Duenan's 10-gauge, Gong

In Masume Shirow's popular Appleseed manga, the lead heroine Duenan carried a 10-gauge shotgun pistol she called a gong. This was the first prop Robin Yang ever made back in '87 when Lazer Tag was popular. Believe or not he managed to fit the electronics to a Lazer Tag rifle inside the shotgun, and used it to great effect.
