Most Helpful Positive Review Great Optics Package
The red dot and magnifier match up perfectly. Great clarity on the magnifier. I was worried after reading reviews that magnifier can get bumped out of position. I found the magnifier hold its position well, and doesn't move unless you want it to. So glad I went with this package instead of buying bo...

Most Helpful Negative Review Awaiting exchange
This sight is all I will ever need with the 3x magnifier included, additional battery tray, QD mounts and lower 1/3rd risers for both the sight and magnifier. UNFORTUNATELY, mine was defective and displayed an overlapped, or double, sight picture. I am awaiting a replacement unit now, will update th...

Holosun red dot

by Noname, Verified Owner from FL, United States Written on June 1, 2025
Great price and awesome quality. Shake awake feature is awesome. You dont have to shake it. Just pick up your rifle and aim. It'll be on when you look thru the reticle. Crisp red dot. Awesome eye relief.. works without a battery. Thats amazing. Charges while you use. Super strong and durable. Will be buying more for my future builds. Love it.
Pros:
  • Shake awake
  • Solar Charging
  • Night mode is great. No glare and crisp view
Cons:
  • None
Best Used for:
  • Rifles

Amazing Value

by chickens, Verified Owner from TN, United States Written on May 27, 2025
Compared to any EoTech, these are an amazing price to performance ration.
When including the received OP Bucks, you will not find a better optic for $400. There is the argument that some may like this more than a Holo. Great optic, will put on more rifles.

Fantastic Optic Setup

by Crabby, Verified Owner from NC, United States Written on April 29, 2025
This optic & magnifier work seamlessly together. The HS510C has several features & settings, good build quality, good fit & finish, large field of view & easy adjustments. The 3x magnifier integrates perfectly & focuses the reticle nicely with decent eye relief. I recommend using the included risers. Only issue I've had is my astigmatism - you will see double thru this sight unless you have corrected lenses.

holosun rds

by taco Tuesday, Verified Owner from MI, United States Written on April 11, 2025
It is a solid option for a rifle. Easy instal, simple zero. The glass is clear enough and the flip up is solid. For an option under 600 per optic you can’t beat it.
Pros:
  • Price
  • Build quality
Cons:
  • china

Holosun HS510C & HM3X Magnifier Combo – The Best Bang for Your Buck!

by Ev0, Verified Owner from FL, United States Written on March 31, 2025
If you’re looking for a high-quality, battle-ready optic setup without breaking the bank, the Holosun HS510C Circle Dot Sight paired with the HM3X Magnifier is hands-down one of the best investments you can make. Whether you’re running drills at the range, using it for duty, or just want a rock-solid setup for home defense, this combo delivers outstanding performance, clarity, and reliability at a fraction of the cost of other high-end optics.

HS510C Red Dot – Crystal Clear & Rock Solid

The HS510C is an absolute beast when it comes to performance. It offers a large, wide-open sight picture, making target acquisition lightning-fast. The multi-reticle system is a huge advantage—you can switch between a 2 MOA dot, a 65 MOA circle, or both depending on your shooting needs. Solar power backup means you’ll never be left in the dark, and the battery life is insane (up to 50,000 hours on a single CR2032). It’s also built like a tank—shockproof, waterproof, and ready for anything.

HM3X Magnifier – The Perfect Companion

A red dot is fantastic up close, but when you need to stretch your shots out, the HM3X 3x magnifier steps in beautifully. It provides a crystal-clear image, great eye relief, and a super smooth flip-to-side mechanism that locks into place when you need it. Unlike other magnifiers that cost twice as much, the HM3X delivers premium performance without the premium price.

Why This Combo is a No-Brainer
• Unbeatable Value – Comparable setups from other brands cost hund...
