While the Astromechs are the park BAD molds, the BB units are Hasbro molds. The park BB units are 4 pieces (head, core, 2 part shell) while these are the same molds from the Rose (First Order Disguise) set in different colors. I don't mind them reusing the Hasbro molds though as the park molds are too big to scale properly with 3.75" figures.
