Rusan M3.5 Screw for Rings (L=11 mm)

• M3.5 ring screw with 11 mm length: This replacement screw is sized for Rusan ring assemblies, helping restore proper clamping force so the optic stays secure under recoil and regular field use.
• Steel construction: The steel body resists thread wear better than softer materials, which matters when rings are removed, reinstalled, or retightened during maintenance.
• Low 1.00 g weight: The screw adds virtually no bulk to the mount, making it a practical spare part to keep in a field kit or workshop drawer.
• Made for mounts: As a dedicated mounting accessory, it is intended to keep Rusan ring systems serviceable rather than replacing the entire mount for one worn or missing fastener.
• Black finish: The dark finish blends with scope rings and mount hardware, maintaining a uniform appearance on hunting optics and rifle mounting setups.

About the Rusan Accessories Series

Rusan Accessories covers the small but important parts that keep the company’s mounting and adapter systems working as intended. The series includes adapter accessories, spare parts, mounting components, and reduction elements used across Rusan’s broader ecosystem of scope mounts, rings, Picatinny and Weaver rails, and clip-on interfaces. A key idea behind the range is modularity: Rusan developed accessories that support using one clip-on device with multiple rifles or matching different devices to different riflescopes without rebuilding the whole setup.

Within the series, the emphasis is on practical compatibility and serviceability rather than cosmetic add-ons. Rusan offers both conventional and modular adapter systems, and the accessory line supports those systems with the parts needed for fitting, maintenance, and replacement. That makes the series relevant not only to users of night-vision and thermal clip-on equipment, but also to shooters who rely on Rusan scope mounts and rings and want to keep them in proper working order over time.

About the Rusan M3.5 Screw for Rings (L=11 mm)

The Rusan M3.5 Screw for Rings (L=11 mm) is a small mounting part, but it plays a direct role in keeping a riflescope ring assembly properly secured. Designed as a steel screw for Rusan ring systems, it is intended for replacing a damaged, worn, or missing fastener without changing the complete mount. In practice, that helps maintain the original fit of the rings and keeps the optic clamped with the hardware type the mount was designed around.

The 11 mm length matters because ring screws need the correct thread engagement to hold the upper ring half evenly without bottoming out or leaving too little purchase. Used in the correct application, this supports consistent clamping pressure across the scope tube and reduces the risk of movement caused by uneven tightening. Its 1.00 g weight makes it easy to carry as a workshop spare or as part of a field repair kit, especially for shooters who travel with backup mounting hardware.

The black finish keeps the screw visually discreet on matte-finished rings and mounts, while the dedicated role as an accessory for mounts makes it a practical maintenance item for hunting optics and general riflescope mounting work. For users already invested in Rusan hardware, this screw is a straightforward way to keep an existing ring set serviceable and complete.

About Rusan

Rusan-Mikron is a Croatian manufacturer based in Marija Bistrica, Croatia, 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 explains why Rusan remains closely associated with practical firearm mounting solutions and precision-machined parts.

Today, the company manufactures scope mounts, scope rings, Picatinny rails, and firearm tuning products, along with adapter clamps and interfaces for night-vision and thermal-imaging devices. Rusan introduced its clip-on sight adapter clamp in 2009, and that product family became an important part of its reputation. Across both traditional mounting hardware and clip-on adapters, the company is known for building components that focus on fit, compatibility, and repeatable attachment.
