Abstract: An archery bow with a riser including a mount in a centerline plane of the riser above a lower wall of a sight window of the riser may allow for a novel manner of mounting an archery accessory. Placement of the mount within a centerline plane of the riser may maintain the weight of the archery accessory along a center of the bow, thereby reducing or eliminating asymmetrically weighted bows or the need for an additional stabilizer to balance the weight of the archery accessory. Positioning the mount above the lower wall of the sight window additionally allows for coordination of the position of a secondary accessory, such as a sight, a light, or a camera, in addition to mounting an arrow rest, such as in a lower wall of the sight window, while maintaining the centralized weight advantages noted above.
