I have a Romeo 4H on my M&P AR 15-22, figured it was perfect for a toy. So far everything has worked as advertised and it’s held zero perfectly.

There is some confusion as to what it really is, Holosun, Primary Arms and Sigs all look very similar and all have about the same reviews, range toys that work fine and might not be a bad option on real use guns. FBI approved one of the Sigs for duty use. I don’t think I’d give up an Aimpoint for one but I like mine just fine.
