Rusan Single Ring, 34 mm

• Single upper ring design: This ring is sold as one piece, making it a practical replacement part when one upper section is damaged or when a modular Rusan mount needs to be completed without buying a full ring set.
• 34 mm scope fit: The ring is made for 34 mm scope tubes, supporting the larger tube diameter commonly used on modern long-range and tactical optics while preserving correct clamping geometry.
• Steel construction: A steel body gives the ring the rigidity needed to hold optic alignment under recoil and repeated use, which matters when a mount must stay consistent after removal, transport, or hard field handling.
• Rusan Ø 8 mm interface compatibility: Compatibility with the Rusan Ø 8 mm interface allows this upper part to integrate into the brand’s mounting system, helping users replace only the worn or missing component instead of the entire mount.
• Black protective finish: The black finish keeps the part visually matched to most riflescopes and mounts while also helping the steel surface resist everyday handling marks and field exposure.

About the Rusan Spare Parts Series

Rusan Spare Parts covers the manufacturer’s replacement and component-level mount parts for shooters who want to maintain or adapt an existing setup rather than replace a complete assembly. Within this family, ring parts are listed under scope-mount and ring parts, and the manufacturer identifies these components as upper parts intended for use within its modular mounting system. That makes the series especially relevant for gunsmiths, experienced rifle owners, and anyone running a Rusan mount across multiple optics.

The series is defined by individual one-piece ring parts rather than complete ring pairs. Rusan offers these parts in several diameters, including 26, 30, 34, 35, 36, and 40 mm, with different attachment designations and height options shown across the range. In practical terms, the series is built around serviceability: replacing a single ring section, matching a specific tube diameter, or completing a mount with the correct upper component. That parts-based approach fits Rusan’s broader design philosophy, where mounts and adapters are made to be mechanically straightforward, durable, and easy to integrate into specialized hunting optics and shooting setups.

About the Rusan Single Ring, 34 mm

The Rusan Single Ring, 34 mm is a dedicated upper ring part for users who need a replacement or matching component within a Rusan mount system. Instead of forcing the purchase of a full ring set, this part lets a damaged, missing, or mismatched upper section be replaced directly. That is particularly useful on rifles fitted with premium 34 mm optics, where preserving the original mount geometry matters for repeatable alignment and even clamping pressure.

The ring is sized for a 34 mm scope tube, a format widely used on modern precision, tactical, and hunting riflescopes that need more internal adjustment range and robust tube construction. By matching that diameter exactly, the ring supports secure contact around the tube without the compromises that come from improvised shims or non-matching parts. Its steel construction is important here: steel provides the stiffness and wear resistance expected from a load-bearing mount component, helping the assembly stay stable under recoil and during repeated installation cycles.

This model also works with the Rusan Ø 8 mm interface, so it fits into the brand’s established mounting architecture rather than functioning as a generic standalone ring. The KR 0.0 mm extension indicates a straight, non-extended configuration, which suits setups where the optic already sits in the correct fore-and-aft position. Finished in black, the ring blends cleanly with most scopes and mount bases while maintaining the understated, functional look expected from serious mounting hardware.

About Rusan

Rusan-Mikron is a Croatian manufacturer based in Marija Bistrica, and the company’s roots in metalworking go back to 1983. The business expanded from gunsmithing into dedicated mount production, with Željko Rusan opening a gunsmith shop in 1986 and the company beginning to produce scope mounts in 1993. That background is important because it explains why Rusan products are strongly focused on machining quality, fit, and practical firearm use rather than on cosmetic design alone.

Today, Rusan is known for manufacturing scope mounts, scope rings, Picatinny rails, and firearm tuning products, along with adapter systems for clip-on night-vision and thermal devices. The company introduced its clip-on sight adapter clamp in 2009, and that product category remains one of the areas most closely associated with the brand. Across its optics-mounting range, Rusan has built a reputation for durable steel components and modular solutions that suit hunting rifles, precision setups, and specialized sighting equipment.
