An airgun has mounted, within its body 16, a pressure chamber 15 in which there is located a valve assembly for allowing compressed gas from a bottle 40 to enter a breech to fire a pellet from the airgun. The valve assembly includes an O-ring 8 which is deformed to provide an innermost sealing surface which approximates to the diameter of a gas discharge passage 2. Also disclosed is hammer assembly 30 (Figure 3) incorporating a moveable inertia weight, and a probe assembly 60 (Figure 6) incorporating an outer probe member to seal the breech end of the airgun barrel, and a slidable inner probe member which extends into the breech to position an airgun pellet therein. <IMAGE> |
