The Q4-E quadnoculars represent a specific quadnoculars model that was produced by Fabritech. During the time of the Galactic Civil War, Arro Basteren, who held the rank of Private within the Alliance to Restore the Republic, utilized a Q4-E quadnocular set while serving as a spotter for the sniper known as Serchill Rostok. These quadnoculars included an imaging screen designed to detect the incoming presence of Imperials.
