Abstract: An apparatus and method for casting a hand bow in a horizontal orientation, to provide reduced forearm slap, increased accuracy, and reduced grip arm fatigue. The horizontal orientation also enables the bow assembly to be used in seated and prone positions, as well as when standing. A grip member having a rearwardly facing alignment channel is mounted or formed on the riser of the bow. The channel is configured to receive and engage the metacarpal head area or another portion of the grip hand so as to form a horizontal pivot axis. The pivot axis is positioned in substantially the same plane as the primary plane of the bow assembly, thereby minimizing development of torque when the bowstring is drawn. A bracket assembly is provided for mounting an arrow rest and sights for use in the horizontal orientation.
