I am new to silencers, have made two and have a few forms still pending but have learned lots in the last few years. 12 states do not allow unlicensed civilians to possess silencers, the rest all allow possession with some prohibiting ownership unless there are registered (duh). TX bans possession but registration is an affirmative defense to prosecution.
The best place to start to learn is the ATF homepage.
