The authentics are made by titanium-mods.com, but I have 2 clones, of the originals; broke down and bought one of the authentic Achilles II's when this FDA bullshit was announced back in the spring, but I don't like it NEARLY as well as the originals -- too airy. I managed to address that problem by inserting a 12ga blunt needle in the inner airhole and cutting it off with a dremel wheel, but unfortunately, unlike the originals, the bastard LEAKS! I replaced the o-ring at the point where the tank part screws onto the base, but it didn't help, so there must be a problem with the threads there.
I also hate the new AFC control; much preferred the originals' hex-key adjustment on the bottom, like kayfuns had. And I have to wonder if that new-fangled AFC adjustment ring might be part of the reason for the leaking.

Yeah, that's Bashik. They make great stuff, but titanium is a REALLY dry thread. VERY easy to cross thread, bind, whatever. I have some mods like that. LOVE the weight, though. I wish I could help, but I'm not familiar with the achilles.
