Abstract
An outsert includes an elongated tubular member having forward, central and rearward sections, for connecting an arrow shaft to an attachment for the arrow. The outsert rearward section has a cylindrical rearward bore with a diameter greater than the outer diameter of the arrow shaft for receiving the forward end of the arrow shaft therein. The outsert rearward section also includes a tapered bore extending forwardly from the rearward bore, the tapered bore having a decreasing diameter such that the forward end of the arrow shaft contacts the tapered bore between the forward and rearward ends of the tapered bore. The outer surface of the rearward section of the outsert is tapered and receives a ferrule for crimping the rearward section of the outward into contact with the arrow shaft to assure coaxial alignment of the outsert with the arrow shaft.
