HS403B is a 20 mm micro sight designed for rifle and carbine applications. HS403B features Holosuns Red Super LED with 50k hour battery life, 10 daylight and 2 night vision compatible reticle intensity settings. Its housing is made from 6061 aluminum and includes both a lower 1/3 co-witness mount (1.63) and a low mount (.75) for low-comb height rifle applications. Additional features include Shake Awake technology, digital buttons for setting changes, rubber lens covers, and a side-mounted battery tray for the 2032 battery. HS403B is a versatile sight for users of all levels. Shake Awake Technology is a standard feature on all current model Holosun optics and serves to extend battery life by deactivating the optics LED while not in use. A highly sensitive motion sensor works to detect motion keeping the LED powered on during use. This allows for duty or concealed carry with seamless operation throughout your day or shift. At the end of your day or shift when your firearm is stored, the motion sensor will detect a motionlessness state and after 10 minutes (default setting) Shake Awake Technology powers the LED off until motion is again detected. Shake Awake offers settings from 10 minutes to 12 hours depending on the model and can be deactivated altogether if preferred. The slightest touch of the optic instantly reactivates the LED so your Holosun optic is ready when needed. IP67 Waterproof.
