Henneberger Swift Base for Mauser K98

• Low 7.00 mm build height: Keeps the optic close to the bore for a natural cheek weld and a more direct sight picture, which is especially useful on classic Mauser-pattern rifles.
• HMS Swift quick-detach interface: The base is part of Henneberger’s single-lever Swift system, allowing fast removal and reattachment of the optic without turning the rifle into a slow, tool-dependent setup.
• Mechanical lever lock: The closed operating lever is locked against accidental opening, so the mount stays secure during transport, field carry and repeated recoil.
• Independently adjustable clamping elements: Fine adjustment helps the mount seat correctly on the rifle, supporting repeatable positioning and dependable return to zero after removal.
• German-made steel-and-aluminum design: The Swift system combines a hard-anodized aluminum body with steel operating parts in stressed areas, balancing low weight with the durability expected from a hunting or sporting rifle mount.

About the Henneberger HMS Swift Series

Henneberger HMS Swift is the company’s quick-detach scope-mount series, developed for shooters who want a fast, repeatable way to move optics on and off the rifle without adding unnecessary complexity. The defining feature of the series is its single-lever operation: one movement locks or releases the mount, which makes the system practical for hunters changing optics in the field and for sport shooters who value fast handling at the bench or on the range.

The series covers a wide range of rifle and optic interfaces, including versions for Blaser-style mounting points, Picatinny and Weaver rails, and several rifle-specific platforms. It is also offered with different upper interfaces such as rings and rail-compatible tops for common scope and sight formats. Across the range, Henneberger uses a design with independently adjustable clamping elements so the mount can be fitted precisely to the firearm. The mount body is made from hard-anodized aluminum, while the operating parts are steel with hardened stressed areas. In practice, that gives the Swift series its characteristic mix of quick handling, secure lock-up and repeatable positioning for hunting optics and sporting rifles.

About the Henneberger Swift Base for Mauser K98

The Henneberger Swift Base for Mauser K98 is a rifle-specific mounting base made for shooters who want to fit a Blaser mounting standard optic interface to a Mauser-pattern action without giving up a low, practical setup. Its compatibility with the Mauser M98 Standard, Mauser 98 Action (Without Bulb), Musgrave K98 and pre-2019 Mauser M12 variants makes it particularly relevant for traditional hunting rifles and classic sporting conversions built around the 98 system.

The key advantage of this base is how it brings the HMS Swift concept to the Mauser platform. Combined with the Swift upper, it supports fast optic attachment and removal through a single lever, while the mechanical lock helps prevent unintended release. That matters for users who alternate between different sighting systems or need to remove an optic for transport and reinstall it with confidence in repeatable positioning. The 7.00 mm height keeps the mounting line low, which helps preserve a stable cheek position and avoids the top-heavy feel that taller adapters can introduce.

Finished in black and made in Germany, this base is aimed at practical use rather than ornament. It gives the Mauser K98 family access to a modern quick-detach mounting layout while retaining the secure fit and straightforward handling expected on a working rifle. For hunting optics or general sporting use, that combination of low profile, platform-specific fit and Swift-system compatibility is what defines this model.

About Henneberger

Henneberger was founded by master gunsmith Rudolf Henneberger on November 29, 1966, in Münnerstadt, Germany. Based in Münnerstadt, Bavaria, the company built its reputation in gunsmithing, firearm repair and, in particular, rifle-scope mounting systems. That background is directly relevant to products such as the Swift base, where precise fit and repeatable alignment matter as much as the material itself.

Over time, Henneberger expanded from workshop-based gunsmithing into a broader manufacturing role, adding CNC machining in 2000 and later moving into a newly built facility in 2009, which was expanded again in 2017. Frank Henneberger took over the business on January 1, 2004. Today, the company’s range includes scope-mount components and mounts for red-dot sights, with a strong focus on practical, mechanically sound solutions for hunting and sporting firearms.
