I have flip-up “iron” sights made by that brand on a couple of ARs. I’m very happy with them. I also recently got one of their red dots; I haven’t thoroughly tested it yet, but my initial impressions are great.
i got one of their flashlights and it works quite well. I also got a couple of their scopes, but haven’t really tested them on anything with much recoil yet.
