Abstract: An arrow insert is inserted into an arrow shaft. The arrow insert includes an outer end with a head, which is located against a leading end of the arrow shaft. An interior diameter of the arrow insert is machined as to accept a threaded arrow tip. To assemble the arrow insert with the arrow, the neck of the arrow insert is coated with an adhesive and inserted into the arrow shaft. The head of the arrow insert has an angular undercut, which is substantially concave. The angular cut of the head is a mating surface for an angular cut on the leading end of the arrow shaft. The substantial concave surface of the arrow insert and the substantial convex surface of the arrow tube prevents the rearward movement of the arrow insert, and the mushrooming of the leading end of the arrow shaft.

Abstract: A dual step insert includes a head portion, a front neck portion, and a rear neck portion. An extension shaft is a tube shaped portion that includes an outside diameter, an inside diameter, and a wall thickness. An arrow shaft is a tube shaped structure that includes an outside diameter, an inside diameter, and a wall thickness. An outside rear neck portion of the dual step insert is used as an adhesive surface to adhesively couple the rear neck portion inside the front end of the extension shaft. Coupling of the dual step insert and the extension shaft create a dual step insert. The outside surface of the front neck portion and the outside surface of the extension shaft are now the adhesive surface for the dual step insert, which is adhesively coupled into the arrow shaft.

Abstract: An archery arrow carries a light transmitting nock plus a light assembly, which comprises a light source positioned so that the light source is visible through the nock, a switch having normally open electrical contacts, and closable upon momentary contact with a magnetic field, and circuitry interconnecting a battery, the switch, and the light source for permitting illumination of the light source when the magnetic field is sensed. By this invention, the light assembly may be free of a housing and occupies a first bore of the nock and a second bore of the arrow shaft rearward end. A unique system for retaining a battery and protecting against high G force, plus a focused beam LED are other optional, advantageous features.
