The Magpul FMG-9 is a prototype folding submachine gun, designed by Magpul Industries in 2008. It is made out of polymer in place of metal, reducing weight. The FMG-9 never left the prototype stage, and never saw widespread production on any level, as the item was only produced by Magpul as a proof of concept.
