Target Play Dart Flight Slot Punch
Lock your flights to any nylon shaft by popping a flight into the front of the punch, the built in guide will align the fight correctly, then simply push down punch a slot into the flight. You can then insert a spring or ring into the slot, open the flight and attach to your nylon or plastic shaft. The flight is now firmly attached and won’t pop off during closely grouped throws.
This system will also reduce Robin Hoods and increase shaft life.
