He needs to provide the paperwork. It would be best to have a Dealer ship them for him, if he's not able to do so. That way he and you are both covered on all BATF Rules.
A lot depends on which State your shipping them from and which State you are shipping them too. I don't see a problem with you listing them on here for him, though.
Also, In dealing with states like CA, NY, MD, MA, NJ, CT, HI, and several others, there are many other legal issues to deal with as to what may be legally shipped there.
Just be sure you cover all your bases, dot all the i's and cross all the T's so to speak. Be sure to check ALL the rules & regulations on the BATF web sight, too. Don't just go on what someone told you they thought was legal to do.
