Rusan Single Ring, 35 mm

• Single upper ring part: Supplied as one piece, this ring is suited to repairs, replacements, or custom mount builds where only the upper section is needed instead of a complete ring set.
• 35 mm scope fit: The 35 mm ring size matches larger riflescope tubes securely, helping maintain even clamping pressure and stable optic alignment.
• Steel construction: A steel body gives the ring the rigidity and wear resistance needed for repeated installation and long-term use on hunting optics or precision shooting setups.
• Rusan 8 mm interface compatibility: Designed for the Rusan Ø 8 mm Interface, this upper ring integrates with the matching lower mounting system for a correct mechanical fit.
• Black finish: The black surface keeps the part visually discreet and consistent with most scope mounts and riflescope bodies.

About the Rusan Spare Parts Series

Rusan Spare Parts is the manufacturer’s parts range for maintaining, rebuilding, or adapting its scope-mount systems rather than replacing a complete mount assembly. Within this family, upper ring parts are offered as individual components, which is useful for gunsmiths, experienced shooters, and anyone restoring a damaged or incomplete mounting setup. The series is organized as part of Rusan’s broader scope-mount and ring-parts program and includes multiple diameters, with listings that cover 26, 30, 34, 35, 36, and 40 mm rings.

The range is built around practical compatibility. Rusan identifies these components as one-piece ring parts, and the listings also include attachment designations such as 8/M5 and 8/M6 to match different mounting arrangements within the system. In the wider series, different heights are available for some diameters, which makes the line useful not only for replacement work but also for fine-tuning optic position. The overall design philosophy is straightforward: keep the original Rusan mounting geometry, preserve fit between matching parts, and let users replace only the component they actually need.

About the Rusan Single Ring, 35 mm

The Rusan Single Ring, 35 mm is an upper ring part intended for users who need to replace a worn, damaged, or missing ring half in a compatible Rusan mounting setup. Because it is made for a 35 mm scope tube, it suits modern riflescopes with larger main tubes, where correct ring diameter is essential for secure clamping and for avoiding stress on the optic body. In practice, that means a cleaner fit and more dependable retention than trying to adapt an incorrect ring size.

The use of steel is especially relevant on a part like this. A steel upper ring resists deformation under screw tension better than softer materials, which helps maintain even contact around the scope tube when the mount is assembled correctly. That matters on rifles used for hunting or range work, where the optic must stay stable after repeated firing, transport, and reinstallation. The black finish keeps the part visually unobtrusive and consistent with most riflescope mounts.

This model is also built around the Rusan Ø 8 mm Interface, so its value lies in system compatibility as much as in the ring itself. For users already working within the Rusan ecosystem, that makes this part a practical way to restore an existing mount without replacing more hardware than necessary. The KR 0.0 mm extension keeps the geometry straightforward, making this ring suitable where no additional offset is required.

About Rusan

Rusan is a Croatian manufacturer whose roots go back to 1983, when the Rusan family’s metalworking business began. Željko Rusan opened a gunsmith shop in 1986, and the company moved into scope-mount production in 1993. Based in Marija Bistrica, Croatia, Rusan-Mikron focuses on precision-made shooting accessories, especially scope mounts, scope rings, Picatinny rails, and firearm tuning products.

The company is particularly well known for mounting solutions and adapters that connect optics to rifles in a practical, repeatable way. Its range includes rails for rifle platforms such as Tikka T3, Sauer 202, and Zastava M70, as well as adapter systems for clip-on night-vision and thermal devices. Rusan introduced its clip-on sight adapter clamp in 2009, reinforcing its reputation for mechanical solutions that bridge conventional daytime optics with modern electro-optics.
