The K-Flight system. A high performance all in one flight and shaft system featuring Target’s patented twist system. The precision moulded system key features: Lightweight: K-System flights are lighter than other moulded systems on the market allowing for a more consistent throw. Patented Flex System: The shaft section of the K-Flex has been designed to move if hit by another dart, reducing the chance of a bounce out. 90 Degree Precision: Our injection moulding process means the flights are at perfect 90 degree angles out of the box and through their playing life. Durability: A slight increase in thickness to the front and back edge of the flight increases durability dramatically over other flight types.
