The FMGC-01 is a compact, select-fire version of the FGC-9 9mm carbine which is currently being developed in Europe to further counter gun control. Like the FGC-9 it uses 90% 3D printed parts mixed with metal bits readily available from any hardware store or Aliexpress.
But What about the ammo?
People simply buy ‘inert rounds’ from any surplus store and reload them using powder from nail gun blanks, a process which has been extensively documented in a guide released by Deterrence Dispensed. The primer compound in the base of the blanks is scraped out and used to reactivated the spent primers.
