Holosun Red Dot HS403B is a compact enclosed red dot sight with the Shake Awake system and red illumination of the reticle. This model was designed for rifles and carbines and can be used in the most demanding conditions.
The housing is made of highly durable 6061-T6 aluminium alloy. The overall weight with the high mount is only 124 g. You can attach to the standard Picatinny or Weaver rail on your weapon. The package contains two mounts in total. The 1/3 co-witness mount is designed for carbines and the low mount is ideal for rifles.
The lenses are multi-coated and have anti-reflective surfaces, ensuring a good light transmission and clear and precise picture. The 2 MOA dot allows for a fast target acquisition.
This model is powered by a single CR2032 battery, which should give you up to 50 000 hours of battery life while using brightness level 6. You can choose from 12 different brightness presets (10 levels for daylight and 2 night vision compatible levels).
The inner electronics and the LED are resistant to impacts, recoils and unfavorable weather conditions. The Shake Awake system will automatically turn off the LED when it doesn’t detect any movement and move to sleep mode. All you need to do to turn it on again is to make a move with your weapon. It is possible to set the time, after which the sleep mode activates itself.
