The utility model provides a pressure self-adaptive light-gas gun piston, which ensures air tightness by utilizing self-adaptive deformation of the piston along with pressure, and can effectively solve the problem of air tightness of high-pressure gas at two axial ends in the high-speed movement process of the piston. The pressure self-adaptive light-gas gun piston comprises a piston body, two extrusion blocks and a connecting rod used for connecting the two extrusion blocks. The piston body is of a cylindrical structure with a center hole, the two axial end faces of the piston body are each of an inward-concave structure, and the piston body can expand and deform outwards under the action of pressure. The two extrusion blocks are arranged in the inwards-concave structures of the two axial end faces of the piston body respectively, and the connecting rod penetrates through a center hole of the piston body and then is connected with the two extrusion blocks respectively. 本实用新型提供一种压力自适应轻气炮活塞，利用活塞随压力的自适应变形来保证气密性
