The HE403C-GR emerges as a compact 20mm micro sight engineered for rifle and carbine utility, blending solar and battery power capabilities seamlessly. Boasting Holosun's Green Super LED technology with a remarkable 50,000-hour battery life, this optic offers 10 daylight and 2 night vision compatible reticle intensity options. Crafted from durable 6061 aluminum, its design encompasses both a lower 1/3 co-witness mount (1.63 inch) and a low mount (.75 inch) for applications requiring a reduced comb height.
Distinguished by its perpetual readiness, the HE403C-GR remains operational whenever ambient light is present, even in the absence of a battery. Notable features include Shake Awake functionality, user-friendly digital controls for swift adjustments, protective rubber lens covers, and a side-mounted battery tray tailored for the 2032 battery. Versatile and accommodating users of all skill levels, the HE403C-GR stands as a flexible sighting solution.

Solar Failsafe

Solar Failsafe Technology is one of many innovations featured on solar-equipped Holosun optics. With Solar Failsafe, if your battery fails you always have a backup power source when natural or artificial light is available. Solar Failsafe is activated while in Auto Mode where reticle intensity is automatically adjusted based on the amount of light the solar cell receives. In brighter conditions you have a brighter reticle and in lower-light conditions the reticle will step down in intensity to match any lighting conditions. On models equipped with a super capacitor, it is possible to run the optic, indefinitely, in daytime and night conditions, by maintaining a charge through the Solar Failsafe System all without a battery.

Shake Awake

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.

Super LED

Holosun Super LED technology includes Red, Green, and our latest Gold Dot LEDs providing options that match various environments and personal preferences including red/green color blindness with our Gold Dot. Super LED technology provides a versatile range of reticle intensity settings from night vision-compatible to daylight bright. Holosun Super LEDs have ultra-efficient power usage creating battery like as high as 50,000 hours on certain models. Our Super Green LED is designed to match the wavelength of light that the human eye is most reactive to.

Multilayer Reflective Glass

Holosuns use of Grade 5 Titanium in certain Elite category optics and laser devices results in unparalleled strength and durability. Holosun Grade 5 Titanium has more than double the tensile strength and has five-times the fatigue strength of 7075 Aluminum. Grade 5 Titanium is also able to withstand the corrosiveness of seawater making Holosun Titanium model optics and lasers suitable for use in maritime environments.
