Versions

Modular Rusan system
Clamp plus connector make the adapter
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.
Connector: chosen by the clip-on device
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.
Locking
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.
Advantages according to Rusan
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.
Features in practical use
Fixed with three screws
At Rusan MAR-FX is the fixed version with three screws; the quick-release version is called MAR.
Size by the objective tube
Rusan marks the clamps with the outside diameter of the objective tube, not with the lens size. Every clamp can be adjusted by +/- 0.2 mm, not more.
Rail versions
For riflescopes with rail Rusan lists among others the codes 30ZM-1 to 30ZM-4 and 34SR; which riflescope belongs to which code is stated in each version.
Mounting according to Rusan
The three screws are loosened to a gap of about 3 to 4 mm; the middle screw is tightened first, then the other two, with a torque limit of 1.2 Nm.
MCR connector required
The clamp is only one half of the system: according to Rusan a complete adapter also needs the connector (MCR) that matches the thread or bayonet of the clip-on device.
Advantages of the modular system
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.
Matching items
Without an MCR connector the adapter is not complete: the connector is chosen by the thread or bayonet of the clip-on device. The version with quick-release lever (MAR) is a separate Rusan product.
