Description

The Rusan ARM52-57 is a critical accessory for hunters using “front-mount” thermal units. The 57mm size is frequently used for mid-to-large objective riflescopes where the outer chassis diameter measures exactly 57mm.

What sets the Rusan adapter apart is its ultra-slim wall design, which allows for mounting even on rifles where the gap between the scope and the barrel is minimal. The interior is lined with a specialized blue anti-friction tape that serves two purposes: it protects the scope’s finish from scratches and ensures the adapter does not shift or rotate under the recoil of high-caliber rifles. The signature blue QR lever allows for silent, rapid attachment in the field, ensuring you can transition to thermal imaging without losing your tactical advantage.
