I have a Huxwrx RAD 22, I wanted a few more 22 cans when wait times disappeared and that was all Mile High had. I wasn't dying to have one for any of it's features, it's just what was sitting there and it was cheap so I gave it a go.
Really happy with it, it's quiet, has less first round pop than my Sparrow, and seems to stay much cleaner in a given firing cycle between a Tacsol 10-22, Tikka T1X, and a Volquartsen pistol. I cannot explain this because the vents aren't dirty at the front so it isn't like the fouling is flying out of it, but I'm not looking a gift horse in the mouth. I'd buy another one, but there are a million 22 cans out there that are good.
I still shoot one of the original TBAC 22 cans that you can't even disassemble and I love it too. I can't say there are distinct advantages to the Huxwrx but it seems to be as good as most of the other decent cans.
