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 reticle w/ 3x magnifier (HS510C)

by Ty, Verified Owner from TX, United States Written on February 10, 2026
From shipping to packaging everything was legit and well organized. Shipping only took a week. The box the sight came in was a sturdy travel size case that will not break if u were to drop it. The red dot and magnifier it self are made of great quality metal and titanium. You can tell the product is made well by the weight of product itself. No cheap materials or cheapy brackets. I did much research before buying a Holosun, it ended up being the perfect purchase instead of having to spend a $1000 on a single eotech. For the price and quality you get the best bang for buck. I highly recommend trying out a Holosun. Only downside to MY optic (HS510C) is that it is an open reflex from the rear of the sight. Other than that, its legit. Great window size as well.
Pros:
  • Price
  • Shipped and arrived fast
  • packaging is very secure and clean for shipping. Fit and finish is excellent. You can tell this was made by someone that knows their way around a machine shop! Functions are all smooth as glass!!
  • appealing to the eye
  • Qualify of design, machining and materials
Cons:
  • Open reflex
Would recommend: Yes

Good option other than Eotech

by CatfishCraig, Verified Owner from OH, United States Written on January 15, 2026
I love this thing. It is light weight and easy to pick up with the eye. Has very good brightness and the shaped awake feature is awesome. Easy to put on or takeoff the rail. Would definitely buy again.

Buy Once, Cry Once: Good Quality

by Commander Iceman, Verified Owner from MI, United States Written on November 18, 2025
While I haven't taken this setup to the range per se, I like what I see in terms of how clearly I can see an object at a distance. Using my range finder, I was able to easily see targets out to 315 yards using the 3X magnifier. The red dot sight is decent, in that it has three different sight pictures (dot, circle, dot+circle) and one can easily transition from one site picture to one of their choice.I believe it has eight different levels of brightness so as to accommodate daytime, night, or indoor usage. The swivel on the magnifier is tight and robust enough where it won't accidentally swing out of position unless deliberately pushed upon. I also like the hardcase it comes in and the rubber lense caps for the magnifier. True enough, this setup adds a bit of weight to one's rifle but the trade-off is definitely worth it because of the versatility you gain being able to engage targets up close or at a distance
Pros:
  • Tactical versatility
Cons:
  • price
Best Used for:
  • close quarters
  • Close Quarters Battle - CQB
  • Close ,mid and intermediate ranges.
  • Close quarters, mid range

Good Stuff

by Liberalwithagun, Verified Owner from CO, United States Written on October 26, 2025
Works well on the CMMG Banshee 300BLK. Nice to have the 3x magnifier for longer shots. Only thing I don't like is the eye relief for the magnifier, but not the end of the world since you can quick disconnect or flip out of the way for red dot use only.
