The guns were scrapped. Attachments are still a thing. Here's a link to a recently-released GamerEscape interview. Important stuff is here:
"The basic concept for the attachments that the Machinist can use is that they will augment your DPS, and they are continuing to tweak it, but for example when you are attaching the attachment you will not be able to move. So while your DPS may increase, for example, you will be immobile. The turret accessories will be called out as a ground target and can be used to buff allies or debuff enemies depending on the situation. Another action specific to the Machinist will be a “reload” and “quick reload” action – but Yoshida assured us Machinist does not actually consume any type of ammunition in connection with this."
