A firing structure of a paintball marker includes a marker body and a firing cylinder. The marker body includes a barrel with mutually communicating first and second gas chambers. A stop edge is formed in the barrel at a junction between the first and second gas chambers. An O-ring is embedded in an inner wall of the barrel at a position inside the second gas chamber. The firing cylinder and a rear guide rod are put sequentially into the gas chambers. The firing cylinder has an outer periphery formed with a stop portion in the first gas chamber. The stop portion has a front edge mounted with a buffer washer corresponding in position to the stop edge of the barrel and having a planar surface. Thus, the process yield of the marker body can be increased, and the firing cylinder remains stable in high-speed action regardless of its position.
