The Holosun HS403C Red is a solar and battery powered 20mm micro sight designed for rifle and carbine applications. HS403C features Holosun’s 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.

HS403C is unique in that it is always on and ready. If there is ambient light available it will power the HS403C even without a battery. Additional features include digital buttons for setting changes, rubber lens covers, and a side-mounted battery tray for the 2032 battery. HS403C is a versatile sight for users of all levels.

It features a crisp red 2MOA dot. The highly efficient light emitting diodes and solar cells allow Holosun solar optics to run without a battery in many lighting conditions. Additionally, the CR2032 battery lasts up to 5-years. The HS403C is compatible with industry standard mounting solutions (Aimpoint Micro footprint).

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.
