"WarFairy’s Latest Additions To The Charon Line Of Printable AR-15s′"
30 May 2013. From the P-15, it was integrated with the DefDist V5 lower receiver, resulting in the WarFairy Charon V0.1. Further advantage was taken of the nature of
FDM polymer printing to make it possible for printers with small work envelopes to produce large items, i.e., the Charon was designed to be printed in sections and then assembled with solvent cement.
The Charon pistol version was successfully test fired in July 2013 with no sign of damage.
