Re: C96 export ?

It's pretty unlikely. It's a dev-only weapon. There was only one case when one of those was made available for everyone (Colt S-Tac in BF3), and it was announced in advance. As BF1 is basically at the end of the cycle and not a single word has been said about it, I would not expect DICE to release either the C96 Export or Howdah Sweeper.
