Dentler Base rail BASIS - Sako 85 XS

• Firearm-specific fit: The BASIS base rail is shaped for the Sako 85 XS action pattern, which helps create a precise interface without improvised fitting and supports a secure, repeatable optic setup.
• Part of the Dentler modular system: This base rail stays on the rifle and accepts Dentler BASIS mounting rails above, making it easier to move between different optics while keeping the mounting concept consistent.
• Steel construction: The steel body gives the rail the rigidity needed for a stable connection between rifle and optic, an important advantage for hunting rifles that are carried often and shot in varying conditions.
• Low 4.00 mm build height: The compact height helps keep the optic mounted close to the bore, which supports a natural cheek weld and a tidy overall rifle profile.
• Matte black finish: The non-reflective surface suits practical hunting use by reducing glare and visually matching modern rifle and optic setups.

About the BASIS Series

Dentler BASIS is the company’s core modular mounting platform for hunters who want a rifle-specific base combined with an optic-specific upper rail. The system is built around a simple idea: the base rail remains on the firearm, while the mounting rail remains on the optic. That layout makes the series especially relevant for shooters who use more than one sighting solution, such as a daytime riflescope, a red dot sight, or a thermal device on the same hunting rifle.

Within Dentler’s lineup, BASIS sits as the standard modular platform, while BASIS VARIO adds continuous height and windage adjustment. The regular BASIS series focuses on a repeatable, mechanically consistent connection and broad compatibility across many rifle models and optic interfaces. Dentler also emphasizes a firearm-specific underside and full compatibility on the upper side with BASIS mounting rails, which supports clean installation and system flexibility. In practice, the series appeals to hunters who value a robust steel-based mounting concept, straightforward handling, and the option to configure one rifle for different field roles without changing the underlying mounting standard.

About the Dentler Base rail BASIS - Sako 85 XS

The Dentler Base rail BASIS - Sako 85 XS is a dedicated rifle-side component for users building a modular hunting optics setup on a compatible Sako action. Its role is straightforward but important: it creates the fixed interface on the rifle so that a matching Dentler Mounts Interface upper rail can be attached above. For hunters who alternate between optics or want to standardize several rifles around one mounting concept, that modular structure is the main practical advantage.

This version is made from steel, a material choice that suits a part whose job is to provide a stable foundation between rifle and optic. The result is a mounting base intended for dependable alignment and long-term durability rather than minimum weight alone. The 4.00 mm BH height keeps the base notably low, which helps preserve a close-to-bore optic position once the upper mount is added. That can improve handling, maintain a more natural head position behind the rifle, and avoid an unnecessarily tall overall setup.

The rail’s matte black finish gives it a subdued appearance appropriate for field rifles, while the firearm-specific fit supports clean integration with compatible models including Sako 75 I, Sako 85 XS, Sako L579 Forester, Sako MA 05 XS, and Sako S491. For a hunting rifle that needs a neat, modular, and rifle-specific mounting base, this BASIS rail serves as the foundation of the wider Dentler system.

About Dentler

Dentler Jagdwaffen was founded in 2011 by Daniel Dentler and is based in Leutkirch im Allgäu, Germany. The company focuses on modular riflescope mounting systems for hunting firearms, with its main product families being BASIS and BASIS VARIO. Dentler’s approach centers on separating the rifle-side base rail from the optic-side mounting rail, giving hunters a structured way to configure one firearm for different optics.

The BASIS concept is built around a firearm-specific base rail and an interchangeable optic mounting rail, while BASIS VARIO adds continuous height and windage adjustment. Dentler also offers mounting rails for a wide range of optic interfaces, including formats from Aimpoint, Pulsar, Swarovski, Zeiss, and Weaver/Picatinny. That specialization has made the brand particularly relevant to hunters who want a repeatable, system-based mounting solution rather than a one-piece mount tied to a single optic.
