EAW XS Front Base for Pivot Mount Winchester 70 (C: 8.3mm)

• Repeatable pivot interface: The XS front base is built for EAW pivot mounts, so the optic can be removed and reattached without changing the mounting concept. That is especially useful on rifles that alternate between different scopes or aiming devices.
• Steel construction: A steel base gives the mounting point the rigidity needed for hard field use and repeated attachment cycles, helping the system stay stable under recoil and daily handling.
• Made for Winchester 70 actions: This front base is shaped for Winchester 70 variants and related compatible actions, giving the pivot mount a correct mechanical starting point instead of relying on universal-fit parts.
• 0 MOA alignment: With no built-in inclination, this base keeps the mounting geometry neutral. That suits general hunting and sporting rifle setups where a straightforward optical zero is preferred.
• Part of the XS pivot system: As an XS-pattern front base, it works within EAW’s detachable pivot-mount design, which is valued for secure lock-up, repeatable positioning and practical scope changes in the field.

About the EAW Magnum Pivot Mounts Series

EAW Magnum Pivot Mounts belong to a long-established family of detachable rifle mounts built around the company’s pivot-mount concept, which EAW brought to market in 1970. Within the broader EAW pivot range, the series sits among the brand’s dedicated solutions for shooters who want a mount that can be removed and reinstalled while maintaining a consistent point of impact. That makes the system especially relevant for hunting rifles that may carry more than one optic or alternate between a riflescope and another aiming device.

A defining characteristic of the series is its adjustable front and rear feet, allowing mount height and eye-relief position to be configured to the rifle and optic combination. EAW also designed the rear foot to engage the lock automatically, so the mount can be attached or removed with one hand. In practical use, that means quicker optic changes with less fuss in the field. The pivot design is also intended to keep the scope seated without unnecessary stress, which supports repeatability when the optic is taken off and put back on. Within EAW’s lineup, the Magnum and related pivot-mount variants are known for combining traditional detachable-mount handling with precise rifle-specific fit.

About the EAW XS Front Base for Pivot Mount Winchester 70 (C: 8.3mm)

The EAW XS Front Base for Pivot Mount Winchester 70 (C: 8.3mm) is the front anchoring element of a rifle-specific pivot-mount setup for Winchester 70-pattern actions and related compatible rifles. Its job is simple but critical: it establishes the forward bearing point that allows an EAW pivot mount to seat correctly, swing into position and return to the same mechanical interface after removal. For shooters who use detachable optics, that repeatability matters as much as raw strength.

The base is made from steel, a practical choice for a component that must resist wear at the contact surfaces and remain dimensionally stable over many attachment cycles. In the field, that helps the mount stay dependable on hunting rifles that are carried often, exposed to knocks and used with heavier calibres or larger optics. The black finish keeps the part visually discreet and matches conventional sporting-rifle hardware.

Its 0 MOA inclination makes it suitable for straightforward scope installations where the priority is a neutral mounting platform rather than built-in elevation bias. The listed A dimension of 21mm and the model-specific C: 8.3mm designation identify this as a precise fit component within the EAW system rather than a generic base. In practice, that rifle-specific approach is what makes pivot mounts work properly: correct geometry at the base level supports secure lock-up, smooth operation and consistent optic positioning every time the mount is reattached.

About EAW

EAW traces its origins to 1919, when Ernst Apel founded the company in Würzburg, Germany. The business later moved production from Würzburg to Gerbrunn in 1970, and Ernst Apel GmbH is now headquartered in Eibelstadt, Germany. Since 1951, the company’s primary focus has been the development and production of riflescope mounts, which remains the core of its reputation in sporting and hunting optics.

EAW is particularly associated with pivot mounts, but its range also includes slide-on or roll-off mounts and claw mounts for riflescopes. The company developed and produced its first riflescope mounts in 1945, giving it long-standing experience in detachable mounting systems and rifle-specific fit solutions. In addition to mounts, EAW also offers thermal imaging cameras, showing that its expertise extends across adjacent hunting-optics categories while remaining strongly rooted in precision mounting hardware.
