for a dedicated .22lr suppressor, I'd recommend a user serviceable one, (I.E. one that can be taken apart and cleaned) due to all the crud that .22lr leaves behind, and since the bullets are usually just copper washed/plated, rather than a copper jacket like a centerfire round. If you get one that does not have any aluminum in its construction, you can soak it in the various homebrew solutions that can be found on the net to dissolve most of the crud.
YHM Mite is $200 @ masgunworks.com , and $199 @ major-malfunction:comCan you name any mfg./post links? Fair price?
I've been shooting .22LR through my .223 can with great results although everyone thinks I'm crazy for doing it.
