The Best Optic Solution for Airsoft

Typically, optics used in Airsoft are cheap overseas clones of real firearm specific optics. This is due to the standards of a real steel optic being overkill for Airsoft purposes and a steep investment for Airsofters to make. Fortunately, Holosun has a line of products that not only have the durability and standards real firearm optics possess, but also at an exceptional value that makes it perfect for Airsoft customers as well.

The Official Optic of Umbrella Armory

If you are looking for an optic solution that can stay on target, has an incredible sight picture, and can last you a lifetime; Holosun is the best on the market.

The HS403C is a solar version of the successful HS403A. Our highly efficient light emitting diodes and solar panels allow Holosun solar optics to run without a battery in many lighting conditions. Additionally, the back-up battery lasts up to 5-years. The HS403C is compatible with standard mounts.

Solar Failsafe™: Holosun was the first to innovate the ability to run an electronic optic solely on the power of light! Our units equipped with this feature give you the confidence that in the instance that you find your battery has failed, you still can have a fully functional optic provided you have sufficient ambient light. It does not matter whether the light is natural or artificial in origin. Furthermore, the solar array also acts like a light sensor allowing the unit to automatically adjust the brightness to compensate for its surroundings.
