Henneberger HMS Swift Mount for Sauer 303, 40 mm

• Single-lever quick detach: The Henneberger HMS Swift locks and releases with one operating lever, so the scope can be removed or reinstalled quickly without fumbling with separate clamps.
• Repeatable return to zero: Independently adjustable clamping elements help the mount seat consistently on the Sauer 303 interface, supporting reliable repeatability when switching optics or transporting the rifle.
• 40 mm ring configuration: This version is built for 40 mm scope tubes, giving a direct, purpose-made fit for larger premium optics without adapters.
• Hard-anodized aluminum body: The aluminum construction keeps weight down, while hardened steel operating parts handle the stress points that matter in repeated field use.
• Secure locked lever: The closed lever is mechanically locked against accidental opening, which adds confidence when carrying the rifle through brush, vehicles, or rough terrain.

About the Henneberger HMS Swift Series

Henneberger HMS Swift is the company’s quick-detach scope mount series, developed for hunters and sport shooters who want fast handling without giving up a stable, repeatable connection between rifle and optic. The series covers a wide range of rifle platforms, including versions for Sauer 303, Sauer 404, Tikka T3, Merkel KR1, B3 and B4, as well as Picatinny and Weaver-based applications. That broad compatibility makes HMS Swift a practical family for shooters who prefer the same operating concept across different rifles.

A defining feature of the series is its single-lever attachment system. Instead of working with two separate locking points, the mount is attached and released with one lever, which speeds up optic changes and simplifies handling in the field. The clamping elements are independently adjustable, allowing the fit to be tuned to the rifle for secure seating and repeatable positioning. Henneberger builds the main body from hard-anodized aluminum, while the operating parts are made from steel and hardened in stressed areas. The series is offered with different optic interfaces, including ring mounts and rail-based versions, so it suits both traditional hunting scopes and other sighting systems.

About the Henneberger HMS Swift Mount for Sauer 303, 40 mm

The Henneberger HMS Swift Mount for Sauer 303, 40 mm is a dedicated detachable mount for rifles using the Sauer 303 (ISI) interface and scopes with a 40 mm tube. It is designed for shooters who want the speed of a quick-detach system but still expect the mount to return to the same position after removal and reinstallation. That makes it especially useful for hunting rifles that may alternate between day optics, transport configurations, or different sighting setups.

The practical advantage of this model lies in the one-hand operating lever. A single movement locks or unlocks the mount, so the optic can be removed quickly when needed and put back on without the slower routine of working multiple fasteners. Henneberger also uses independently adjustable clamping elements, which help the mount sit correctly on the rifle’s rail and maintain the consistent engagement needed for repeatable performance. The lever is mechanically locked in the closed position, reducing the chance of accidental release while the rifle is carried in the field.

Its construction matches that intended use. The mount body is made from aluminium in a black finish to keep overall weight manageable, while the stressed operating parts are designed for repeated use. With a 14.50 mm ring height, 34.50 mm overall height and 0 MOA inclination, this version is configured as a straightforward, neutral mounting solution for a 40 mm scope on the Sauer platform.

About Henneberger

Henneberger was founded by master gunsmith Rudolf Henneberger on November 29, 1966, in Münnerstadt, Germany. The company built its reputation in gunsmithing, firearm repair and scope-mounting systems, with a product range that includes mounting components as well as mounts for riflescopes and red-dot sights. This background is directly relevant to products such as the HMS Swift, where precise fit and repeatable alignment matter as much as simple attachment.

The company expanded its capabilities by adding CNC machining in 2000, and Frank Henneberger took over the business on January 1, 2004. Henneberger moved into a newly built facility in October 2009 and expanded it again in 2017. Based in Münnerstadt, Bavaria, the company remains focused on practical mounting solutions for sporting and hunting firearms.
