Dentler Base rail BASIS - Steyr Mannlicher Classic L

• Firearm-specific BASIS interface: This base rail is machined for the Steyr Mannlicher Classic L platform, so the fit matches the receiver correctly and avoids improvised mounting solutions that can compromise alignment.
• Modular Dentler system: The rail forms the lower half of the Dentler BASIS mounting concept, allowing one compatible upper mount interface to be exchanged quickly while maintaining a repeatable connection between rifle and optic.
• Steel construction: A steel body gives the rail the rigidity needed for a stable optic platform, helping the mount resist wear from repeated installation and removal in regular hunting use.
• Low-profile build: With a 4.00 mm height, the rail keeps the mounting point close to the rifle, which helps preserve a natural cheek weld and supports a more secure shooting position.
• Matte black finish: The black matte surface keeps reflections down and suits practical field rifles, making the rail visually discreet on hunting setups.

About the BASIS Series

The Dentler BASIS series is the company’s core modular mounting platform for hunting rifles. It is built around a simple idea: a firearm-specific base rail stays on the rifle, while a matching upper mounting rail stays on the optic. This approach gives hunters a structured way to move between different sighting systems without changing the basic interface on the firearm. Within Dentler’s lineup, BASIS sits as the fixed modular solution, while BASIS VARIO adds continuous adjustment functions for users who need additional setup flexibility.

What distinguishes the series is its emphasis on repeatable optic changes, a close mechanical fit to each rifle model, and a robust steel-based design intended for practical field use. BASIS rails are made for a wide range of hunting firearms and support compatible upper interfaces for conventional riflescopes, red dots, and other optic footprints within the Dentler ecosystem. For hunters who use one rifle with several optics, or several rifles with a common mounting standard, the BASIS system offers a clean and organized way to keep equipment consistent.

About the Dentler Base rail BASIS - Steyr Mannlicher Classic L

The Dentler Base rail BASIS - Steyr Mannlicher Classic L is a rifle-specific mounting base made for long-action Steyr platforms including the Steyr SM 12 L, Steyr CL II L, Steyr Mannlicher Classic L, and Steyr Pro Hunter L (After 2003). Its main role is to provide the correct lower interface for the Dentler mounting system, creating a secure starting point for a compatible upper mount.

Because this rail is part of the Dentler BASIS interface, it suits shooters who want a modular hunting setup rather than a one-piece fixed solution. A rifle can remain equipped with its dedicated base, while the optic stays on the corresponding Dentler upper mount. In practice, that makes it easier to configure the rifle for different uses, such as switching between a low-magnification driven-hunt optic and a conventional riflescope, while keeping the mounting standard consistent.

The rail’s steel construction is important in this role because the base is the foundation of the whole optic setup. A rigid base helps the mount resist movement and wear over time, especially when optics are removed and reattached as part of normal use. Its 4.00 mm build height also keeps the interface low over the action, which helps maintain sensible optic positioning and a more natural head position behind the rifle. Finished in black matte, it matches practical hunting rifles without adding glare.

About Dentler

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

This specialization gives Dentler a clear place in the hunting optics market: it is not a general accessories brand, but a manufacturer centered on mounting solutions that let shooters organize multiple rifles and optics within one system. The company’s BASIS VARIO rails add continuous height and windage adjustment, while the standard BASIS system provides the same modular concept in a fixed format. Dentler also supports a broad range of optic interfaces, including formats from Aimpoint, Pulsar, Swarovski, Zeiss, and Weaver/Picatinny.
