Arrow rest arrangements according to certain embodiments include an elongate arm mounted to extend into and rotate in the plane of an arrow aligned with an archery bow and riser. The arm can rotate from an open position, for example where the arm is substantially perpendicular to the arrow shaft, to a closed position where the arm engages and may be substantially aligned with the arrow shaft. The arm preferably includes two opposing end portions to engage, constrain and align the arrow shaft in the closed position, yet which drop or rotate away from the shaft upon release of the arrow to allow the arrow to freely leave the bow.
