Rusan Pivot mount for Sauer 303, ATN 4K, one-piece

• Pivot mounting system: The pivot design lets the sight return to the same mounting position after removal, which is useful when a rifle alternates between daytime and digital night-use setups.
• One-piece ATN 4K interface: Built specifically for the ATN 4K in a 30 mm format, this mount provides a direct, model-matched fit instead of relying on improvised ring combinations.
• Sauer-specific compatibility: Made for the Sauer 303 (ISI) platform and also listed for Sauer ISI mount and Sauer 202 GTI (ISI), it simplifies installation on rifles that use this interface.
• Quick-detachable handling: A detachable pivot mount is practical for transport, storage, or switching optics, while keeping the rifle ready to accept the sight again without a full remounting process.
• Steel construction: A steel mount body gives the assembly the rigidity needed for repeatable alignment and long service life on hunting rifles that see regular field use.

About the Rusan Pivot Mounts for NV and Thermal Series

Rusan Pivot Mounts for NV and Thermal are built around one clear purpose: giving hunters and shooters a dedicated way to fit night-vision and thermal devices to rifles that use traditional pivot-style mounting interfaces. In Rusan’s catalog, this series covers a wide spread of rifle connection types, including 11 mm, 16.5 mm, and 19 mm prism variants, along with model-specific solutions for many popular European hunting rifles. That approach makes the series especially relevant for users who want a cleaner, more integrated alternative to generic adapter-based mounting.

A defining characteristic of the range is its combination of rifle-specific lower interfaces with device-specific upper sections. Rusan lists versions for digital and thermal units from brands such as ATN, HIKMICRO, InfiRay, Pulsar, Yukon, and others, so the mount geometry is matched to the optic it is meant to carry. The series also includes both complete pivot mounts with bases and upper parts without bases, which helps when replacing or expanding an existing setup. In practice, these mounts are aimed at hunters who need a secure, detachable solution that suits classic rifle lines while supporting modern electro-optics.

About the Rusan Pivot mount for Sauer 303, ATN 4K, one-piece

The Rusan Pivot mount for Sauer 303, ATN 4K, one-piece is a dedicated mounting solution for pairing an ATN 4K digital sight with rifles that use the Sauer 303 (ISI) interface. Because it is a one-piece design made around this specific sight format, it avoids the extra variables that can come with mixing separate rings, adapters, and bases. That matters on digital optics, where stable alignment and consistent positioning help preserve practical zero retention after removal and refitting.

This mount is also relevant for users of the Sauer ISI mount and Sauer 202 GTI (ISI), giving it value across closely related rifle setups. The pivot format is well suited to hunting use because it allows the optic to be detached when needed for transport or rifle maintenance, then reattached in the same mounting relationship. For shooters who move between different sighting systems, that makes the rifle more flexible without abandoning a traditional, low-profile mounting style.

Steel construction adds the rigidity expected from a mount intended for field use, while the black finish keeps the assembly visually discreet on the rifle. As a mount built specifically for the 30 mm ATN 4K configuration, it is best understood not as a generic accessory, but as a purpose-matched interface between a Sauer hunting rifle and a digital day/night optic.

About Rusan

Rusan-Mikron is a Croatian manufacturer based in Marija Bistrica, and the company’s roots go back to a family metalworking business that dates to 1983. Željko Rusan opened a gunsmith shop in 1986, and the company began producing scope mounts in 1993. That background is important because it explains why Rusan remains closely associated with practical mounting solutions for sporting and hunting rifles.

Today, Rusan manufactures scope mounts, rings, Picatinny rails, and firearm tuning products, along with adapter systems for night-vision and thermal-imaging devices. The company is especially well known for its clip-on adapter clamps, introduced in 2009, and for a catalog that covers many rifle-specific mounting interfaces. In this product category, Rusan’s reputation rests on making model-matched steel mounting components for shooters who want a precise mechanical fit rather than a universal compromise.
