Holosun 510c

The Holosun 510C Reflex Sight has an open frame for a wide sight picture. Always on, it is powered by solar cell under normal usage, and a back-up battery to supplement power requirements in low light conditions. The reticle can be switched between a 65 MOA circle with 2 MOA dot, or a 2 MOA dot only at the push of a button. Better yet, the same LED projects both reticles, so no re-zeroing is necessary. The Holosun HS510c is extremely durable and will not disappoint!

Holosun 510c Features

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.

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 1o minute time period. 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.)

The Holosun HS510c Elite 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 re-zero your optic when switching between reticle options!

    This is a super nice optic. I have severe astigmatism and the 65 MOA ring is crystal clear and the 2 MOA dot has only the slightest starburst. Compared to a holosun which was practically unusable for me, this is amazing. I also thought it came with an extra battery because it turned on and stayed on for like 10 minutes. Turns out the solar cell is pretty good too!

    Throw some locktite on the mounting screws and fire away.

    Bunch of us compared several different red/ green dot style sights. Big names, big bucks and mine. Well the big buck boys hardly said a thing after we all looked down the barrel of 9 sited rifles. Dollar for dollar this Holosun 510c stood up to them all except one. Big buck Trigicon had a following in there but this thing came out 2nd. I can get three of these for less money of the Trigicon. I am very happy with this thing. ( my second) solid well made, quality throughout. And up to 50000 hour battery life? That top dollar mr T couldn’t say that at all. Thanks #kenziesoptics for still having it in stock.

    Basically an EOTech for ~ half the price. Awesome quality optic!

    Bought this to compare against a Eotech 552/512. Not going to lie, I’m VERY impressed with this sight! I wasn’t expecting much but this far exceeding my expectations. I would definitely recommend this if your looking for a good holographic sight!!
