Magpul new plastic prosI have an PA micro on my Fleming kit, a Cmore on the MK 2 and an Eotech with MI flip up irons on the 31C and like them all. I think the more field of view the better, because for me anything past 2 or 3 rounds I am tracking the impacts more than watching the sights.
Same hereI have Scorpion EVO sights on a couple of my Lage uppers. I'm very happy with them.
