Rusan Pivot Mount Bases for CZ 527, ZKM, Fox, Hornet (16,5 mm prism)

• Model-specific prism fit: Made for the CZ 527, ZKM, Fox and Hornet 16,5 mm prism, these bases give the pivot mount a correct interface on the rifle, which helps maintain secure alignment and dependable scope positioning.
• Steel construction: The steel body provides the rigidity needed in a mounting system, reducing flex under recoil and supporting consistent optic seating over long-term use.
• Low-profile geometry: With a 5.50 mm height and 0 MOA inclination, the bases keep the mounting platform close to the action for a compact setup and a straightforward optical centerline.
• Built for the Rusan pivot system: As part of the Rusan Pivot Mounts family, these bases are intended to work with the matching upper pivot components, giving the user a detachable scope setup built around repeatable mechanical engagement.
• Precise attachment layout: The 4-hole pattern and 6-48 thread support a stable installation on the rifle, helping the mount resist movement and preserve zero in regular field use.

About the Rusan Pivot Mounts Series

Rusan Pivot Mounts are a family of rifle scope mounting solutions built around a detachable pivot-style design for hunters and shooters who want a secure optic interface with the option to remove and reinstall the scope assembly. Within Rusan’s mount lineup, the series covers a wide range of rifle-specific platforms, including versions for 11 mm prisms, Picatinny rails and other model-dependent receiver interfaces. That makes the system relevant both for traditional hunting rifles and for more specialized firearm setups.

The series includes complete pivot mounts with rings for common scope tube diameters such as 26 (25.4), 30, 34, 36 and 40 mm, as well as upper assemblies sold separately for users who already have the correct bases installed. A consistent theme across the range is steel construction and quick-release fixation, which suits shooters who value mechanical strength and repeatable handling in the field. In practical terms, the Rusan Pivot Mounts series is designed for rifle-specific fit, solid lock-up and a traditional detachable mounting concept that remains relevant for hunting optics where reliability and clean rifle handling matter.

About the Rusan Pivot Mount Bases for CZ 527, ZKM, Fox, Hornet (16,5 mm prism)

Rusan Pivot Mount Bases for CZ 527, ZKM, Fox, Hornet (16,5 mm prism) are the rifle-specific foundation of a pivot-mount setup for these compact CZ-pattern actions. Their main role is to provide the correct mechanical interface between the rifle’s 16,5 mm prism and the matching Rusan pivot upper assembly. That model-specific fit matters because a detachable mount only performs properly when the base geometry matches the receiver precisely; it is the base that establishes alignment, seating and long-term stability.

The use of steel is especially important in this part of the system. Bases carry the load of the optic and mount under recoil, and a rigid steel platform helps the upper pivot components return to the same position after removal and reinstallation. The 5.50 mm height keeps the base section compact, which helps preserve a tidy rifle profile and supports sensible scope height when combined with the appropriate upper mount. With 0 MOA inclination, these bases are intended for a neutral mounting plane, suitable for general hunting and sporting use where the shooter wants straightforward optic setup rather than built-in cant.

The 4-hole layout and 6-48 thread show that these bases are built as a proper receiver-mounted component rather than a generic clamp-on part. In practice, that means a more secure attachment and better resistance to movement over time. For owners of a CZ 527, ZKM, Fox or Hornet using the 16,5 mm prism interface, these Rusan bases are the essential lower half of a pivot mount system that prioritizes correct fit, durability and repeatable scope mounting.

About Rusan

Rusan-Mikron is a Croatian manufacturer based in Marija Bistrica, with roots in the Rusan family’s metalworking business dating back to 1983. Željko Rusan opened a gunsmith shop in 1986, and the company began producing scope mounts in 1993. That background is relevant because Rusan’s product range remains closely tied to practical firearm and optics mounting needs rather than general engineering alone.

Today, Rusan is known for manufacturing scope mounts, scope rings, Picatinny rails and firearm tuning products, along with adapters for night-vision and thermal-imaging devices. The company introduced its clip-on sight adapter clamp in 2009, a product type that helped establish its reputation among users of modern hunting optics and observation devices. Across categories, Rusan’s strength lies in precise metal components for connecting optics to rifles securely and correctly.
