I have a SWR Spectre suppressor. This can is rated for .17, .22lr and 5.7x28mm. So far I've shot it on my FN Five-seveN and Walther P-22 pistols, and on my Sig 522 rifle. This is a great piece, it comes with a break-down tool and (optional) baffle push tool to tear it down and clean it. I really like this can. <thumbsup> http://www.swrmfg.com/Rim-Fire-Suppressors/swr-spectre.html
