Unproven, but awesome so far - Holosun HS503R 1x20mm 20 MOA Red Dot Sight

Glass has better optical quality than Aimpoint T2. Circle dot reticle is crisper than Eotech in a much smaller and lighter package. More than bright enough for any situation on this planet. The mount sucks. The optic is compatible with all aimpoint micro mounts, but center line is 3-4mm higher than aimpoint. So if you're trying to pair it up with a magnifier, you have to get an adjustable mount. Most absolute cowitness mounts will put this optic near lower 1/3 witness height. I do wish it had clear flip caps like aimpoint. For causal recreational use I prefer this to my aimpoints, eotechs, and trijicons. However, unlike those optics, this holosun has not been taken to war and had it's durability proven in battle. That's kind of a big deal and only time will tell.
