The new K-Flight system from Target is a high-quality all-in-one flight and shaft system with Target's patented rotation system. Key features of the new system: Lightweight: K-System flights are lighter than other systems on the market, allowing for a more consistent throw. Patented Flex System: The shaft portion of the K-Flex is designed to move when struck by another arrow, reducing the chance of bounce-outs. 90 degree precision: The special molding process ensures that the flights have a perfect 90 degree angle out of the box and throughout their playing life. Durability: A slight increase in thickness at the leading and trailing edges of the flight dramatically increases durability compared to other types of flights. Dimensions: Available in Short, In Between and Medium
