Atflbox Spinner Target has Changed Moving Targets. We used bright orange as the color of 9 targets. So that you can stand in the distance to see the targets. Nine center mass targets spin around one central axis. Why our target is only 0.7 inches, is for better rotation. Gravity-driven speed and direction; power limited to 20 ft-lbs. For .177 caliber lead pellets guns. Before use, it is recommended to swing 9 spinning targets back and forth with your hands, wear the paint above, and the target is better flipped after being moved.
