rifle-side mounting system, this model works as the upper interface between the existing base and the rail-equipped optic. That makes it a sensible option for hunters who are moving to a premium European rail-mounted scope while keeping a familiar base arrangement on the rifle.

The mount uses a 0 MOA layout, so it keeps the optic in a neutral alignment suited to general-purpose zeroing distances rather than adding elevation bias for extended-range dialing. Its non-adjustable windage construction also reflects a simple, rigid approach: the mount is made to hold the scope securely rather than introduce extra adjustment points into the system. In practice, that can be an advantage for users who value a clean, dependable interface with fewer variables in the mounting assembly.

With its black aluminium construction, the mount keeps weight low while remaining appropriate for regular field use. The material choice also suits a compact upper assembly where unnecessary bulk would work against the handling of a hunting rifle. As part of Osuma’s rail-mount offering, this model is aimed at practical compatibility: it bridges the gap between the Swarovski SR rail standard and the Optilock Ø 7 mm interface used below, creating a tidy solution for a specific but common mounting requirement.

About Osuma

Today, Osuma’s range includes scope mounts, scope rings, rail mounts, red-dot and holosight mounts, suppressors and shooting accessories. The company designs and manufactures its products in Finland, and its catalog covers a wide spread of mounting standards, including 11 mm, Tikka 17 mm, Sako, Picatinny, Optilock and Blaser systems.
