No. The seers have been banned. I don't think anyone thinks they're not machine gun parts. What's been going on is the ATF has been going after a variety of methods of circumventing the concept--means of using the recoil to "pull" the trigger without the operator actually pulling it. The result sure acts like a machine gun, albeit an unreliable and inaccurate one. The problem is that it's simply too easy to do, they are fighting a hopeless battle. My understanding is the same problem applies to silencers--plenty of filters out there that just happen to be of the right size to function as silencers. And there isn't even any reason for the rules against silencers. They aren't like Hollywood, it's still loud but below the threshold of hearing damage.
