  • Patent number: 10408580
    Abstract: The portable shooting range comprises two telescoping poles, two lines, and two clips. The telescoping poles are T-shaped and each pole provides a pulley hanging off of each end of a crossbar. The bottom of each telescoping pole is pointed for insertion into the ground and an upright provides a pair of foot braces located just above the point for pressing the pole into the ground. The telescoping poles are pressed into the ground separated by a pole separation distance and with their crossbars parallel to each other. The two lines are strung between a pulley on each pole such that each line forms a loop and the loops are parallel to each other. A clip is coupled to each line. Each clip may be used to couple a target to the line and the target may be moved downrange by pulling on the line.
