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. The flight assembly is then pivotable with the centering piston acting on the bearing to reduce deflection of subsequently thrown darts.
