Solid Reflex Sight
Pretty impressed with this sight.
Good sized window and while I mostly run the circle dot reticle, I like having the option to switch to just a dot reticle.
Controls are on the side and easy to use. Opposing side battery tray means you don't have to remove the optic to change the battery (not that you will need to be changing this battery often).
Green reticle is crisp and still visible in all but the brightest direct sunlight.
Indoors, upon opening the box, I noticed some glare/reflection when not looking directly through the optic. Seemed like an effect of the coatings. But once on the range, indoors or outdoors, it never was an issue or even really noticed.
The QD mount design isn't my favorite but it held up to my abuse without any issues.
Holosun is making some great advancements in the red dot market.

First Impressions
Just received my HS510c in the mail after a 5 month wait, well worth it. The sight itself seems to be well built and fits snug on my upper receiver rail. It is important to note this is a REFLEX not a HOLOGRAPHIC sight. Holosun did their homework and managed to isolate the specific wavelength of the...

Too Complicated
This sight APPEARS to be well made, but I didn't keep it long enough to find out. Too many "bells and whistles". I had to keep referring back to the owners manual to change from manual to automatic. Never got around to trying to change reticle pattern. Couldn't even begin to imagine how I would reme...

Great product highly recommended
My 510c arrived on time and was very easy to set up on my 45 pcc. With minimal adjustments it zero at 50 yards , almost perfect out of the box. Also very impressed with the ease of target acquisition and field of view from this optic. Highly recommend

Review of my 510c
I like the shack awake option, it was my understanding it had auto dark and light but I have not figured it out yet. The color tan matched my tan rifle. Came with a battery. No sticker… when you spend this much money. It’s nice to get some stickers as I like to put them on my coolers and freezers and such.
Would recommend: Yes

Man this is my first Holoson I’ve had ecotec an love them but for the price this is by far right there with it
Would recommend: Yes
My second one
I bought one of these sights a few years ago for my Ruger PC Carbine and like it a lot. The green reticle/dot is easy to acquire and crisp looking making hitting the target simple. It mounts quickly to the rail and was simple to zero. I'm planning another rifle this year and ordering another Holosun 510-C green dot before tariffs jacked up the price was an easy decision. For the money these are hard to beat.
Would recommend: Yes
Holosun 510c
Great optic for carbine platforms. The multiple options for the sighting image are a plus. Could be a little bulky for some pistol based platforms, but overall great quality at a decent price point.
Pros:
- Sturdy
- wide field of view
Cons:
- No cover included
Would recommend: Yes
