ABSTRACT:
The body 12 of an air gun accommodates a removable magazine 16 immediately behind the breech 14, for pellets to be loaded one at a time from the magazine into the breech. The magazine comprises a drum 33 which is rotatably mounted within a housing 31 and comprises ten pellet-holding slots 38 around its axis. A torsion spring 42 urges rotation of the drum in indexing steps as controlled by an escapement mechanism comprising a rocking pawl 50. The pawl is displaced against the action of a return spring 58 by a plunger 60 which projects from a cocking arm 22 of a conventional cocking mechanism of the gun; the plunger is arranged to actuate the escapement only towards the end of a cocking stroke of the arm 22. A loading ram/air transfer tube 28 is reciprocated, in effecting the cocking action, to withdraw from one slot 38 in the drum and enter a next slot to load a fresh pellet into the breech.
