Rusan Rear Pivot Mount Assembly, 40mm

• 40 mm ring interface: Built for optics with a 40 mm tube diameter, this rear pivot assembly provides the correct fit and support for large-tube scopes used on hunting rifles and specialist setups.
• Steel construction: The steel body adds the rigidity needed in a pivot-mount system, helping the optic stay aligned under repeated recoil and regular removal and reinstallation.
• Adjustable windage: Integrated windage adjustment gives extra latitude when aligning the scope in the mount, which helps achieve a centered zero without forcing excessive correction through the optic itself.
• 0 MOA inclination: The 0 MOA configuration suits general-purpose rifle setups where a neutral mounting angle is preferred for conventional hunting distances and straightforward sight-in.
• KR 0.0 mm extension: With KR 0.0 mm extension, this assembly keeps the mounting geometry neutral, making it suitable where no additional rearward or forward offset is required.

About the - Series

Rusan pivot-mount components are designed for shooters who want a removable scope setup with the solid lock-up expected from traditional steel mounting systems. In this part of the company’s range, the emphasis is on repeatable attachment, precise mechanical fit, and compatibility across different rifle and optic combinations. Rather than treating the mount as a simple accessory, Rusan approaches it as a structural part of the sighting system, where alignment, ring diameter, and base geometry all matter in practical field use.

Within the broader Rusan lineup, these assemblies sit alongside the company’s scope rings, rails, and adapter solutions for sporting and hunting firearms. The design philosophy is straightforward: durable metal construction, model-specific fit, and configurations that let the user match the mount to the optic’s tube diameter and the rifle’s mounting interface. For hunters and shooters who remove an optic for transport, maintenance, or switching between sighting systems, a pivot-style mount offers a practical balance between secure positioning and fast handling in the field.

About the Rusan Rear Pivot Mount Assembly, 40mm

The Rusan Rear Pivot Mount Assembly, 40mm is the rear section of a pivot-mount setup intended for riflescopes with a 40 mm tube diameter. Its role is not only to hold the scope, but to do so with the mechanical consistency needed in a detachable mounting system. For larger-tube optics, correct ring sizing is especially important because it affects clamping security, scope alignment, and long-term resistance to movement under recoil.

This version uses a steel construction and a 0 MOA inclination, making it suitable for conventional hunting and sporting rifle applications where a neutral mounting angle is preferred. The inclusion of adjustable windage is particularly useful in practice: it allows the mount to contribute to optical alignment, reducing the need to rely entirely on the riflescope’s internal windage adjustment. That can help preserve more of the scope’s adjustment range for zeroing and fine correction.

The specified KR 0.0 mm extension indicates a neutral rear geometry, so this assembly is intended for setups that do not require additional offset to achieve proper eye relief or scope position. Finished in black, it matches the subdued appearance expected of modern hunting optics hardware while keeping the focus on fit, strength, and dependable function.

About Rusan

Rusan-Mikron is a Croatian manufacturer based in Marija Bistrica, with roots in the Rusan family’s metalworking business dating to 1983. Željko Rusan opened a gunsmith shop in 1986, and the company began producing scope mounts in 1993. That background is reflected in a product range centered on practical firearm interface components rather than general outdoor equipment.

Today, Rusan is known for manufacturing scope mounts, scope rings, and Picatinny rails, along with firearm tuning products and adapter systems for night-vision and thermal devices. The company also developed adapter clamps for clip-on sights, introducing its clip-on sight adapter clamp in 2009. In this category, Rusan’s reputation rests on machining-focused design, broad rifle compatibility, and mounting solutions made for shooters who value precise fit and dependable mechanical engagement.
