An arrow brake for attachment to the shaft of the archery arrow. The brake impedes and effectively prevents the released arrow from passing entirely through the body of a target impinged by the arrow. The brake includes a relatively thin and flexible ring for sleeved frictional engagement on the arrow shaft. Attached to and extending radially of and forwardly of the ring are annularly spaced wedge-shaped probes. Engagement of the probes within the body of the target causes the probes to pivot arcuately, upwardly and rearwardly, to define a segmented wall generally normal to the arrow shaft to impede travel of the arrow shaft through the target body. Stops integrally formed with the probes pivot with the latter and come to abut the surface of the arrow shaft rearwardly of the ring thus limiting further arcuate displacement of the probe elements. In a preferred embodiment of the invention the arrow-shaft-engaging inner annular surface of the ring is cylindrical. Distortion of the ring in response to bending forces applied thereto as the probes are arcuately pivoted causes the ring to twist and distort with the effect of reducing the effective inner diameter of the ring. Gripping of the ring on the arrow shaft is thereby significantly enhanced, and rearward sliding of the ring on the arrow shaft is deterred.
