The Texas Star target features five 8" diameter, 3/8" thick AR500 steel targets mounted on the rotating arms of the wheel. The arms are also made from AR500 steel for those shots that are a little off target. Shoot one of the targets off the arm and the wheel starts rotating. Try to keep up with the moving targets! As you hit each one the wheel may speed up, slow down or even reverse direction. Every shot is a new challenge.
