This front adapter is part of the Rusan Modular system, designed to quickly and securely mount a night vision or thermal imaging device in front of your rifle scope.

The system consists of this front adapter and a adapter ring.
THis adapter mounts around the objective lens of your rifle scope, while the adapter ring attaches to your night vision or thermal device. Thanks to the smart locking mechanism, both parts click together easily and firmly.

The robust and quick locking system allows for rapid attachment and removal, without affecting the zero of your pre-sighted rifle scope!

Choosing the right Rusan Clamp

This front adapter clamp is available in various diameters.
Make sure the adapter diameter matches the outer diameter of your rifle scope’s objective housing.

For example: an Element Helix HDLR 2-16x50 has a 50mm objective lens, but the outer housing diameter is 57mm.
In this case, the 57mm front adapter is the right fit.
