Vendor wise, the top guns would probably be Hung Jury, Not Like the Others, The Villainy, Hawksaw, and the New Monarchy AR. The Vanity from FWC is also a great weapon, but it has a chance to crash your game. If you get a good roll on something else, try it out. I have a Last Extremity with Triple Tap, Hand-laid Stock, and Grenadier. Great for the raid dues to how hard it hits and how quick it recharges my grenade due to all of the adds.
