Rusan MCR-M52 modular adapter ring (M52x0.75)

What it is and what it does

The Rusan MCR-M52 modular adapter is a connector designed to integrate optical devices with an M52x0.75 thread into the Rusan modular system. It is intended for quickly and securely coupling night-vision and thermal devices that use this thread pitch.

Key features

The adapter ring provides an internal M52x0.75 thread and a quick-lock mechanism that enables easy and fast coupling and uncoupling of the mating piece. The manufacturer lists a weight of 0.07 kg (70 g). The part is built for the Rusan modular (MAR/MCR) connector system to link compatible elements.

Compatibility

Compatible with devices using an M52x0.75 thread and with the Rusan modular system; the MCR-M52 reference covers multiple devices with that thread. No detailed list of specific models is provided in the available documentation.

Usage notes

The quick-lock mechanism allows repeated connections without tools for locking the ring. This adapter is a mechanical coupling component; any additional mounting accessories required for attachment to a firearm or rail must be sourced separately depending on the device it will be used with.
