Night vision sight D777  is a compact and light weighted sight for different tasks. Aiming reticle has red illumination with a smooth brightness adjustment.
Tube’s brightness adjustment function allows to use the sight in the twilight, and other conditions where there are bright light sources (such as the setting sun) and it is necessary to reduce the brightness of the image. Tube’s mounting system and adjustment system provide stability of the average point of impact at impact loads up to 600G, that corresponds to a cartridge.300 Weather by Magnum with initial bullet energy of 5920 J.
Features:
- body made of light alluminium alloys;
- comfortable thin red reticule with adjustable lighting;
- a catadioptric lens with the frequency-contrast characteristic;
- adjusting the distance is produced by the handle, which provides an internal focus of the lens;
- possibility to install powerful IR illuminator for both sides of device;
- shock resistance up to 600G;
- various types of mounting on weapons;
- light weight, compact.
