Dentler Base rail BASIS - Steyr Mannlicher SM12 WSM

• Modular BASIS interface: This base rail forms the firearm-specific foundation of the Dentler BASIS system, allowing a compatible optic mounting rail to be fitted and removed in a repeatable way.
• Steel construction: The steel body gives the rail the rigidity needed for a secure optic platform, helping the mount stay stable under recoil and regular field use.
• Low 4.00 mm build height: A low-profile design keeps the optic close to the bore, which supports a natural shooting position and helps preserve practical rifle handling.
• Rifle-specific fit: Made for the Steyr Mannlicher SM12 WSM, the rail is matched to the action so installation is straightforward and the interface sits correctly on the rifle.
• Made in Germany: German manufacture reflects Dentler’s focus on precise machining and consistent tolerances, which matters in a mounting system built around repeatable alignment.

About the BASIS Series

Dentler BASIS is the company’s modular mounting platform for hunters who want to use one optic setup across different rifles or switch between optics without changing the underlying system. At the core of the series is a firearm-specific base rail that remains on the rifle, paired with an interchangeable optic mounting rail that stays on the scope or sight. This approach separates the rifle interface from the optic interface, making the system flexible without turning it into a universal one-size-fits-all mount.

Within Dentler’s lineup, BASIS sits as the standard modular solution, while BASIS VARIO adds continuous height and windage adjustment. The standard BASIS concept focuses on a solid, repeatable connection, straightforward handling, and compatibility across a wide range of hunting optics and firearm models. The rails are built with field use in mind, using robust materials and a mechanical design intended to keep the optic platform stable while still allowing practical interchangeability. For hunters who value a clean, rifle-specific mounting solution rather than improvised adapters, the BASIS series is designed to provide a consistent foundation for day optics, red dots, and other sighting systems.

About the Dentler Base rail BASIS - Steyr Mannlicher SM12 WSM

The Dentler Base rail BASIS - Steyr Mannlicher SM12 WSM is the rifle-side component of the Dentler modular mounting system, made specifically for the Steyr Mannlicher SM12 WSM. Its job is not simply to hold an optic, but to create the precise interface that allows a compatible Dentler mounting rail to lock onto the rifle in a consistent and practical way. For hunters who use different optics for different conditions, that matters because the base rail becomes the fixed reference point on the firearm.

Its steel construction gives the rail the stiffness expected from a serious mounting component, which is important for maintaining a secure connection under recoil and during repeated mounting cycles. The 4.00 mm BH height. keeps the setup low, helping the optic sit closer to the bore line for a more natural cheek weld and less bulk above the receiver. That low profile also helps preserve the handling characteristics of the rifle rather than making it feel top-heavy.

Because this rail is made for a specific Steyr Mannlicher platform, fit is more purposeful than with generic rails or adapter-based solutions. In practice, that means a cleaner installation, proper contact with the rifle, and compatibility with the broader Dentler Mounts Interface. For a hunting rifle that may be used with more than one sighting setup, this base rail provides the stable starting point that makes the modular system useful in the field.

About Dentler

Dentler Jagdwaffen was founded in 2011 by Daniel Dentler. The company specializes in modular riflescope mounting systems for hunting firearms, with its best-known product families being BASIS and BASIS VARIO. The BASIS concept combines a firearm-specific base rail with an interchangeable optic mounting rail, while BASIS VARIO adds continuous height and windage adjustment for more flexible setup tuning.

Based in Leutkirch im Allgäu, Germany, Dentler focuses on mounting solutions rather than general optics production. Its rails are offered for a broad range of hunting rifles and for optics interfaces including Aimpoint, Pulsar, Swarovski, Zeiss, and Weaver/Picatinny formats. That specialization has given the brand a clear place in the hunting optics market: practical, system-based mounts built around repeatable fit and cross-platform compatibility.
