[Source] The Zabrak Tystel Mark III, or Zabrak Tystel Mark 3, was a powerful heavy blaster pistol model in use during the Jedi Civil War, a conflict between the Sith Empire and the Galactic Republic. Around the time of the war, the Zabrak Tystel Mark III was sold on the black market by members of the Zabrak species, who killed a large number of pirates who were attempting to steal Mark III shipments. The weapons were still in use at some point after 3662 BBY, and the Human mercenary Corso Riggs was familiar with them by the time of the Galactic War fought between the Republic and the reconstituted Sith Empire.
