High light transmission and long operating time

In the design, the manufacturer used a powerful LED which, combined with a matched driver, is capable of operating up to 50,000 hours on a single CR2032 battery. The optics of the collimator have a multi-layer anti-reflective coating which guarantees good light transmission, delivering a bright and clear image to the user's eyes. It has no parallax error and provides unlimited distance from the eye. This allows comfortable aiming in all types of long guns.

Shake Awake system

Shake Awake is a proprietary Holosun system that directly affects the collimator's long-term operation. After a pre-programmed operating time, the sight goes into sleep mode to save energy. A slight movement of the weapon on which it is mounted is required to wake it up. The collimator will automatically turn on and allow further aiming.

Construction of the sight

The housing is made of 6061-T6 aluminum subjected to the anodization process, thanks to which it gains greater chemical and mechanical resistance. The control system and the diode can withstand strong shocks and recoil of up to 1000 G. The sight is also waterproof, meeting the IP67 standard. The collimator has a low weight and fits either a Picatinny or Weaver rail. in 2 brightness modes it works with night vision. The battery is mounted on a sliding tray. This is quite a convenience as it allows changing the battery without removing the collimator from the weapon.
