You've got some serious clairvoyance going on @Medusa. How did you manage to PM me about this very thing an hour ago?
I'm pasting some of what we talked about here:
Holosun stole IP from Aimpoint and EOTech, and make some good optics. QC isn’t as good, but they replace it if needed. For an Aimpoint type optic, Holosun is a good choice (if you're into supporting industrial espionage and buying Chinesium stuff). For a true holosight, my guess is that L3 (EOTech) still has the solid edge. They are a massive defense contractor with lots of smart engineers.
