Dentler Base rail BASIS - Sako 85 M

• Firearm-specific fit: The BASIS base rail is shaped for the Sako 85 M action pattern, which helps the mount sit correctly on the rifle and avoids improvised fitting work.
• Modular BASIS interface: It forms the rifle-side half of the Dentler BASIS system, so one optic rail can be moved between compatible rifles while keeping the mounting concept consistent.
• Steel construction: The rail is made from steel, giving the mounting surface the rigidity needed for repeatable optic positioning and dependable use on hunting rifles.
• Low 4.00 mm build height: The modest BH height of 4.00 mm helps keep the optic close to the bore, supporting a compact setup and a natural cheek weld.
• Matte black finish: The black matte surface keeps reflections down and matches typical hunting optics and rifle finishes for a discreet field setup.

About the BASIS Series

The Dentler BASIS series is a modular mounting system built for hunters and rifle owners who want a structured way to combine one optic with one or more rifles. The concept separates the system into a firearm-specific base rail and an optic-specific mounting rail, creating a standardized interface between rifle and sight. That approach makes the series especially relevant for users who run different daytime optics, red dots or thermal devices and want to keep each optic on its own upper rail.

Within Dentler's lineup, BASIS is the core system for repeatable optic changes without turning the mount into a permanent one-piece solution. The base rail remains on the rifle, while the upper mounting rail remains on the optic. Dentler builds the system around tool steel components, a close mechanical fit and a locking concept intended to hold the optic without play. In practical use, the series suits classic hunting rifles, straight-pull rifles and other sporting firearms where a clean, low-profile mounting platform matters. The defining characteristic of the BASIS family is not a special ring size or rail standard on its own, but the way it creates a common interface across many rifle and optic combinations.

About the Dentler Base rail BASIS - Sako 85 M

The Dentler Base rail BASIS - Sako 85 M is the rifle-side foundation for building a modular optic setup on compatible Sako medium-length actions. It is intended for shooters who want a secure, model-specific base rather than a universal part that may require compromise in fit. Because this rail is matched to the rifle footprint, it provides the correct interface for attaching a Dentler upper mounting rail while keeping the installation compact and mechanically tidy.

Its main advantage is how it supports a practical hunting setup. The 4.00 mm build height helps keep the optic low over the receiver, which can improve head position and preserve balanced rifle handling. The steel construction adds stiffness and durability at the point where recoil forces and repeated optic changes are concentrated. Finished in matte black, the rail integrates cleanly with modern rifles and optics without adding glare.

This model is also relevant for owners of several compatible rifles or optics within the Dentler ecosystem. It works with the Dentler Mounts Interface and is listed for rifles including Sako 75 IV, Sako 85 M, Sako L691, Sako MA 05 M and Sako TRG-S M995. In practice, that makes it a useful base for hunters who want to standardize how optics are mounted across related rifles while keeping the rifle-specific component permanently in place.

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. In Dentler's system concept, the BASIS platform uses a firearm-specific base rail combined with an interchangeable optic mounting rail, giving hunters a consistent interface across different rifles and sighting systems.

Dentler's product range covers rails and mounting solutions for many rifle makes, and its optic-side interfaces are offered for formats such as Aimpoint, Pulsar, Swarovski, Zeiss and Weaver/Picatinny. That specialization has given the brand a clear position in the hunting optics segment: not as a general accessory maker, but as a manufacturer centered on precise, adaptable mounting hardware made in Germany.
