Holosun 512 Features

Solar Failsafe
Holosun was the first to innovate the ability to run an electronic optic solely on the power of light! Our Holosun 512c micro solar red dot sights 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.

Shake Awake
Another great piece of technology created by Holosun is Shake Awake. This great feature allows an optic to automatically go to sleep when the unit has not detected any type of movement or vibration in a specific amount of time that is programmable by the operator. However, once the unit senses movement, it will automatically turn itself on and recall the last brightness that was used. This great feature helps promote battery life further and insures the unit is on and ready when you need it!

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 32MOA ring with the push of a button! The best part….no need to rezero your optic when switching between reticle options!
