The Suros ones from the armsday orders are the only ones with full auto in their perk pool that I have seen. Haven't actually seen one with it yet but it's pretty high on my to get list. There are two of them. One is nl shadow style fire rate and the other is mid tier. I will place an order for these every time they are available. Sadly, it's one of 15 perks that can roll on the middle node.
