Spuhr Tri-Rail, short

• Three-sided accessory mounting: The short Tri-Rail adds Picatinny attachment points on the top and both sides of a compatible scope mount, making it easier to position lights, lasers or other support equipment without changing the main optic setup.
• Built for 34 mm ISMS mounts: This model is shaped to fit around the front ring on 34 mm ISMS scope mounts, giving a secure and tidy way to expand a riflescope mounting system while keeping accessories close to the optic.
• Compact 70 mm format: Its short length keeps the mounting area focused where it is needed, helping preserve rifle balance and avoiding unnecessary bulk on a precision or tactical optics setup.
• Aluminium construction: The aluminium body keeps weight manageable while providing the rigidity expected from a mount accessory that may carry aiming or observation devices in field use.
• Includes mounting screws: Supplied screws allow the Tri-Rail to be installed as intended on the compatible mount, simplifying integration into an existing Spuhr system.

About the Spuhr Accesories Series

Spuhr Accesories are built to expand the capability of the company’s mounting systems rather than replace them. The series centers on add-ons designed to attach optical equipment and support devices to ISMS scope mounts, either through direct interfaces or through added Picatinny rail sections. That approach gives the user a modular way to configure a rifle around a specific task, whether the goal is adding a backup sight, an angle cosine indicator, a laser, an illuminator or a night-vision component.

A defining feature of the range is the Spuhr Interface, which uses two threaded holes with dual conical parts for precise and repeatable attachment. Alongside these direct-fit solutions, the series also includes interface spacers, ACI interfaces and sight-specific adapters for footprints such as Aimpoint Micro, Trijicon RMR, Docter and Delta Point. Within that lineup, the short Tri-Rail serves shooters who want the flexibility of standard Picatinny-compatible accessories on a compact ISMS-based platform.

About the Spuhr Tri-Rail, short

The Spuhr Tri-Rail, short is a mounting accessory for shooters who need more than a single attachment point around their riflescope. By adding Picatinny interfaces on the top and both sides of a compatible mount, it creates space for third-party accessories that use standard Picatinny clamps. In practice, that means a precision rifle or tactical optics setup can carry mission-specific equipment without moving away from the main optic or adding a separate handguard-mounted solution.

This short version is designed to fit around the front ring on a 34 mm ISMS scope mount, which keeps the added accessory positions close to the optic and central to the rifle. That placement is useful when the accessory needs to stay aligned with the sighting system or remain easy to reach and observe from the shooting position. The 70 mm/2.76" length keeps the assembly compact, so the rifle gains mounting flexibility without becoming unnecessarily long or cluttered.

The body is made from aluminium, a practical choice for a component that must remain rigid while avoiding excessive added mass. With a stated weight of 100.00 g, it suits users who want to expand a riflescope mount in a controlled way rather than build a large external rail structure. The matte finish also matches the restrained, functional style typical of Spuhr mounting components.

About Spuhr

Spuhr i Dalby AB was founded by Håkan Spuhr in 2007 and is based in Löddeköpinge, Sweden. The company focuses on the design and manufacture of firearm optics mounts and weapon upgrade kits, with a reputation built around practical modularity and precise mechanical fit. A key milestone came in 2010, when Spuhr introduced the Ideal Scope Mount System (ISMS), a mount concept that integrates scope mounting with accessory attachment points.

Beyond scope mounts, Spuhr has also developed products such as upgrade kits for the HK G3 and MP5 platforms, the Ideal Chassis System (SICS) for bolt-action rifles and specialized mounts including 40 mm grenade launcher sight mounts. That background is relevant here because the company’s accessories follow the same design logic as its core mounts: strong interfaces, clean integration and a system-based approach to configuring a rifle.
