Rusan MAR-52 Adapter
Scope-Side Mount for Leica Calonox Modular System
The Rusan MAR Clamp Adapter is the scope-side component of the modular system that enables secure, repeatable mounting of the Leica Calonox Sight or Calonox 2 thermal units to your rifle scope. Precision-machined and available in multiple diameters, it locks onto the objective bell of your riflescope and mates with the corresponding Rusan MCR-M43P (for Calonox 2 Sight and Calonox 2 Sight LRF) or MCR-M52 (for Calonox Sight and Calonox Sight SE) connectors.
Note: This listing is for the scope-side clamp only. Must be used in combination with the appropriate Rusan MCR adapter to complete the system.
Fit Guidance
To select the correct size, measure the outer diameter of your riflescope’s objective bell and choose the matching MAR clamp (e.g., MAR-52 for a 52 mm housing).
The essentials:
- Available in sizes from 30 mm to 80 mm to match your scope’s objective bell
- Cam-locking quick-detach mechanism – no tools required after initial fitment
- Maintains point-of-impact across mounting cycles
- Non-marring interior protects scope housing
- Lightweight, hard-anodized aluminum
