The idea of bringing cans back over the muzzle has always been intriguing, but most reflex designs seem to demonstrate that going back is about half as effective as forward length at best. And I still feel that more than 2"-2.5" worth of chamber is just adding weight and limiting host options without any real benefit.
One of the biggest problems with reflex chambers is getting any meaningful amount of gas to change direction and fill the chamber before the bullet has time to get out. Simple chamber designs blasting pressure against the inside of the tube don't seem to do this very effectively, and a lot of reflex designs, especially older ones with more suppressor rearward than forward, are not hearing safe at all.
Without giving up too much detail and risking getting ripped off by other manufacturers, let's just say I came up with a design that seems to make the reflex chamber a more useful space. I call this can the Gyrex, and it is showing promise, although I won't have hard dB figures to compare with others for a little while yet. It is 1.5" diameter, 9" overall, but only extends 6-3/4" past the muzzle. The prototype came in at 15.9 ounces, although I could shed a little bit for a lighter duty hunting version that is not full auto rated. This particular one will go over a barrel that is .730" or smaller 2.25" back from the muzzle. It is not two point attachment; it's a direct thread muzzle only attachment, the reflex chamber fully contained in the can.
Please excuse the use of a muddy girl camo .243; wife wanted to shoot, and I just didn't feel like dragging any more weapons out, so I used hers to demo!
Still more testing and refinement to do, but I feel this one is very much a worthwhile pursuit. Will probably have a couple different versions of it, one that is a dedicated direct thread, and one which uses removable inner chamber wall/muzzle interface pieces. The latter will be necessarily heavier and more complex, of course, carrying a higher price tag, but will make it a more flexible can that behaves as anything from a normal 9" long muzzle-forward can to the configuration that makes use the full 2.25" of reflex chamber.
