When it comes to Rifle silencers.. there's AAC, KAC, and Surefire in the mainstream. If you're talking PISTOL and RIMFIRE cans, the field opens up a bit since those cans aren't exposed to as intense amounts of heat and pressure.
I personally won't buy Surefire since they originally did NOT offer their cans to civilians. And I've never seen a KAC in real life. So I've got two AAC rifle cans.
