Most Helpful Positive Review Well-Built And Excellent Clarity
I picked this up, and I couldn't believe how excellent it was for the price point. Eye relief, believe it or not, was better than the G43. Pivot hinge works very well and is very sturdy. Glass clarity and brightness are excellent, and the QD mount works very well. I wish that they had more of a ...

Most Helpful Negative Review nice, but has design issues
I have a Meprolight M21 on one of my flattops. I wanted to add a 3x magnifier, so I purchased the MMX3 (brand consistency). It's a nice unit, but it has some quirks that are a bit annoying. First, with the M21 mounted as far forward on the pic rail as it will go, the flattop is one slot too short...

This weighs so little that I barely notice it. I use this on my Rattler, and it works great.

Great Magnifier!

by JT, Verified Owner from KS, United States Written on July 23, 2024
Of the many optics I have, I've got a few magnifiers as well to compare this against. Meprolight makes some great products, such as the Tru-Vision tactical red-dot. This magnifier seems well built and is good sized - not too long or too heavy for its capability. The eyebox is good and the magnifier has been able to dial in through adjustment to pair-up and work very well with a 1X prism optic, and two different red-dot sights at differing heights. The glass is clear, with no significant annoying colorization. It has mounted up solidly, with the flip mechanism working just as it should. The Quick-Detach lever can be oriented either direction, and the "flip-direction" can be set for left or right. A bonus is the removable rubberized cover/sleeve that can change the general color to FDE or black as you prefer. The packaging and misc. accessories that come with it are also very nice and of good quality. All-in-all it's a solid product for the price, and I'll likely be buying another one or two of these.
Pros:
  • Clarity
  • features
  • solid
  • Value & Quality
Cons:
  • None
Best Used for:
  • red dot
  • 1X prism
