Spuhr spacer

• Raises mounted interfaces: This spacer adds 4 mm/.157” of height, helping clear tall turrets or large objective housings when fitting accessories above a riflescope.
• Built for the Spuhr Interface: Designed for the Spuhr ISMS Interface, it keeps accessory mounting consistent with the same direct-attach system used across compatible ISMS mounts.
• Light aluminium construction: The aluminium body adds useful stand-off height without introducing unnecessary bulk, which helps preserve the balance of a rifle setup.
• Rattle-free fit: Used within the Spuhr interface system, the spacer supports a secure accessory installation that stays properly aligned under field use and recoil.
• Simple installation: The spacer is supplied with screws, so it is ready to install as part of an ISMS accessory stack without needing separate hardware.

About the Spuhr Accesories Series

Spuhr Accesories are built around the company’s ISMS scope mount platform, giving shooters a modular way to add capability without changing the core mount. The series includes direct interfaces for miniature sights, interface spacers, Picatinny rails and other adapters that let the user configure a riflescope mount for a specific role. That can mean adding a red dot sight, an angle cosine indicator, a laser or another support accessory while keeping everything attached to the mount rather than the rifle’s handguard or receiver.

A defining feature of the series is the Spuhr Interface, which uses two threaded holes with dual conical parts to create a secure, repeatable connection. In practice, this gives the system a compact footprint and a stable fit that suits hard-use hunting optics and precision shooting setups alike. Across the range, the design philosophy is straightforward: keep accessories close to the optic, maintain a clean profile, and allow the shooter to build a more capable mounting solution with purpose-made parts rather than improvised adapters.

About the Spuhr spacer

The Spuhr spacer is a simple but useful mounting accessory for shooters who need a little more clearance when building out an ISMS-based riflescope setup. By adding 4 mm/.157” of height between compatible interface components, it helps position an accessory above surrounding scope features that might otherwise interfere with fitment. This is especially relevant on riflescopes with prominent elevation turrets or larger objective housings, where even a small increase in stand-off height can make the difference between a clean installation and a cramped one.

Because it is made for the Spuhr ISMS Interface, the spacer works within the same direct-mount system used across the broader ISMS accessory family. That matters in practice because it lets the user preserve the compact, centered mounting style that Spuhr mounts are known for, instead of resorting to taller or less integrated third-party solutions. The aluminium construction keeps weight low while still matching the material and design language of the mount system itself.

As a mounting accessory for riflescopes, this spacer is best understood as a fitment tool rather than a universal adapter. Its role is to create the extra room needed for a cleaner accessory layout, while keeping the installation secure and mechanically consistent with the rest of the Spuhr interface ecosystem.

About Spuhr

Spuhr i Dalby AB was founded by Håkan Spuhr in 2007 and is based in Löddeköpinge, Sweden. The company focuses on firearm optics mounts and weapon upgrade components, with a product range that spans scope mounts, chassis systems and platform-specific upgrades. Spuhr is particularly closely associated with the Ideal Scope Mount System (ISMS), introduced in 2010, which established the company’s approach to integrating accessory attachment points directly into the mount.

That emphasis on modularity and mechanical fit carries through the wider range, including upgrade kits for the HK G3 and MP5 platforms and the Ideal Chassis System (SICS) for bolt-action rifles. In the optics-mount category, Spuhr has built its reputation around precise machining, repeatable alignment and practical accessory integration for professional, competition and field rifle setups.
