Abstract: A toy gun for firing pellets wherein a trigger operates a firing mechanism which reciprocates a hammer through a firing point in the gun barrel to sequentially discharge pellets therefrom. The mechanism is operated by an electric motor which reciprocates the hammer by means of a cam and follower mechanism. This mechanism successively withdraws and releases the hammer which is continuously biased in a firing mode by a spring. Also disclosed is a pellet delivery system in which a magazine is slidably mounted on the gun body enabling one of a plurality of pellet sources in the magazine to be in communication with the barrel and firing mechanism.
