Holosun HS510C HUD Solar Powered Circle Dot Sight

Purchased the 510c simply based off my prior experience with Holosun optics, my love for the Eotech reticle and Eotech open face style sight. The integrated QD mount is an added bonus, but the real key factors that make this sight great are the motion detected on feature, auto brightness (though tends to be on the dim side), which can be changed to manual brightness, battery life, 2 moa dot/60 moa circle/60 moa circle w 2 moa dot reticle choices and the titanium hood that goes over the optic itself to protect it from use. The auto on feature should have been integrated in eotechs years ago, and at $250, this is my fav cqb optic right now and will be going on many of my rifles going forward.

Amazing optic. Way better than an EOTech in my opinion.
I mounted on my Arsenal AK-47. Was easy to zero and held zero through first 100 rounds. Love the reticle option and light weight. Love the automatic mode.

Very nice fit and finish. Clear and bright. Fits rail perfectly. Easily adjustable. Nice packaging.

The 510C is IMO the best red dot optic on the market today! The increased field of view is awesome! The quality of Holosun is just icing on the cake!

As always; I’m amazed on how fast PA delivers and how great their prices are. Very happy with all my transactions so far. Never had an issue and they send stuff in a matter of days (I’m located on the east coast). This Holosun sight is amazingly clear and unlike the Eotech it is sharp and crisp. Keep in mind that this sight is projecting the image which it's different than the holographic design on Eotechs but I think this is much better. Pretty sturdy and can take a hit. Don’t care for the auto-mode as it blinks when changing light settings but with the good old manual operation you cannot beat this puppy!

I have purchased different red dot systems for several weapons, and I have found this particular model to be the easiest for me to see through. Yes, unfortunately I have an older set of eyes that require guidance, and the reticle that this unit provides places my focus on target through a co-witnessed sighting system. The only drawback to this current setup is that the ammo to truly enjoy it simply costs to much be able to truly sight it in. But I definitely believe that in these trying times it is really ballparking the shot right now.

Great price, excellent service on a reliable product, using on a AKP, holds zero and very durable

This is my second HS510C. I have had my other one for 1.5 years and love it! So far I have had great luck with Holosun, I have several other sights also and all are great.

The circle dot reticle is clear with minimal to zero blooming, great battery life, smaller foot print than an eotech, no noticed parallax, and this is my second one. I have eotech, aimpoint, and trijicon red dots the 510C is my favorite. 1 on my home defense and my SHTF.

This is my second Holosun HS510C. It's impossible to give the optic less than 5 stars. It strikes the perfect balance with quality, features and price. My favorite feature is the shake to wake technology that automatically turns your dot on at the slightest movement so you're never caught unprepared. The huge sight picture with 3 different dot options makes this a joy to go target shooting with. As always, Primary Arms is my go to for anything firearms related.

I really wanted an Eotech because of the name and reputation, but after using my first Holosun 510, and reading reviews of how this is not only comprable but in some ways better, Holosun HS510C is the best option.
