I have a Silencerco Spectre II and am very happy with it. I shoot it mostly on a Walther P22 and a Ruger 10/22. If I was going to get another rimfire can I'd probably get a ZAI Voodoo. They are made near me in Nebraska. Pretty similar to the Spectre, is mag rated, and is a little cheaper. The guys who make them run Silencer HQ, where I've gotten all of my suppressors from. Great guys with top notch service.
