FX Question

I sent AOA an email some time ago and never got a reply so maybe someone here can help.

I'm told that the new FX Royale 500s are coming with a carbon fiber bottle, ( which I know the are ) and a regulator. I asked if the regulator was coming already installed from FX or if AOA was putting it in and never got a reply. Does anyone know which is the case, and if so, what regulator is being used ?
