I just hope that if the weapons are craftable, they give us a few more vendors.crimson caravan, and nellis vendors don't resupply.Alexander doesn't either.
People have mentioned someone in camp mccarran selling/buying items.The booth inside the airport concourse doesn't have anyone running it.Only can sell to the doctor.
The assassin squad killed a few traders.so I need somewhere to sell expensive items.
It cannot be that difficult to head over to the Fallout Wikia. The man you are looking for a Sergeant Daniel Contreras. You were in the right area at the concourse, but you are supposed to go down one of the hallways(actually I think it is the only hallway there) and follow it to a door. That Door leads to the Camp McCarran Supply shack. In it is Contreras. Contreras has about 1000 .308 Rifle rounds, and 150 each of armor piercing and anti personnel. He also has that many for 12.7 mm, and several boxes of 5mm surplus, and some assault Carbines. This is of course assuming you get there at an average level.
Now onto more important matters; the items are going to be put into vendor lists, but this leads me to wonder which ones, and whether this ensures that some of the vendors finally cycle their gear, as Alexander cycled his gear Once for me. This kind of aggravates me: How could you hear all of the news about this DLC and not hear that they will be in vendor lists?
