About the EAW Pivot Mounts Series

EAW Pivot Mounts are one of the company’s best-known mounting systems and have been part of the brand’s range for more than 50 years. The series is designed for common rifles and long guns, with the core idea of combining a secure mechanical lock-up with the ability to remove and reinstall an optic without changing the point of impact. That makes the system especially relevant for hunting rifles and traditional sporting firearms where a detachable scope mount is valued for transport, maintenance, or switching between sighting solutions.

A defining characteristic of the series is its adjustable front and rear mount-foot fit, which helps the mount interface precisely with the rifle and optic assembly. EAW also presents the pivot mount as suitable for use with a second scope or aiming device, which is one of the practical reasons this design remains popular. Within the broader EAW lineup, the pivot series represents a classic detachable mounting solution focused on repeatability, mechanical stability, and compatibility across many rifle models.

About the EAW Rear Base for Pivot Mount, Tikka 658

The EAW Rear Base for Pivot Mount, Tikka 658 is the rifle-specific rear mounting component for building an EAW pivot mount on the Tikka 658 platform. In a pivot-mount system, the rear base is a critical part of the lock-up geometry: it provides the rear contact point that helps the mount return to the same position each time the optic is attached. In practical terms, that matters for shooters who remove a riflescope between outings, travel with the rifle in a more compact case, or keep more than one sighting setup for different uses.

Because this base is made specifically for the Tikka 658, it is intended to match the rifle correctly rather than relying on a generic fit. That rifle-specific approach is important in detachable mounts, where alignment and repeatability are more valuable than simple attachment alone. As part of the EAW Pivot Mounts family, this rear base belongs to a system known for allowing the optic to be removed and reattached while maintaining point of impact, which is especially useful on hunting rifles that may alternate between scoped and open-sight use or between different optics.

The component’s black finish keeps its appearance understated on the rifle, while its German-made construction suits the precise mechanical role expected of a pivot-mount base. For a Tikka 658 owner assembling or replacing an EAW detachable mount, this rear base provides the correct foundation at the rear of the system.

About EAW

EAW traces its history back to 1919, when Ernst Apel founded the company in Würzburg, Germany. The business produced its first riflescope mounts in 1945, and since 1951 the development and production of riflescope mounts have been its primary focus. That long specialization is central to EAW’s reputation in the sporting and hunting optics market, where precise fit, repeatability, and durable mechanical design are essential.

Over time, EAW expanded its mount portfolio to include pivot, slide-on or roll-off, and claw mounts for riflescopes, reflecting a strong emphasis on firearm-specific mounting solutions rather than generic hardware. Production moved from Würzburg to Gerbrunn in 1970, and Ernst Apel GmbH is now headquartered in Eibelstadt, Germany. In addition to mounts, EAW also offers thermal imaging cameras, but the brand remains especially associated with German-made scope mounting systems for hunting and sporting rifles.
