ABSTRACT:
A dart comprises a shaft having a flight lock for securely mounting a flight on the shaft. The flight lock comprises a threaded post extending rearwardly from the shaft body and a flight holder mounted on the post. The flight holder has a threaded axial bore at its front end for receiving the post and an X-shaped slot at its rearward end which extends forwardly to a position overlapping the bore. A flight is inserted into the slit and is pushed forwardly until it enters the back of the bore. The flight holder is then threaded onto the post until the post engages the flight and wedges it between the post and the wall of the flight holder defining the bore.
