Black Powder Matchlock Barrel/ Faux RPG. 28g Black Powder Matchlock Barrel attached to faux RPG. Barrel is 16 inches matchlock fuse ignition for black powder only. Barrel is permanently attached to faux RPG launcher. RPG is non functional, it is not real. I sell these to Viet Nam and Iraqi vets who use them to make wall museums of their military service. Matchlock Barrel uses .52 round ball with patch or pellet load and 50 grains of Black Powder only.
