ABSTRACT:
An arrow nock system for use with an arrow. The arrow may include cylindrical shaft with a frusto-conical projection at the rear. A butt piece with a complementary frusto-conical interior bore is secured to the projection. The butt piece includes a proximal half, closer to the arrow, with a cylindrical outer surface equal to the diameter of the arrow shaft, and a distal half with a frusto-conical outer surface. Near the outer end of the distal half is an annular indentation. A nock piece includes a frusto-conical interior bore complementary with the distal half of the butt piece. The bore includes an annular protrusion engageable with the indentation in a rotatable snap-fit. The nock includes a cylindrical outer surface, and a groove at the rear to receive a string of a bow.
