Dentler Base rail BASIS - Sako S20 Product description

  • Firearm-Specific Fit: This BASIS base rail is shaped for the Sako S20, so it mates cleanly to the rifle and avoids improvised fitting work during installation.
  • Modular Dentler Interface: The rail forms the rifle-side part of the Dentler BASIS system, allowing one compatible optic mounting rail to be moved between suitable rifles with a consistent interface.
  • Steel Construction: A steel body gives the base the rigidity needed for a secure optic platform and dependable alignment under regular field use.
  • Repeatable Reattachment: Dentler’s BASIS concept is built around a play-free lock-up, which helps maintain mounting consistency when an optic is removed and reattached.
  • Matte Black Finish: The black matte surface keeps the rail visually discreet on a hunting rifle and matches modern optic and rifle finishes well.

About the Dentler Steel Mounts Series

Dentler Steel Mounts are the steel-bodied options within the company’s BASIS riflescope mounting system, developed for hunters who want a modular way to combine rifles and optics without giving up a solid mechanical connection. The system is built around two separate parts: a firearm-specific base rail that stays on the rifle and an optic-specific mounting rail that stays on the sight. This layout makes the series especially useful for shooters who run different optics or want to move one optic assembly between compatible rifles.

A defining characteristic of the series is its play-free locking concept, using steel crossbars and a locking pin to secure the mounting rail onto the base. In practice, that matters because repeatable removal and reattachment are only useful when the interface returns to the same position reliably. Dentler also keeps the platform broad in application, with BASIS mounting rails available for ring mounts, Weaver/Picatinny interfaces and several manufacturer-specific optic footprints. Within the Dentler lineup, the steel variants suit users who prioritize robustness and a traditional all-steel mounting structure for hunting optics.

About the Dentler Base rail BASIS - Sako S20

The Dentler Base rail BASIS - Sako S20 is the rifle-side foundation for building a modular optic setup on the Sako S20. Rather than acting as a universal adapter, it is made for this specific rifle platform, which is important for secure seating and straightforward installation. For hunters and practical rifle users, that rifle-specific geometry helps create a stable starting point before the optic mounting rail is added.

As part of the Dentler BASIS system, this base rail is intended to work with the Dentler Mounts Interface above it. The practical advantage is flexibility: the base remains on the rifle, while the optic can stay attached to a compatible Dentler mounting rail. That makes the setup useful for shooters who alternate between different sighting systems or who want a cleaner way to share an optic assembly across compatible rifles in the same system.

The all-steel construction supports the role of the base as a structural component rather than a simple accessory. A base rail has to resist movement, preserve alignment and provide a dependable clamping surface, and steel is well suited to that task. The matte black finish keeps the rail understated on the rifle and fits naturally with modern hunting optics and chassis-style rifle designs such as the S20. Overall, this model is best understood as a precise interface part: simple in form, but central to a repeatable and modular mounting setup.

About Dentler

Dentler is a German specialist in modular riflescope mounting systems, founded in 2011 by Daniel Dentler. The company is based in Leutkirch im Allgäu, Germany, and focuses on mounting solutions for hunting firearms rather than on general shooting accessories. Its best-known systems are BASIS and BASIS VARIO, both built around the idea of separating the rifle-side base from the optic-side mounting rail.

That modular approach defines Dentler’s place in the optics-mount market. The company offers firearm-specific base rails and matching optic interfaces for a wide range of rifles and sight formats, including Aimpoint, Pulsar, Swarovski, Zeiss and Weaver/Picatinny patterns. For hunters, Dentler is known for mounts that emphasize repeatable optic changes, model-specific fit and a system architecture that can be expanded as rifles or optics change over time.

Good morning, is the Dentler FMGS-00940 base compatible with the Sako 90 in 300 Win. Mag.? Thanks.

Buongiorno la base dentler FMGS-00940 è compatibile con sako 90 in calibro 300 win.mag.? grazie

by Giuseppe

Dear Sir,

We need a bit more information about your Sako 90 rifle: does it have the standard Sako Optilock interface — or does it already use a Picatinny rail?
If you have a Picatinny rail, then the Dentler Base Rail BASIS (SKU: FMGS-00940) will fit.
If not, please check out suitable alternative mounts here: https://www.optics-trade.eu/en/mounts/shopby/compatibility_below-sako_90_l_optilock.html

Thank you for your understanding.
