Dentler Base rail BASIS - Mauser M98 / K98 (without bulb, without holes)

• Modular BASIS interface: This base rail forms the firearm-specific foundation of the Dentler mounting system, making it possible to swap compatible optic rails while keeping a precise, repeatable connection between rifle and sight.
• Low 4.00 mm build height: The slim profile helps keep the optic close to the bore, which supports a natural cheek weld and a more balanced rifle setup for hunting use.
• Steel construction: A steel base gives the mounting platform the rigidity needed for secure optic support and dependable alignment under regular field use.
• Firearm-specific fit: Designed for Mauser M98 and K98-pattern actions without bulb and without holes, the rail matches the receiver geometry so installation starts from a platform made for this action type.
• Matte black finish: The non-reflective surface suits practical hunting rifles, reducing glare and giving the mount a discreet appearance that matches modern optics and metalwork.

About the BASIS Series

Dentler BASIS is the company’s core modular riflescope mounting system, developed for hunters who want one optic platform that can be configured around different rifles and sighting solutions. The concept separates the mount into two parts: a firearm-specific base rail that stays on the rifle and an interchangeable upper mounting rail that stays with the optic. This approach gives the system its practical appeal, because it simplifies moving between different optic formats while preserving a consistent mechanical interface.

Within Dentler’s lineup, BASIS sits as the straightforward fixed-base solution, while BASIS VARIO adds continuous height and windage adjustment. The standard BASIS family focuses on a secure, repeatable connection, broad compatibility with hunting rifles, and support for a wide range of optic interfaces, including ring mounts, red dot footprints, and rail-based scope formats. A defining characteristic of the series is its emphasis on repeatable optic changes and a stress-free fit, which matters to shooters who remove optics for transport, switch between day optics and other sighting systems, or maintain more than one upper assembly for the same rifle.

About the Dentler Base rail BASIS - Mauser M98 / K98 (without bulb, without holes)

This version of the Dentler Base rail BASIS is built specifically for the Mauser M98 / K98 platform in the stated configuration without bulb, without holes. Its role is simple but important: it creates the lower interface that allows a compatible Dentler upper mount to lock onto the rifle in a consistent and controlled way. For owners of classic Mauser-pattern actions, that matters because the mount must match the receiver form correctly before any optic can perform as intended.

The rail’s 4.00 mm height helps keep the setup compact, which is useful when building a practical hunting rifle with sensible sight height and stable head position behind the optic. Its steel construction supports the kind of rigidity expected from a mounting base, helping the optic system remain stable during normal use, transport, and repeated mounting cycles. The matte black finish keeps the appearance subdued and appropriate for traditional as well as modern rifle builds.

As part of the Dentler ecosystem, this base is intended to work with the Dentler Mounts Interface on the upper side. That makes it a sensible choice for shooters who want to use the BASIS system’s modular logic on a Mauser action: keep the base on the rifle, keep the optic on its matching upper rail, and build the rifle around a mounting standard designed for repeatable installation and practical field handling.

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 product families being BASIS and BASIS VARIO. The BASIS concept pairs a firearm-specific base rail with an interchangeable optic mounting rail, while BASIS VARIO adds continuous height and windage adjustment for more flexible setup work.

Dentler’s specialization is clear in the breadth of its compatibility program. The company offers base rails for rifles from makers such as Benelli, Browning, Merkel, Heckler & Koch, and Rößler, and its mounting rails are available for optics and interfaces including Aimpoint, Pulsar, Swarovski, Zeiss, and Weaver/Picatinny formats. That concentration on modularity and cross-platform fit has made Dentler a recognized name for hunters who want a structured, system-based approach to mounting optics.
