Holosun Hs510c Four Month Review
Holosun 510C Review: Verdict, it’s a winner.
I’ve had the Holosun HS510C for a little over 4 months now and it’s not quite what I expected. It’s better. So much better.
Traditionally I have used the same Eotech 512 or XPS2 that I sank my money into years ago when testing a new carbine. They are both great, solid performers and tough as tanks.
However, when I was working on the 9mm SBR build, I was really intrigued by the early photos I had seen of the Holosun 510 and decided that would make a good addition to the build and I could, if nothing else, get a review out of it.
Quickly below are some of the technicals from Holosun themselves.

With all of that out of the way, let’s get to the review.
To begin, the 510C is built to take abuse. The upper assembly is shrouded in a titanium cover which provides a tough-as-hell skin for the glass and internals. It will take more abuse than most of us will ever throw at the unit.
The only parts that aren’t covered by the shroud are the solar cell panel and the LED projector. It is after all a reflex sight, so yes, there is a projector sending the selected image onto the glass for the operator to see. There are three options of projection to choose from, Circle, Circle Dot and Dot only. All of them are crystal clear and the two lowest settings will work with night vision if needed.
The solar panel is a great feature for helping to get the most out of your battery. As long as there is any source of light available you will have an illuminated reticle available. Should your battery run out, the solar panel it a very welcome feature. One thing to note is that you have to have a battery installed for the solar panel to work. It completes the circuit. If your battery is dead but installed, you’re still good to go.
The 510C has a crisp 2MOA Dot and a 65 MOA Circle. Holding down the Minus (-) button for three seconds will cycle through the different reticle options. I have mine set on Dot only and right around medium brightness. This combination is what Holosun prefers to get the most out of battery life. I am very used to only having a red dot from the Black Spider Optics Red Dot I reviewed earlier and have just become used to it. The Circle/Dot is very reminiscent of the EOTechs.
Speaking of battery life, using the suggested settings from Holosun, a single CR2032 battery will net you 50,000 hours of battery life mostly due to Holosun’s ShakeAwake feature (see link above). This allows the operator to simply set the sight once to their liking and leave it on. It will automatically shut itself off, kind of like a sleep mode, after a period of inactivity. Next time you pick up your rifle it will turn itself back on to your previous settings.
The 510C comes with a quick detach mount that will perfectly co-witness with your BUIS. I have tried both Magpul Gen 2s and Magpul Pros and the co-witness is perfect. Of course there are windage and elevation adjustments to zero the sight on your gun.
After 4 months I have 700 rounds through the 9mm SBR and I have had zero issues with the 510C. It still holds zero perfectly. I’m still on the first battery. The buttons on the side still have positive tactile feedback and work as they should.
I would say, hands down, for the money, the 510C is the best option out there for a carbine reflex sight. This is not a paid review either. I did not receive this from any dealer nor Holosun. I bought this sight with my own money because, like I said, I wanted to try it and at bare minimum, get a review out of it. I know we all have to be careful where we put our dollars. Like you, I want my money to go to the best products my money can buy, at the best possible price.
If you need a new sight, put this at the top of your list to check out in person. You won’t be disappointed.
