In Comi-fornia it's impossible to own a suppressor. However my wife and I were invited to a cop demonstration by Surfire suppressors. I asked the guy who what states are able to buy suppressors. He was saying pretty much any state with the exception of CA and NY. I also noticed a few things when using these on the AR. - The recoil was that of a .22 - Because of that i could keep a picture of the target in my scope and followup shots were much faster, from standing position. - The noise was quiet enough to leave your hearing off, but still loud enough to be heard from quite a distance away. Probably just quieter than a .22 - The noise sounded exactly like a nail gun. (we were shooting 22 grain) They are pretty cool and wish I could have one. Even if they were legal in CA, there's no way I'm plunking $1700 bones! Pic of wife at the range: I shot the one on the table the 'mini' size..
