Abstract: An anti-vibration damping device for the main spring of a piston air gun comprises an insert body extending longitudinally within the spring coils and a locating portion at one end on which an end of the spring seats, the insert body including resilient limb formations which are radially expanded to engage the interior of some of the spring coils.

Abstract: A spring-energized air pistol or other air gun has cocking mechanism, typically lever actuated, e.g. utilizing break action of the gun barrel itself, for urging the air piston to the fully cocked position which operates in at least two stages, two or more strokes of the lever being required for full cocking. Initial strokes of the mechanism move the piston to one or more successive intermediate positions and, in some applications, the gun may be fired from the or an intermediate position enabling it to be selectively used at less than full power.
