An elongated guide member is mounted on a bow by a support and in its mounted position the guide member extends toward the bowstring. The guide member is slidable in the support and in turn slidably receives a projectile arranged to be propelled by the bowstring. The guide member and projectile structures allow the projectile to extend beyond the rearward end of the guide member to allow the bowstring to be disposed in a bowstring nock in the projectile in the common drawing movement of the bowstring, the guide member and the projectile. A closed portion of the guide member in one embodiment has releasable structure allowing the bowstring to be moved laterally into the guiding area. In another embodiment, guide member and projectile structures allow the projectile to extend through a side slot in the guide member for engagement with the bowstring outside the guide member. The projectile in this embodiment may be provided with off-center multiple nocks. Adjustment is provided for the guide member to vary its horizontal and vertical angulation. Adjustable sights are provided on the guide member to further increase the accuracy of shooting. The support of the apparatus on the bow allows the entire guide to be turned to a position adjacent to and along the bow frame in a compacted non-use position. Adjustable friction drag device may be employed between the guide member and the support to control the slidable freedom of the guide member.
