Yup. One for a 223 will work for a 22. I will swap to my Ciener 22LR conversion in my AR and use an M4-2000. There are others that are lighter and don't have the quick connect which would be cool but the .223 cans bring what I think is too much weight to a rimfire. The weight may not bother you though.
I'd go to
www.advanced-armament.com or
www.gem-tech.com to start looking. Tactical Solutions makes them...heck a lot of people make them. I never tried to find one for dual duty .223 to 22LR. I like the purpose build rimfire supressors because they are light...like AAC Pilot for the .22LR....but prefer a model that can be broken down and cleaned.
Bryon who owns Major Malfunction is a great guy and has a nice website..I got a 45 EVO can from him.
Tactical Solution is supposed to be coming out with one of their lightweight 22LR barrels integrally suppresed and that can be cleaned...that I would really like to have. The AAC Cloak is integrally suppressed but is heavy.
Also take a look at
http://sandhsuppressors.com/ for some really good integral supressors...check out the Ruger M77 in 44 mag that I will attest is 1/2 as loud as a pellet gun when using subsonic ammo.
And yes, as above, I have used my 45 can for my 9MM's.
