1. A nock insert comprising:
- an axis of elongation defining an axial direction and radial directions;
a bowstring reception surface adapted to receive an associated bowstring;
an insert portion adapted for insertion into an associated arrow body;
a first centering feature comprising a first spring tab having;
(1) a first end attached to the insert portion; and
(2) a second free end extending axially from the first end and having a contact surface; and
a second centering feature comprising a first spring tab having(1) a first end attached to the insert portion; and
(2) a second free end extending axially from the first end and having a contact surface;
wherein;
(1) each radial direction is perpendicular to the axial direction;
(2) the contact surface of each spring tab is inherently biased outwardly in a radial direction and adapted to be radially deflected upon insertion of the insert portion into the associated arrow body;
(3) the contact surface of each spring tab is adapted to provide a radial reaction force on, and a corresponding frictional retaining force with, the associated arrow body when operationally engaged therewith;
(4) the contact surface of the first spring tab of the first centering feature extends in a first axial direction;
(5) the contact surface of the first spring tab of the second centering feature extends in a second axial direction that is opposite the first axial direction;
(6) a first radial line that intersects the contact surface of the first centering feature does not intersect the insert portion; and
(7) a second radial line that intersects the contact surface of the second centering feature does not intersect the insert portion.

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.
