Dentler Base rail BASIS - Steyr Mannlicher S, M

• Firearm-specific BASIS interface: This base rail is shaped for Steyr Mannlicher S and M pattern actions, so the mount sits correctly on the rifle and provides a secure foundation for repeatable optic installation.
• Modular Dentler system: As part of the BASIS platform, the rail works with the Dentler Mounts Interface, making it practical to move different optics within the same mounting system instead of building a separate setup for every rifle.
• Steel construction: The steel body gives the rail the rigidity needed for a stable optic connection, which helps maintain alignment under regular field use and repeated mounting cycles.
• Low 4.00 mm build height: The compact profile keeps the optic close to the bore, supporting a tidy rifle setup and a more natural head position behind the scope.
• Matte black finish: The non-reflective surface suits hunting rifles and reduces visual distraction, while also matching common scope and rifle finishes.

About the BASIS Series

Dentler BASIS is the company’s modular mounting system for hunters who want a firearm-specific base rail on the rifle and an interchangeable optic mounting rail on the sight. Within the Dentler lineup, BASIS sits alongside BASIS VARIO, but it focuses on a straightforward fixed-base concept that keeps the rifle ready for repeatable optic changes inside the same system. The idea is practical: the base remains on the firearm, while the optic stays on its matching upper mount, so changing configurations is simpler and more consistent.

The series is built around steel base rails, precise fit to the individual firearm model, and full compatibility with Dentler BASIS mounting rails. That makes it relevant for classic hunting rifles, modern stalking setups, and owners who use more than one optic for different conditions. Compared with one-piece non-modular solutions, the BASIS family is designed around flexibility without abandoning a solid mechanical interface. For users who want a clean, low-profile rifle setup and the option to standardize optics across several firearms, the BASIS series offers a structured mounting platform with a clear emphasis on repeatability, compatibility, and practical field handling.

About the Dentler Base rail BASIS - Steyr Mannlicher S, M

The Dentler Base rail BASIS - Steyr Mannlicher S, M is a rifle-specific mounting base made for Steyr Mannlicher platforms in the S and M pattern, including compatible SM 12, CL II, Classic, and Pro Hunter variants. Its main role is to create the lower half of the Dentler modular mounting system, giving the rifle a permanent and correctly fitted interface for a compatible upper mounting rail. For hunters who use one rifle with different optics, or who want a clean way to standardize their setup, that modular approach is the real advantage of this model.

The rail uses a steel construction and a 4.00 mm BH height, which helps keep the assembly compact and mechanically stable. A lower mounting height generally supports a more natural cheek weld and keeps the optic closer to the bore line, both of which matter when building a practical hunting rifle. The matte black finish also suits field use by keeping the appearance subdued and consistent with common rifle and scope finishes.

Because this base is designed specifically for the listed Steyr Mannlicher rifles, it is not a generic rail that depends on compromise fitting. That model-specific geometry is important in practice: it supports proper contact with the action and gives the Dentler Mounts Interface the stable foundation it needs. For a hunting optics setup built around repeatable mounting, compact height, and compatibility with the wider Dentler BASIS system, this rail serves as the essential starting point.

About Dentler

Dentler Jagdwaffen was founded in 2011 by Daniel Dentler. Based in Leutkirch im Allgäu, Germany, the company focuses on modular riflescope mounting systems for hunting firearms. Its best-known platforms are BASIS and BASIS VARIO, both built around the idea of separating the rifle-specific base from the optic-specific upper mount.

That system approach defines Dentler’s place in this product category. The standard BASIS system uses a firearm-specific base rail with 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 Aimpoint, Pulsar, Swarovski, Zeiss, and Weaver/Picatinny formats. This specialization gives the brand a clear reputation among hunters who want a structured, repeatable way to configure optics across different rifles.
