The HS407C X2 is an open reflex optical sight designed for full-sized pistol and shotgun applications. The HS407C X2 improves on previous versions by adding Lock Mode which was first introduced in our 2018 LEM pistol optic models. Lock Mode, when activated, locks the buttons preventing inadvertent setting changes.

Additional features include Holosun’s Red Super LED with up to 50k hour battery life, Solar Failsafe, precision 2MOA dot, and Shake Awake. The durable housing is made from 7075 Aluminum, uses an industry standard footprint, and houses the 1632 battery in a side-mounted tray for easy replacement when needed.

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.
