Dentler Dural Single Ring, 40 mm

• 40 mm ring interface: Built for optics with a 40 mm tube or body diameter, this single ring provides the correct fit for large-format sighting systems while keeping the mounting setup consistent across the Dentler platform.
• Aluminum Dural construction: The ring is made from aluminum, which keeps weight down without giving up the rigidity needed for a stable optic mounting point on a hunting rifle.
• Modular BASIS compatibility: As part of the Dentler BASIS ecosystem, the ring can be combined with compatible upper rails, making it easier to configure a mount around a specific optic rather than replacing the whole system.
• Ø 8 mm interface support: Compatibility with Dentler, Henneberger, MAK, Kozap, Mauser and Recknagel Ø 8 mm interfaces gives this ring practical value when adapting an existing setup or replacing a damaged upper component.
• KR 0.0 mm extension: The 0.0 mm extension keeps the ring in a neutral position, which is useful when the optic already sits correctly on the rail and no additional offset is needed.

About the Dentler Dural Rings Series

Dentler Dural Rings are individual ring components developed for the Dentler BASIS mounting system. The series is intended for shooters and hunters who use ring-mounted optics and want the flexibility of a modular mount rather than a fixed one-piece solution. Instead of treating the mount as a single-purpose part, Dentler builds the system around interchangeable components, so the upper assembly can be matched to the optic while remaining compatible with the broader BASIS platform.

A defining feature of the series is its role within the BASIS and BASIS VARIO ecosystem. Dentler offers ring-compatible mounting rails for both systems, allowing the same general mounting concept to serve conventional hunting rifles as well as more adjustable setups. The BASIS design is known for its repeatable, play-free locking interface, which matters when an optic is removed and reinstalled and the user expects the setup to return to the same position. The Dural Rings themselves are made from aluminum and are offered for several common tube diameters, including 25.4 mm, 30 mm, 34 mm, 36 mm and 40 mm, making the series relevant for everything from standard riflescopes to larger specialty optics.

About the Dentler Dural Single Ring, 40 mm

The Dentler Dural Single Ring, 40 mm is a modular upper mounting component for optics that require a 40 mm ring interface. In practical terms, it is aimed at users who need to build or replace part of a Dentler ring-based mount without changing the rest of the system. That makes it especially useful in hunting optics setups where an existing BASIS or BASIS VARIO rail is already in service and only the ring size or ring component needs to match a different optic.

The ring is made from aluminum, which helps keep the complete mount lighter than an all-steel solution. On a field rifle, that matters because unnecessary weight at the top of the receiver affects balance and handling, especially when the optic itself is already large. The black matte finish also suits practical hunting use by reducing visual distraction and blending with common riflescope and rail finishes.

Its KR 0.0 mm extension indicates a neutral geometry, so this version is intended for setups that do not need additional forward or rearward offset at the ring position. Compatibility with Dentler, Henneberger, MAK, Kozap, Mauser and Recknagel Ø 8 mm interfaces broadens its usefulness when integrating with established mounting hardware. As a single ring rather than a complete mount, it is best understood as a precise spare or configuration part within a modular riflescope mounting system, where correct diameter, interface fit and consistent positioning matter more than unnecessary complexity.

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. This specialization gives Dentler a clear place in the hunting optics market: it is not a general accessories brand, but a manufacturer centered on how optics are mounted, exchanged and aligned on sporting rifles.

The BASIS concept uses a firearm-specific base rail together 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 formats, including Aimpoint, Pulsar, Swarovski, Zeiss and Weaver/Picatinny. That system-based approach has made the brand particularly relevant to hunters who want repeatable optic changes and a more adaptable mounting setup across different rifles and sighting devices.
