Unfortunately, they decided that B rank weapons should be virtually unavailable outside of demon raids and the finite few available from free quests and the like. I've found that 2-3 copies of each weapon type tends to be enough to tide me over between raids, though it can be pretty difficult to do depending on your inventory situation. There will be another raid in a little over a week.

A new (and not recommended) way to get B rank weapons is through ring recruit. Since the rates are so low it's undoubtedly not worth it to even attempt for 3* weapons, much less a specific type. Again, though, not worth trying unless the featured ring recruit is something you're interested in anyways.
