Abstract: A nock insert may have an axis of elongation defining an axial direction and radial directions, a bowstring reception surface adapted to receive a bowstring, and an insert portion adapted for insertion into an arrow body. The nock insert may have one or more centering features having one or more spring tabs. Each spring tab may have a first end attached to the insert portion and a second free end extending axially from the first end and having a contact surface. The contact surfaces of each spring tab may be inherently biased outwardly in a radial direction and adapted to be radially deflected upon insertion of the insert portion into the arrow body.

Abstract: Provided is a universal nock system comprising a first axis defining an axial direction and radial directions perpendicular to the axial direction; a nock having, a first side having a bowstring reception surface having concave channels, a second side opposite the first side, an axial contact surface, and an exterior surface; an insert portion extending from the second side of the nock, elongated along the first axis, and adapted for insertion into an associated arrow body, the insert portion having, a first end, a second end opposite the first end having a centering feature of the second end, the centering feature of the second end having contact surfaces, and a middle portion located along the first axis of elongation between the first end and the second end, the middle portion having a centering feature of the middle portion, the centering feature of the middle portion having contact surfaces.
