Walkthrough
Borderlands 2 Arms Dealing is a timed mission, so its a good idea to prepare a vehicle outside the town of Overlook before doing anything else. Then we can go to the first mailbox thats exactly near the Catch-a-Ride system.
During this mission we have to open five mailboxes and collect the arms that are inside them. As soon as we pick the first arm, the mission timer starts, and we have to get inside our vehicle. Next we must go as fast as we can to the southern part of the Highlands region to get the other four.
Until we learn the exact spots of the mailboxes, this mission may be a bit difficult. If we run out of time too often, we can try a trick: we park a vehicle near the highest location of the three mailboxes in south-eastern region, and we reactivate the mission from Overlooks bounty board using another vehicle. Then, after we get the first mailbox we use the Catch-a-Ride system to teleport to our first vehicle. That should give us a good time advantage.
After we have all five arms we need to deliver them to Zeds mail box thats exactly near the bounty board in Overlook. Next, we use the bounty board to complete Borderlands 2 Arms Dealing and we continue to play other mission in the Highlands area.
