Abstract
A kit for assembly and attachment to a crossbow that will adapt the cross bow to shoot arrows (e.g. 6 inches long) which are several times shorter than arrows of conventional length (e.g. 22 inches) normally shot by a crossbow. The kit includes an elongated track or guide assembly through which a short arrow is guided as it is being launched. The track assembly is mounted on the stock of a crossbow by a front clamp which supports the muzzle end of the track assembly and a rear receiver which supports the breech end of the track assembly. A short arrow loaded from the muzzle end into the breech end of the track assembly is releaseably retained in place against premature dislodgment by gravity or otherwise by a spring which presses an arrow shaft-engaging shoe into retaining engagement with the shaft of the arrow. The invention also comprises the short arrow adapted to be launched and shot from a crossbow equipped with the kit.
