A small Riker box containing a variety of CIA Vietnam Era MB Associates manufactured microjets including a Finjet, metal nose, propellant and a multiple-round holder all in very good condition. MB Associates (MBA) Gyrojets were a series of experimental 1960s firearms designed by Robert Mainhardt and Arthur Biehl that fired miniature, fin-stabilized rockets (known as "Microjets") instead of conventional bullets. These weapons, including pistols and carbines, were intended for high-power, quiet, low-recoil operation but failed commercially due to high costs, inaccuracy, and poor reliability.
