The Rusan MCR-M52 Modular Connector links your thermal or night vision clip on to the Rusan MAR clamp system. One side has an internal M52x0.75 thread that screws onto your device. The other side carries the Rusan bayonet locking lugs, which lock into a MAR clamp fitted to your riflescope. The connector stays on your device, so attaching and removing your clip on becomes quick and repeatable.
Made from durable aluminium, the MCR-M52 is the one connector you need per device. It pairs with any size of Rusan MAR clamp, so a single clip on can move between rifles fitted with different scopes. It also works with the Rusan 2.5x Magnification Ocular for handheld use.
