Great magnifier! - Meprolight MMX3 3x18mm Micro Magnifier w/ Quick Flip, QD Picatinny

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.
