I got my first 22cal high velocity center fire rifle silencer from rebel silencers out of El paso, Tx. It was a $200 can when I bought mine off gun broker. Rebel has it listed for $350 now, nearly a year later. Still might be able to get them for around 200 if your nfa dealer isn't a gouger. I like it. Makes shooting an carbine ar15 bearable. It deadens the blast to around 22wmr 17hmr from a rifle level. It's not hearing safe bur close. It's super easy to clean, no special tools needed.
