The better meprolight magnifier - Meprolight MEPRO MX3-T Magnifier with Tactical Flap Mount

I ordered both this and the push-button versions of the Mepro magnifier and much preferred this one from the free play perspective. This one has almost none. Overall the optics are not bad, but better suited for dot type reticle vs. triangle. This is because towards the center of the lens there is almost no distortion, but as you move away there is both distortion and some ghosting. Which is undfortunate because you aim with the tip of the triangle, not the center. I found myself always trying to adjust my eye level, hunting for the spot where the tip would look clean. Also in my experience this magnifier worked much better with the taller Mepro Mor Pro than the more compact M21. While both are usable, the lower reticle position on M21 forces you into a very tight cheek squeeze in order to see the aiming point, which is not feasible for all situations. I much prefer the more relaxed chin position. Ultimately, while on paper the idea of a red dot sight with an option to magnify sounded attractive, I ended up going back to ACOG, which offered lightyears better optics in a less cumbersome package, while still supporting CQB aiming with both eyes open.
