ABSTRACT:
An arrow with a nock assembly is disclosed. The rear end of the arrow shaft has a bore which has a rearwardly facing opening. One or more vanes are fixed to the outer surface of the arrow shaft. An adapter is mounted within the bore and is fixed to the shaft in a predetermined angular position about the central longitudinal axis of the arrow shaft relative to the vanes. The adapter has a socket which has a rearwardly facing opening. A nock which has a head end, and a bifurcated tail end, is removably mounted to said adapter so that the head end is located within the socket and the bifurcated tail end is outside of the socket. A mechanism is also provided for releasably locking the head end of the nock within the socket so that the nock is in a fixed angular position about the shaft axis relative to the adapter and the vanes and in a fixed position lengthwise of the shaft axis relative to the adapter socket opening.
