Rusan Q-R adapter M52x0.75 for Ø54 mm (ARM52-54)

What it is and what it is for

Clamp-style adapter to mount clip-on night vision devices and thermal cameras that have an M52x0.75 thread onto day optics with a 54 mm external diameter. It enables fast and secure attachment and removal of the device for use or transport.

Features

The adapter has an internal thread M52 x 0.75 for screwing onto compatible devices and is available in the 54 mm external diameter variant (ARM52-54). It is a Q-R (quick release) adapter designed for rapid coupling and release. The manufacturer lists the weight as 164 g. In typical assemblies, the adapter adds approximately 3 mm to the overall mounted length. The clamping system includes locking points that allow a bayonet-type coupling with a quick-release lever and four locking lugs to secure the accessory.

Compatibility

Part of the ARM52 family, it is intended to couple a wide range of clip-on, night-vision and thermal units using the M52x0.75 thread. Common compatible examples include Guide TAxxx, Leica Calonox 2, Burris BTC, Nitehog Viper, Lahoux Clip and Steiner Nighthunter C35, provided thread and mounting diameter match.

Installation and use

The adapter screws onto the device via the M52x0.75 thread and fixes to the objective or scope with the clamp/clip quick-release system for repeatable, stable coupling suitable for night or thermal observation. Verify that your device and objective match the specified thread and diameter before mounting.
