Find the right RUSAN clamp adapter ARM M52x0.75 for your thermal or night vision scope. Learn about sizes, thread compatibility, and how to choose.
Quick answer
The RUSAN Klemmadapter ARM M52x0.75 is a versatile clamp adapter for connecting thermal and night vision add-on devices to a day scope. Choose the diameter that matches your objective lens housing, not the thread pitch alone.
Why diameter matters more than thread pitch
The M52x0.75 thread is the standard interface on many thermal and night vision add-on devices, but the adapter's clamping diameter must fit the outer diameter of your day scope's objective bell. RUSAN offers this adapter in several diameters, so you need to measure your scope's objective housing precisely before ordering.
A common mistake is assuming all M52-threaded adapters are the same size. The clamping range varies by model, and using the wrong diameter can cause poor fit, image shift, or damage to the scope.
Compatibility with thermal and night vision devices
This adapter works with most thermal and night vision add-on devices that have a female M52x0.75 thread, such as popular models from Pulsar, Hikmicro, and Nocpix. It is not limited to a single brand, making it a flexible choice for shooters who swap devices between scopes.
However, the adapter does not include a built-in stop or locking mechanism beyond the clamp itself. For heavy or long devices, you may need additional support to prevent rotation under recoil.
How to choose the right RUSAN Klemmadapter ARM M52x0.75
- Measure your objective bell diameter: Use a caliper to measure the outer diameter of your day scope's objective housing in millimeters. Round to the nearest whole millimeter. This is the clamping diameter you need.
- Confirm your add-on device thread: Check that your thermal or night vision add-on has a female M52x0.75 thread. If it uses a different thread (e.g., M46 or M49), you will need a separate thread adapter first.
- Select the matching RUSAN diameter variant: Choose the RUSAN Klemmadapter ARM M52x0.75 in the diameter that matches your scope's objective housing. If your measurement falls between two sizes, choose the larger one and use the clamp's adjustment range. Double-check that the clamping range listed for the adapter includes your measured diameter.
- Consider recoil and device weight: For heavy add-on devices or high-recoil calibers, verify that the clamp provides enough grip. RUSAN adapters are CNC-machined from aluminum, but a secondary support ring may be needed for very heavy setups.
