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.
Multiple Reticle System (M.R.S.)
M.R.S. gives the user the flexibility to use their optic as they need it. Units with this feature allow the user to turn on or off certain sections of the reticle giving the ability to have the ideal reticle for the job at hand. If you need a precise shot, you can run the 2MOA dot only. You need a reticle for fast target acquisition, just turn on an additional 65MOA ring with the push of a button! The best part....no need to rezero your optic when switching between reticle options!
