ABSTRACT:
An adapter for placement between to intercouple an arrow shaft with a nock for reproducibly establishing a selectable preferred orientation between a reference vane on an arrow shaft and a bowstring-receiving slot of the arrow nock which is affixed on the arrow shaft at an end thereof. The adapter and the nock carry annular markers or a scale indicia, and the adapter and nock indicia are manually rotationally displacable with respect to one another to establish selectively and reproducibly desired annular orientational relationships between the plane of a shaft-carried reference vane and a plane defined by the bowstring slot in the arrow nock. The adapter may be tapered or otherwise adapted to accommodate nocks having diameters which are less than the size of the arrowshaft.
