EAW Rear Pivot Ring, 40 mm

• 40 mm Ring Size: Built for riflescopes with a 40 mm tube, this rear pivot ring provides the correct fit for secure clamping and consistent alignment within an EAW pivot-mount setup.
• Steel Construction: The steel body gives this mount part the rigidity needed to hold zero under recoil and repeated use, making it well suited to durable hunting optics installations.
• Rear Pivot-Mount Component: As the rear ring in an EAW pivot system, it supports the repeatable on-and-off function that makes pivot mounts practical when a rifle must alternate between scoped and open-sight use.
• Made in Germany: German manufacture reflects EAW’s focus on precise fit and dependable machining, which matters in mounting systems where small tolerances affect repeatability and long-term stability.
• Black Finish: The black finish gives the part a discreet appearance and matches the look of most riflescopes, bases and hunting rifles.

About the EAW Spare Parts Series

EAW Spare Parts supports the company’s professional mount range with original replacement components and practical workshop tools. Rather than treating mounts as sealed, disposable assemblies, EAW structures this series around the idea that a quality mounting system should remain serviceable over time. The range covers parts for pivot mounts, slide-on or roll-off mounts, and claw mounts, alongside fitting aids intended to simplify installation and maintenance.

Within the series, EAW includes items such as ring-clamping screws, fastening screws for shaped rings, and specialized tools for tasks like polishing the slewing ring on a pivot mount’s front foot. The lineup also includes mounting and alignment aids that help protect the riflescope during fitting and support correct positioning. In practice, the EAW Spare Parts series is aimed at shooters, gunsmiths and professional installers who want to maintain the original function of an EAW mount, preserve repeatability, and replace worn or application-specific components with parts designed around the same modular mounting system.

About the EAW Rear Pivot Ring, 40 mm

The EAW Rear Pivot Ring, 40 mm is a dedicated rear mount component for EAW pivot-mount systems, intended for riflescopes with a 40 mm tube. In a pivot mount, the rear ring is more than a simple clamp: it forms part of the locking and return-to-zero relationship between the optic and the rifle. That makes precise fit especially important, because the rear section contributes directly to how securely the scope sits and how consistently it returns to the same position after removal and reinstallation.

This version uses a steel construction, which suits the demands placed on a recoil-bearing mount part. Steel helps the ring resist deformation, maintain clamping integrity and support long-term repeatability in the field. For hunting rifles and traditional sporting builds that use an EAW pivot base, that matters not only for zero retention but also for confidence when the optic is detached for transport, storage or use of iron sights and then fitted again.

The ring’s black finish keeps the appearance understated and visually compatible with most riflescopes and base sets. As an original EAW spare part, it is intended for proper integration with EAW Type Pivot Bases, making it a practical choice when replacing a worn component, rebuilding an existing mount, or configuring a pivot setup around a 40 mm scope tube.

About EAW

Ernst Apel founded the company in Würzburg, Germany, in 1919. In 1923, he acquired Elektro-Dental-Werke Frankfurt and changed the EDW brand to EAW, meaning Ernst Apel Würzburg. The company developed and produced its first riflescope mounts in 1945, and since 1951 mount development and production have been its primary focus.

Today, EAW is known for German-made mounting solutions for sporting and professional firearms, including pivot, slide-on or roll-off, and claw mounts. The company later moved production from Würzburg to Gerbrunn in 1970, and Ernst Apel GmbH is now headquartered in Eibelstadt, Germany. Alongside mounts, EAW also offers thermal imaging cameras, but its reputation in this category rests on long experience in precise, repeatable riflescope mounting systems.
