True - the Daystate Airstream is the only one I know of. The ones I have made have worked well - back vented ones in particular give good down range suppression but do sound a bit louder than some people expect behind the muzzle -> air+energy = noise directed back towards the shooter.
It is a kind of hobby experimenting with what can be done.
