Spuhr ACI mount (fixed mount)

• Direct ACI interface: This fixed mount gives an Angle Cosine Indicator a secure attachment point on a compatible Spuhr ISMS scope mount, keeping the indicator aligned and easy to read when shooting on steep uphill or downhill angles.
• Lightweight aluminium construction: The aluminium body adds useful functionality without adding much mass to the rifle, which helps preserve the balance of a precision or hunting setup.
• Low-profile fixed design: A fixed interface keeps the accessory close to the mount, reducing bulk and minimizing the chance of snagging on slings, packs, or barricades in the field.
• Built for riflescope systems: Designed as an accessory for riflescope mounting setups, it expands the capability of the optic mount without requiring a separate rail section or a more complex adapter arrangement.
• Swedish-made Spuhr component: Made in Sweden and matched to the Spuhr mounting ecosystem, it suits shooters who want consistent fit, finish, and mechanical compatibility across their rifle setup.

About the Spuhr Accesories Series

Spuhr Accesories are built to expand the usefulness of the company’s mounting systems, especially the ISMS platform. Rather than treating a scope mount as a simple clamp, this series turns it into a modular base for supporting equipment that helps the shooter work faster and with better information. The range includes interface spacers, Picatinny rails, ACI interfaces, and dedicated adapters for compact sights and other mission-specific add-ons.

A defining trait of the series is the way accessories attach either through a direct interface or via rail sections on the mount itself. That gives the user flexibility to add items such as angle cosine indicators, backup sights, lasers, illuminators, or night-vision accessories without resorting to improvised mounting solutions. The design philosophy is practical: keep the attachment compact, mechanically secure, and closely integrated with the optic mount so the rifle remains streamlined. For shooters using tactical optics or precision shooting setups, the series provides a clean way to add capability while preserving the strength and layout that made the ISMS system popular in the first place.

About the Spuhr ACI mount (fixed mount)

The Spuhr ACI mount (fixed mount) is a compact interface made for shooters who want to add an angle cosine indicator to a riflescope mounting setup without unnecessary bulk. In practical use, that matters most when firing at steep upward or downward angles, where corrected angle information helps the shooter apply the right hold or elevation solution. By placing the indicator directly on a compatible Spuhr mount, this accessory keeps that information visible without forcing extra rail sections or a larger mounting assembly onto the rifle.

Its fixed aluminium construction favors simplicity and rigidity. A fixed interface has no extra moving parts to manage, so it suits rifles that are carried hard in the field, used from improvised positions, or set up for repeatable precision work. The modest 100.00 g weight helps preserve rifle handling, while the matte finish keeps the appearance consistent with modern riflescope and mount combinations. Because it is intended for rifslescope accessories, it fits naturally into long-range, hunting optics, and tactical optics setups where clean integration matters as much as the accessory itself. For shooters already invested in the Spuhr ecosystem, this mount is a straightforward way to add angle-related data to the rifle without compromising the compact, organized character of the overall build.

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 reputation built around precise mechanical design and practical modularity. A key milestone came in 2010 with the introduction of the Ideal Scope Mount System (ISMS), a mount concept that combined secure scope mounting with integrated attachment points for accessories.

That emphasis on integration remains central to the brand. Alongside scope mounts, Spuhr has developed upgrade kits for the HK G3 and MP5 platforms, the adjustable SICS chassis system for bolt-action rifles, and specialized sight mounts for other weapon systems. In the optics-mount category, Spuhr is particularly known for designing mounts that do more than hold an optic in place: they also provide a stable, organized platform for supporting equipment around the riflescope.
