Abstract: A sling bow for launching arrows has a handle to which are connected a pair of sling posts to which a twin arm sling is attached. The sling arms are made at least in part of elastic material which can be stretched and then released to propel the arrow between the sling posts. A movable arrow rest connected between the sling arms near the sling posts rises to support the forward end of the arrow when the sling is stretched. When the sling is released and relaxes the arrow rest drops out of the way of the arrow so as not to interfere with its flight. Other features include a pivoted yoke mounting for the sling post to insure uniform tension in the two sling arms and a pivotal mounting for an arm rest extending rearwardly from the handle to permit the bow to be used by both right and left-handed persons.
