Rusan Single Ring (Blaser mount), 25.4 mm

• Single upper ring part: This ring is supplied as one piece, making it a practical replacement part when an existing Blaser mount needs one upper section rather than a complete new set.
• 25.4 mm / 1 inch scope fit: The ring is sized for 25.4 mm scope tubes, giving secure support for classic 1 inch riflescopes commonly used on hunting rifles.
• Steel construction: A steel ring offers the rigidity and wear resistance needed in a mount component, helping the scope stay clamped consistently through repeated use.
• Blaser mount compatibility: Designed for the Blaser mounting system, this ring matches the platform used on Blaser rifles, so it suits repairs, maintenance, or parts replacement within that setup.
• Low-profile KR 0.0 mm configuration: The non-extended configuration keeps the part simple and compact, which is useful when restoring the original geometry of a mount assembly.

About the Rusan Spare Parts Series

Rusan Spare Parts covers the manufacturer’s replacement and component range for scope mounts and rings, with a focus on keeping existing mounting systems in service rather than replacing complete assemblies. Within this family, upper ring parts are listed among the scope-mount and ring components in the “Other mounts parts” category, reflecting their role as service parts for users who need to repair or complete a mount.

The series includes individual ring pieces sold as one part, not only complete ring sets, which is useful for gunsmiths and shooters maintaining specific rifle and scope combinations. Across the range, Rusan offers multiple diameters such as 26 (25.4), 30, 34, 35, 36, and 40 mm, along with different height and attachment variants depending on the mount design. The overall idea behind the series is straightforward: preserve compatibility with existing Rusan mounting systems, support precise fitment, and provide the small but essential components needed to keep a proven optic setup working properly.

About the Rusan Single Ring (Blaser mount), 25.4 mm

The Rusan Single Ring (Blaser mount), 25.4 mm is a replacement upper ring part intended for a Blaser-compatible scope mount using a 25.4 mm - 1" riflescope tube. Its role is simple but important: it restores or completes the clamping section that secures the scope tube in the mount. For shooters using established 1 inch hunting optics, that makes it a practical part for maintenance, repair work, or replacing a damaged ring half without changing the entire mounting system.

Its steel construction is well suited to this task because a ring must hold shape under screw tension and maintain even pressure around the scope tube. In practice, that helps protect alignment and supports repeatable clamping when the mount is assembled correctly. The black finish keeps the appearance consistent with most riflescope mounts and hunting rifle setups, while the KR 0.0 mm configuration indicates a non-extended form that preserves the original layout of the mount assembly.

Because this is a single ring sold as one piece, it is especially relevant for users who do not need a full mount, only the correct upper section for a Blaser setup. That makes it useful both as a workshop spare and as a direct replacement part in a field rifle system where maintaining the original mount geometry matters.

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, building its reputation around precision-made mounting solutions for sporting and hunting firearms.

Today, Rusan focuses on scope mounts, scope rings, Picatinny rails, and firearm tuning products, along with adapter systems for night-vision and thermal devices. The company is also known for its clip-on sight adapters, including the adapter clamp it introduced in 2009. That background is directly relevant here: Rusan’s long specialization in mounting hardware shows in products designed for platform-specific fit, practical serviceability, and compatibility across a wide range of rifles and optics.
