The attachment includes a tubular barrel through which a ball or other missile is projected by the force of the bowstring. The tubular barrel is rigidly attached at its muzzle end to the central portion of a bow, and is provided with elongated slots along its upper and lower surfaces through which the bowstring passes. Within the barrel a slidable carrier is attached to the bowstring. The carrier releasably holds the missile even when the barrel is tilted downward as well as when the bow is drawn. When the bowstring is released, the carrier and missile are driven toward the muzzle of the barrel; but, when the bowstring and attached carrier decelerate as they approach the muzzle, the momentum of the missile causes it to pull free of the carrier and to continue through the muzzle toward the target, while the carrier remains behind in the barrel. The attachment is removable from the bow and adjustable with respect to it.
