I just got a ql 5 desert vulture reward from a trader mission. It was in a box that said desert vulture parts I think.
Most of the time I haven't been to impressed with the stuff but now that I look at it, I got every weapon I wanted from a trader. I got a compound crossbow, baseball bat, and the desert vulture. I bought the parts I needed to make my pistols and could have made bows except I got the compound crossbow very early so I haven't made any.
I'm not so sure the traders have a problem anymore. It's a perception problem for sure.
This is also the sort of thing that the very next game I play might leave me very disappointed with the traders.
