An air gun having a fixed barrel mounted on a body and a source of compressed air or gas housed in the body has a device for enabling a pellet to be inserted directly into the barrel. A breech block is angularly movable between a loading position in which the breech is exposed and a firing position in which the breech is closed, the breech block having passage for completing the connection between the breech and the source of compressed air. In the embodiment shown the breech block is cylindrical and is rotatably mounted in a continuation of a cylinder in which a spring urged piston works, and has a guide chute in its cylindrical surface to assist the introduction of the pellet. Seals may be provided at either end of the breech block. |
