All I am going to do is ask you to look at the Tactical Innovation Quest suppressor.
Its an all stainless steel screw on suppressor, that can be disassembled by the user for cleaning - for the .22 RF cartridge.
Just look at it, read about it and decide for yourself if this is right for you.
Personally I own two - I LIKE them THAT MUCH.
At $399 retail, I don't think you can find a better "can". Note - I am in no way affiliated with the company, just a very satisfied user.

Lastly - whatever you do, do not get a "sealed" suppressor. In my opinion they are a waste of money. With the one caveat being - unless you don't plan on shooting it often. Trust me when I say you want a suppressor that can be user disassembled for cleaning.
