A small diameter crossbow bolt (100) includes a small diameter shaft (102) having a leading end (103) with an insert (104) to receive a point (106). The trailing end (107) of shaft has a nock (108) and adjacent fletching (110). The insert receives a point, such as a target point, broad head, or other point known in the industry. A circumferential spacer (112) is positioned along the shaft between the insert and nock and moved along the shaft as needed to locate the insert for a particular weight distribution, center of gravity positioning, or to separate the spacer from nock. The insert, nock, and spacer each have a diameter substantially equal to the diameter of a prior art bolt. When the diameters of the nock and spacer are equal to the diameter of a prior art bolt, the small diameter crossbow bolt of the present invention can be used interchangeably with prior art bolts without modification to the crossbow. |
