Abstract: A frame-carried arrow rest and sideplate assembly fastened to a bow at a sight window thereof. A pin-mounted arm of the rest of the assembly is supported in a outwardly-extending, arrow-supporting mode by means of an arcuately-pivotal frame-carried support block ("sideplate") to which the arm is releasably coupled. Frictional forces applied laterally against the pivotal block upon release of the arrow and travel of the arrow shaft forwardly cause the block to pivot and to decouple from and to release the arm. The latter than falls downwardly and away, gravitationally, from its arrow-shaft supporting position to establish a clear and unobstructed travel path for the arrow shaft and its fletching as the arrow is launched in flight.
