A precise connection between your scope and your clip-on
When you use a thermal or digital clip-on, the quality of the mount is essential. The device must position itself correctly in front of the optical axis of your scope while remaining simple enough to install and remove in the field.
The Rusan Q-R M52x0.75 attaches around the objective of your sighting scope. Its clamping system allows you to keep your usual scope and add your clip-on when you need it.
On the device side, the adapter has a M52x0.75 threaded interface.
How to choose the right adapter diameter?
This is the most important point before placing an order.
The size of the adapter must match the OUTER diameter of the objective of your scope.
Therefore, you should not use the lens diameter indicated in the specifications of the scope.
Let's take a concrete example:
Does your scope indicate 3-8x56?
The 56 indicates the diameter of the objective lens: 56 mm.
This does not mean that the outer diameter of your scope measures 56 mm.
The body surrounding this lens has its own diameter, necessarily larger, and this varies according to the construction and manufacturer of the scope.
You should not automatically order a 56 mm adapter for a 3-8x56 scope.
How to properly measure your scope?
To choose your adapter, we strongly recommend using a caliper.
Place it around the objective of your scope, at the point where the adapter will tighten, then measure the outer diameter from one edge to the other.
This value, expressed in millimeters, should be used to choose the size of your Rusan adapter.
Example: your scope is a 3-8x56, but your caliper measures an outer diameter of 62 mm. You should choose the 62 mm adapter, not the 56 mm.
To remember
Diameter indicated on the scope = diameter of the lens.
Diameter needed for the adapter = outer diameter of the scope body.
In case of doubt, measure several times with your caliper before ordering. You can also contact us to verify the necessary size.
A wide choice of diameters
To allow mounting on many scopes, the Rusan Q-R M52x0.75 is available at The Hunter Camp in the following sizes:
30 - 34 - 36 - 38 - 39.2 - 40 - 41 - 42 - 42.5 - 44 - 46 - 47 - 48 - 49 - 50 - 51 - 52 - 53 - 54 - 55 - 56 - 57 - 58 - 59 - 60 - 61 - 62 - 63 - 64 - 65 - 66 - 67 - 68 - 69 - 71 - 72 - 80 mm
The selected size always corresponds to the outer diameter of your scope's objective..
Why choose the Rusan Q-R M52x0.75?
Keep your usual scope
The adapter allows you to use your clip-on in front of your scope without replacing your usual setup.
Precise mounting
The clamp around the objective ensures a direct connection between the scope and the clip-on system.
Quick mounting and dismounting
The Q-R system makes it easy to install and remove the adapter when switching from a classic setup to a clip-on setup.
M52x0.75 interface
The adapter has an M52x0.75 thread on the device side to accommodate compatible equipment or the necessary adapter ring.
Many diameters available
The wide range of sizes allows for precise adaptation of the mount to the outer diameter of many scopes.
For the HIKMICRO Cheetah
To mount a device from the HIKMICRO Cheetah range with this setup, the Rusan Q-R M52x0.75 must be complemented by the Rusan reduction ring compatible with HIKMICRO.
This ring is therefore an additional part of the mount and must be ordered separately.
Rusan Q-R + suitable reduction ring = complete mounting system for the relevant Cheetah.
What to remember
The Rusan Q-R M52x0.75 allows for a clean mounting of a compatible clip-on in front of your scope while keeping your usual setup.
But to get the right mount, do not rely on the diameter marked on your scope.
A scope 3-8x56 does not necessarily have an outer diameter of 56 mm. The number 56 corresponds to its objective lens.
Always measure the outer diameter of the objective with a caliper before choosing your adapter.
It’s a check that takes a few seconds and simply avoids ordering the wrong size.
FAQ - Frequently Asked Questions
Choose the adapter that corresponds to the outer diameter of your scope's objective, measured at the point where the adapter will attach.
No. The 56 corresponds to the diameter of the objective lens and not the outer diameter of the scope. Measure the latter with a caliper before selecting your adapter.
Ideally, use a caliper. Position its jaws on either side of the body of the objective, at the point where the adapter will be installed, then take the measurement in millimeters.
Yes. The point of this mount is precisely to be able to install a clip-on in front of your usual scope.
No. When a specific reduction ring is needed for your Cheetah HIKMICRO device, it must be ordered separately.
