Rubber band gun Rubber band gun A rubber band gun, often abbreviated to RBG, is a toy gun used to fire one or more rubber bands (or "elastic bands"). Rubber band guns are often used in live-action games such as Assassins, in which they are common and popular toy weapons. They are also common in offices and classrooms.

A manufacturer has a size 117A (1/16 inch wide) and a 117B (1/8 inch wide). Another distributor calls them 7AA (1/16 inch wide) and 7A (1/8 inch wide) (but labels them as specialty bands).
