A bow stabilizer incorporating one or more attachment rails for mounting a variety of accessories to the stabilizer for use in conjunction with the bow or other target sighting device. The stabilizer is rotationally adjustable about a center axis attachment post connecting the stabilizer to the bow. In addition to rotating the stabilizer for balance, the rails are individually adjustable side to side at their ends and are preferably of the picatinny or weaver rail configuration. Anywhere from one to four (or more) accessory rails may be positioned symmetrically or asymmetrically on the stabilizer. One or more counterbalance weights may be adjustably positioned on one or more of the rails to offset and balance the weight of attached accessories.
