The Caldwell AR500 Plate Rack Kit brings competition-style targets to your home range. Each kit includes Three - 8" diameter targets with hanging brackets and 2 steel 2x4 frame hubs. The targets and target brackets are constructed of rifle-rated 3/8" AR500 steel for use with handguns and centerfire rifles. The steel frame hub brackets use standard 2x4 lumber (not included) to construct a customizable frame size that is easily expanded with the target expansion kit (sold separately). Dual functioning plates can be shot as falling plates or they can be suspended and shot as static/swinging plates. Have a blast setting them up and knocking them down with the Caldwell AR500 Plate Rack Kit.
