This NVG has a Chinese D-M2021 housing, featuring a built-in IR illuminator and a light sensor that will turn on the NVG if exposed to too much light.
The tube inside is a Photonis XR-5 - XX3066 Tube with pretty decent performances.
The mounting type is 'mini-rail', I 3D printed an adaptator to mount on my helmet, but commercial adaptors can be found.
Excuse the quality of the photos, they are not representative of the real view, it is quite difficult to capture it well.
Shipping in Europe possible. More Photo available on requests.
