Interstate firearm transactions are federally regulated, so I think only a prohibition on ownership within the recipient's state would nix the transaction. Only those pistols listed as "assault pistols" by Maryland are prohibited in the state (except, I believe, by people who grandfathered them in.). Sales going out of Maryland, would depend on the legality of ownership in that state (and local jurisdiction).
Only if state B is adjoining Maryland:
Maryland: Residents of Maryland can purchase non-regulated (shotguns and
non-assault style rifles) long guns in the states of
Pennsylvania, Virginia, Delaware and West Virginia.
Residents of PA, VA, DE and WV can purchase non-regulated
long guns in Maryland.
