Henneberger Swift Base for Mauser M12

• Quick-detach operation: The HMS Swift system uses a single operating lever, so the optic can be removed or reattached quickly without the slower two-point handling common on traditional mounts.
• Secure locked lever: When closed, the lever is mechanically locked against accidental opening, which helps keep the mount secure during transport, field movement and repeated recoil.
• Adjustable clamping fit: The clamping elements can be adjusted independently, allowing the base to be tuned to the rifle for a firm seat and consistent return to zero after removal and reinstallation.
• Low 7.00 mm build height: The compact profile helps keep the optic close to the bore, which supports a natural cheek weld and a more stable shooting position.
• German-made metal construction: Built in Germany and finished in black, this base is intended for hard field use where repeatability and mechanical durability matter more than unnecessary bulk.

About the Henneberger HMS Swift Series

Henneberger HMS Swift is the company’s quick-detach rifle scope mount series, developed for hunters and sport shooters who want fast handling without giving up a secure mechanical lock-up. The defining feature of the series is its single-lever operation: the optic is attached and released with one movement, which makes scope changes faster and simpler in the field. Once closed, the operating lever is mechanically locked, reducing the chance of accidental release.

The series is built around broad compatibility. Depending on the version, HMS Swift mounts are available for rings and rail-based optics across several tube diameters and rail profiles, and for rifle platforms including Blaser-style interfaces, Picatinny/Weaver rails and selected Sauer, Tikka and Merkel rifles. The design also emphasizes fit and repeatability, with independently adjustable clamping elements that let the mount be set up precisely on the firearm. In construction, Henneberger combines a hard-anodized aluminum body with steel operating parts, hardening the stressed areas to balance low weight with long-term durability.

About the Henneberger Swift Base for Mauser M12

The Henneberger Swift Base for Mauser M12 is a fixed mounting base made for rifles that use the Blaser mounting standard on the upper side while fitting specific actions below, including the Mauser M12 (pre-2019). It serves as the rifle-side foundation for an HMS Swift setup, giving the shooter a stable interface for a quick-detach optic mount while keeping the overall system compact and mechanically straightforward.

Its 7.00 mm build height is an important practical detail. A low base helps keep the sight line closer to the barrel, which usually improves head position behind the optic and supports more consistent mounting of the rifle. That matters on hunting rifles, where a natural cheek weld and fast target acquisition are often more useful than extra clearance. Because the HMS Swift system is designed around one-hand lever operation and adjustable clamping, this base is part of a mounting arrangement intended not only for fast removal, but also for a repeatable fit when the optic is reinstalled.

Compatibility is another key strength. This version is suited to the Mauser M98 Standard, Mauser 98 Action (Without Bulb) and Musgrave K98 in addition to the pre-2019 Mauser M12. For shooters using classic Mauser-pattern rifles or related actions, that makes this base a practical way to build an HMS Swift mounting solution around a familiar rifle platform while retaining the secure lever-locking concept of the series.

About Henneberger

Henneberger was founded by master gunsmith Rudolf Henneberger on November 29, 1966 in Münnerstadt, Germany. The company focuses on gunsmithing, firearm repairs and rifle-scope mounting systems, with a product range that also includes mounting components for red-dot sights. This background is important in the context of scope mounts, because Henneberger’s reputation is rooted in practical mechanical solutions for attaching optics securely and repeatably to sporting and hunting rifles.

The company expanded its capabilities by adding CNC machining in 2000, and Frank Henneberger took over the business on January 1, 2004. Henneberger later moved into a newly built facility in October 2009 and expanded it again in 2017. Based in Münnerstadt, Bavaria, the firm remains closely associated with German-made mounting systems that prioritize precise fit, durable construction and dependable function in regular field use.
