I did a search on this and came up empty. Anyone have one?
Are they worth a dam?

We mounted one on a AR-9 and I really like it. Easy to hit targets out to 100 yards with the 9mm. Easy to operate and change between reticles.

Search Holosun HS510C, or HE510C-GR for the green dot version. There are lots of them on GunPoker.

Like mine, Green, The shake awake feature is the real deal.

The reason I’m asking is I stumbled on one locally for a deal. Just curious as to quality.

I put one on my AR pistol with the quick detach mount . I think it cost $299 at my LGS . Very sharp and clear .

I wound up buying the one here. Seems like a pretty good value. They do have a bright/sharp dot.

I have one on an ar. So far it’s been solid no complaints.
