Rusan Pivot Mount Bases for Mauser M12 (Sr. nm. <30000)

• Rifle-specific fit: made for the Mauser M12 with serial numbers below 30000, giving a base geometry that matches the receiver correctly and helps maintain secure, repeatable mounting.
• Steel construction: the all-steel build adds the rigidity needed for a durable optic interface, which is especially important on hunting rifles that see repeated recoil and field use.
• Low 5.50 mm profile: the compact base height keeps the optic closer to the bore, supporting a more natural cheek weld and a cleaner overall rifle setup.
• Pivot-mount compatibility: designed for the Rusan Pivot Mounts system, these bases form the fixed rifle-side platform for a quick-detach pivot setup that can be removed and reattached with consistent positioning.
• 0 MOA inclination: the neutral base angle suits general hunting and everyday sporting use, keeping scope alignment straightforward on rifles intended for conventional zero distances.

About the Rusan Pivot Mounts Series

Rusan Pivot Mounts are part of the company’s dedicated line of firearm optics mounts, built around a traditional pivot-style quick-release concept for hunters and shooters who want a removable scope setup without giving up a solid mechanical connection. The series includes both complete mounts with bases and pivot mounts sold without bases, which makes the system adaptable to different rifles and optic interfaces.

Within the range, Rusan offers model-specific versions for a wide variety of rifle makes, along with variants for different mounting standards such as 11 mm prism and Picatinny rail interfaces. Complete pivot mounts are also offered for several scope tube diameters and rail formats, showing that the series is intended to cover both classic hunting rifles and more modern optic configurations. A defining characteristic of the line is its steel construction and quick-release fixation, combining the familiar handling of a pivot mount with the robust feel expected from traditional European hunting mounts.

About the Rusan Pivot Mount Bases for Mauser M12 (Sr. nm. <30000)

Rusan Pivot Mount Bases for Mauser M12 (Sr. nm. <30000) are the rifle-side foundation for building a pivot-mount setup on early Mauser M12 rifles. Their main role is simple but important: they provide the correctly shaped attachment points that allow a compatible Rusan pivot mount to seat properly on the receiver. Because this version is made specifically for rifles with serial numbers below 30000, it addresses the fit requirements of that action pattern rather than relying on a generic base design.

The use of steel is especially relevant in this category. On a mount base, rigidity and wear resistance matter more than cosmetic weight savings, because the base has to remain stable under recoil and repeated removal or installation of the upper mount. The 5.50 mm base height helps keep the mounting platform low, which supports better scope positioning and a more natural head position behind the rifle. With 0 MOA inclination, the bases are suited to straightforward hunting and sporting setups where a neutral scope base is preferred.

Details such as the 4-hole layout and 6-48 thread reflect a conventional, secure attachment method, while the black finish keeps the appearance discreet on a field rifle. For shooters building a classic detachable hunting optics setup, these bases provide the essential first step in the Rusan pivot system.

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, establishing the area that still defines much of its product range today.

Rusan focuses on practical firearm and optics interfaces, including scope mounts, scope rings, Picatinny rails, and firearm tuning products. The company is also well known for adapter solutions for clip-on devices, night-vision units, and thermal-imaging attachments. A notable step in that direction came in 2009, when Rusan introduced its clip-on sight adapter clamp. That mix of traditional mount-making and modern adapter design makes the brand particularly relevant in the hunting optics and mounting category.
