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...

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.

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.

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.
