Dentler Base rail BASIS VARIO - Steyr Mannlicher Classic L

• Continuously adjustable alignment: The BASIS VARIO base rail allows stepless windage and height correction at the mount, so the rifle can be matched to the optic without using up the scope’s internal adjustment range.
• Modular Dentler interface: This base works with the Dentler Mounts Interface, making it easier to move a compatible optic setup between rifles while keeping the mounting concept consistent.
• Steel construction: The steel body gives the rail the rigidity needed for a secure optic platform and dependable return to position under repeated recoil and field use.
• Rifle-specific fit: Designed for Steyr Mannlicher Classic L-pattern actions, the rail matches the receiver geometry correctly, which supports precise installation and stable optic alignment.
• Low 4.00 mm build height: The compact profile helps keep the optic mounted close to the bore, supporting a natural shooting position and a more balanced rifle setup.

About the BASIS VARIO Series

Dentler BASIS VARIO sits at the more adaptable end of the company’s modular mounting range. While the standard BASIS system is built around a firearm-specific base and an interchangeable upper mounting rail, BASIS VARIO adds continuous windage and height adjustment directly in the base rail. In practical terms, that makes it especially useful for hunters and rifle owners who want to pair one optic with more than one firearm while preserving the optic’s own adjustment reserve.

The series is aimed at users who value a repeatable mounting concept but also need correction at the interface between rifle and optic. That is particularly relevant when setting up hunting optics on different rifles or when fine-tuning alignment without relying entirely on the scope’s turrets. Made in Germany and built around a modular two-part concept, BASIS VARIO combines a rifle-specific lower rail with a compatible Dentler upper mount. The result is a system focused on secure fit, mechanical consistency and practical flexibility for modern hunting rifle setups.

About the Dentler Base rail BASIS VARIO - Steyr Mannlicher Classic L

The Dentler Base rail BASIS VARIO - Steyr Mannlicher Classic L is a rifle-specific mounting foundation 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 role is not simply to provide an attachment point, but to create a stable and adjustable interface between the rifle and a compatible Dentler upper mount.

What sets this model apart is the BASIS VARIO adjustment concept. Because windage and height can be corrected at the base, the optic can remain closer to its optical center instead of using a large portion of its internal adjustment travel during zeroing. In practice, that can be valuable when building a precise hunting rifle setup, especially if the same optic assembly may later be used on another compatible rifle within the Dentler system.

The rail is made from steel, which suits the job of carrying an optic under recoil while maintaining a firm interface over time. Its 4.00 mm BH height keeps the base relatively low, helping maintain a sensible sight line and avoiding unnecessary bulk. Finished in matte black, it matches the restrained look expected on a hunting rifle while reducing visual distraction. For shooters using the Dentler modular ecosystem, this base rail is the rifle-specific starting point that combines fit, strength and adjustment flexibility in one component.

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 best-known platforms being BASIS and BASIS VARIO. Dentler’s approach centers on separating the rifle-specific base from the optic-specific upper rail, creating a flexible system for hunters who use different optics or more than one rifle.

The BASIS concept uses a dedicated base rail on the firearm and an interchangeable optic mounting rail above it, while BASIS VARIO adds continuous height and windage adjustment at the base. Dentler also offers mounting rails for a wide range of optic footprints, including formats from Aimpoint, Pulsar, Swarovski, Zeiss and Weaver/Picatinny. That specialization has made the brand particularly relevant to hunters who want a consistent mounting standard across different rifles and sighting systems.
