Description

The Rusan ARM52-50 is the industry-standard mounting solution for hunters using compact or mid-sized optics. The 50mm sizing is a very common requirement for riflescopes with a 42mm or 44mm objective lens, as the outer chassis usually adds roughly 6-8mm to the glass diameter.

Unlike cheaper alternatives that use plastic inserts, the Rusan adapter is a one-piece metal construction. It features a specialized blue internal anti-friction lining that protects your scope’s finish while providing enough grip to prevent any rotation under heavy recoil. The adjustable blue QR lever allows for lightning-fast installation and removal in the field, ensuring you can switch to thermal mode in seconds without losing your point of impact.
