Connector · Modular system · for the clip-on device
Modular connectors MCR by Rusan for clip-on devices: threads M35x1, M49x0.75 and M52x0.75 (with and without orientation) and bayonets for Pulsar Core, Pulsar F135/F155/F455, Hikmicro Cheetah/Thunder V.1, AGM Rattler, GPO Spectra and Pard. A complete adapter needs a MAR, MAR-SH or MAR-FX clamp matching the riflescope.

Choose by the thread or bayonet of the clip-on device; for bayonets the device is named in the selection. A P at the end of the Rusan code means a built-in orientation. Only the selected connector is supplied; the clamp is a separate item.
Modular Rusan system
The modular Rusan system has two parts: the clamp for the riflescope (MAR, MAR-SH or MAR-FX) and the MCR connector for the clip-on device. Rusan states that both have to be combined to have a complete system.
The clamp sits on the objective tube of the riflescope and is chosen by its outside diameter, not by the lens diameter.
The connector matches the thread or bayonet of the clip-on device. A P at the end of the product code means a built-in orientation (rotation) of the device, according to Rusan.
The locking nut of the clamp is turned to UNLOCK, the connector is put into the slots and the nut is turned to LOCK. According to the instructions one finger with moderate feeling is enough.
One clip-on device on several rifles, one rifle with several clip-on devices, exchanging between rifles and devices without losing precision, and fast mounting and dismounting in the dark.
The MCR connector is fastened to the clip-on device and put into the modular clamp on the riflescope. It has to match the thread or bayonet of the device.
The following connectors are available: threads M35x1, M49x0.75 and M52x0.75 (the latter with and without orientation) as well as bayonet connectors for Pulsar Core (2 pins), Pulsar F135, F155, F455 (4 pins), Hikmicro/AGM/GPO Spectra (3 pins) and Pard.
According to Rusan connectors with a P at the end of the code have a built-in system to orient the device; no counter-nut is needed on the device then. Here: MCR-M35P and MCR-M52P.
For each connector Rusan names the suitable devices (catalogue, modular connector table). The device names are stated in each version; for M52 Rusan names many devices without a list.
A connector alone is not a complete adapter. Rusan requires the combination with a modular clamp (MAR, MAR-SH or MAR-FX), chosen by the outside diameter of the objective tube.
Rusan lists: one clip-on device on several rifles, one rifle with several clip-on devices, exchanging without losing precision, fast mounting in the dark and no need to rotate the clip-on device when locking it.
Without a clamp the adapter is not complete: the clamp is chosen by the outside diameter of the riflescope objective tube. The connector has to match the thread or bayonet of the clip-on device.
