Most rubber band guns are of repeating nature, giving the user more firepower than single shot designs.
They range from step-up-action guns and single rotor semi autos, to removable magazine automatic weapons.
These may be impractical against other automatic rubber band guns, but give the user the psychological response of real firearms.
Many mechanisms have been devised by various online designers such as: A rubber band rotary gun consists of between 3 and 12 repeater RBGs arranged on a cylindrical "rotor" as barrels.
The original tripod-mounted rubber band rotary gun, patented by Surefire Products, was featured on the Gadget Show on UK television in March 2007 and January 2010.
Motorized RBGs with rotary barrels are among the latest developments in the world of rubber band guns.
In November 2007, Anthony Smith completed the Disintegrator, a 288-shot motorized rubber band gun with 2 12-barrel counter-rotating rotors.
Through creativity and imagination, one can make detachable sights, grips, stocks, silencers, and under-barrel shotguns or grenade launchers.
In early 2007, Sebastian Dick built a motorized rubber band rotary gun entirely from Lego, capable of firing 11 rounds per second.
Lego rubber band gun mechanisms can also be used to launch light projectiles of various types, from small bricks and paper planes to wooden skewers.
