Abstract: Most standard paintball markers or guns have no mounting apparatus for desired marker accessories such as a light or camera. The present invention is directed toward an accessory holder that includes a clamp adapted to be secured to the feed neck and which includes a pair of spaced apart arms carried by the clamp. The arms extend forwardly from the sides of the clamp. They are located just above the barrel and parallel thereto. The accessory is located between the arms and is secured directly thereto through the use of screws or the like or can be held by a strap connected to the arms that encircles the accessory. In addition, the vertical position of the arms can be adjusted relative to the clamp.
