Rusan Clamp to Fit 56mm Objective Lens - Further Information

Each clamp secures around the riflescope’s objective housing using a quick-detach lever. A compatible device-specific adapter ring connects the clip-on optic to the clamp through a bayonet fitting, providing a secure, repeatable connection for hunting and field use.

The modular design allows you to select the scope-side clamp and device-side connector separately to suit your equipment. A compatible adapter ring is required and sold separately.

Choosing the Correct Size

Check the external diameter of your riflescope’s objective housing before selecting a clamp. The objective lens size shown in a scope’s name refers to the glass diameter, which is different from the outside diameter of the housing.

Where an option is described by its intended objective lens size, confirm that its actual clamp diameter matches your scope. Riflescopes with the same objective lens size can have different external dimensions.
