So I finished the Lt Bantam manhunt at Potomac. I shot him before he dropped down in the main area. He dropped a Exotic and other gear.
But I can't pick it up because it's out of bounds and out of reach. There's no jump points at that locations where i killed Lt Bantam. I don't know if he drops a exotics all the time, but make sure you kill him after he drops down in the main area...You are warned!!
