I mis-posted the name, Burris calls it the "Fast-Sight", but I still haven't found one. To mount on the slide of an auto, as Burris claims theirs can, it would have to be very tough and I doubt any 80 buck Chinese clone would be up to that sort of abuse.
When I lost the hood to my Optima I got a new one from Jpoint, $20 for a bit of plastic. Anyhow, I think these tubeless red dots will replace the tube sights since they do exactly the same thing with a fraction of the weight and bulk. There are still a few bugs to be ironed out but I do hope Burris may have gotten a step closer in their new version.
