Henneberger Single Ring for Pivot and HMS SAMO Mount, 40 mm

• 40 mm ring format: Built for optics with a 40 mm tube diameter, this upper ring provides the correct interface for large-tube riflescopes while keeping the mounting system properly matched to the optic.
• Steel construction: The ring is made from steel, which gives the assembly the rigidity needed to hold zero under recoil and maintain consistent alignment over repeated use.
• Compatible with pivot and HMS SAMO mounts: Designed as a single ring for Pivot and HMS SAMO systems, it is a practical replacement or spare part when maintaining an existing Henneberger mounting setup.
• Made in Germany: German manufacture reflects Henneberger’s focus on precise machining and dependable fit, which matters when a ring must clamp the scope tube evenly and return to the same position in service.
• Black finish: The black surface gives the ring a subdued appearance that matches most hunting optics and mounting components while helping the part blend into the rifle setup.

About the Henneberger HMS Samo Series

Henneberger HMS SAMO is a detachable mount series developed for rifles with a Blaser saddle mount interface. Within Henneberger’s lineup, it serves shooters who want a mounting solution that can be removed and reattached without giving up the repeatability expected from a serious hunting or sporting rifle setup. The series is described as recoil-resistant and repeatable after removal and reattachment, which makes it well suited to rifles that may carry different optics for different roles.

The HMS SAMO family covers both riflescope ring versions and interfaces for red-dot sights and rails, so it is not limited to one optic type. Ring variants are offered for 25.4 mm, 26 mm, 30 mm, 34 mm, 36 mm, and 40 mm tubes, while other versions support rail-mounted optics and compact reflex sights. A defining characteristic of the series is its solid steel construction, with the mounts milled from solid material for strength and consistent fit. In practice, that gives the HMS SAMO range a straightforward mechanical design: robust, repeatable, and intended for shooters who value secure attachment and dependable return to zero.

About the Henneberger Single Ring for Pivot and HMS SAMO Mount, 40 mm

The Henneberger Single Ring for Pivot and HMS SAMO Mount, 40 mm is a replacement or spare upper mounting component for shooters using a compatible Henneberger pivot or HMS SAMO setup with a 40 mm scope tube. Its role is simple but important: it forms the correct clamping interface between the mount and the riflescope, so the optic sits securely and remains properly aligned in the mounting system.

The use of steel construction is especially relevant in a ring component, because rigidity at the ring level helps the complete mount resist movement under recoil and maintain even support around the scope tube. That matters not only for holding zero, but also for protecting the optic from uneven clamping pressure when the system is assembled correctly. The black finish keeps the part visually discreet and consistent with most riflescope and mount combinations.

As part of the Henneberger HMS Samo family, this ring is intended for users who already rely on a detachable mounting system and want to keep that setup serviceable over time. It is particularly useful as a matching spare when replacing a damaged ring, rebuilding an existing mount, or configuring a compatible upper assembly for a large-tube optic. With KR 0.0 mm extension and a design made specifically for Henneberger’s pivot and HMS SAMO platform, it is a purpose-built component rather than a generic ring, which is exactly what matters when fit and repeatability are priorities.

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 repairs, and especially in riflescope mounting systems, which remain central to its product range. Alongside complete mounts, Henneberger also produces scope-mount components and mounting solutions for red-dot sights.

The company expanded its technical capabilities by adding CNC machining in 2000, a step that fits naturally with the precision required for mounting parts and interfaces. Frank Henneberger took over on January 1, 2004, and the business later moved to a newly built facility in October 2009, with a further expansion in 2017. Based in Münnerstadt, Bavaria, Henneberger is known for practical, mechanically focused mounting solutions made for reliable fit, repeatability, and long service life.
