    Abstract: A dart is provided with a pivotable flight assembly relative to the main dart body. The coupling between the flight and main body portions of the dart comprises a subassembly including a centering piston and bearing being spring-biased in a housing. The centering piston extends from the housing of the subassembly and connects to the flight assembly.
