The invention provides a gunstock for BB bullet gun, comprising a gunstock body, a battery compartment provided in the gunstock body for holding a rechargeable battery, and a rear cover arranged at the rear end of the body, wherein the battery compartment is provided at the front end thereof with a fast locking conductive device; the rear cover is provided with a charging coil for charging the rechargeable battery; the charging coil contacts the rechargeable battery via a conductive elastic plate. The charging mode is changed because the rechargeable battery in the art is replaced by a wireless rechargeable battery. The battery does not need to be dismantled and taken out when charging, so that the charging becomes simple and easy to be operated. In addition, the fast locking conductive device arranged at the front end of the battery compartment and the conductive elastic plate arranged on the rear cover overcome the defects of space occupation and disorder caused by a relatively long wire needed in the art. Therefore, the invention has advantages of simple and convenient operation of charging, and compact structure.
