This accessory attaches to your existing PRS Plate Rack from MGM. Install the legs to the beams, bolt to the PRS and off you go. The targets are made of the same AR500 3/8” steel as the original Plate Rack and will turn your old target into something challenging, exciting and tons of fun. These additional 12 targets DO NOT automatically reset. They must be hand reset. The targets are manufactured at an angle and in diminishing sizes so the targets are not visible until the first target is successfully engaged.
