When World War II came, the Danao gunsmiths went underground, joined the guerrilla movement or were inducted into the USAFFE. Their main task was to re-chamber the Japanese Arisaka rifles to fit the US .30 caliber round or to keep the original Japanese rifle in good service. The industry went on, still underground. In the 1960s, the term paltik was given to the homemade (and illegal) guns.[citatio
