This is our 15 inch 16-gauge popper times two! Great for shoot off’s, each popper falls independently when hit and when at rest lying flat, are overlapped to determine which popper went down first.  All you have to do is see which one is on the bottom after the shooting stops to know who won!  They feature individual calibration screws and a felt bumper to cushion the fall. The unit measures 8x15.25x2.75 and weighs 3 pounds.  The base is composed of one inch square tubing in a uniquely curved "T" configuration. All hardware is 1/4 inch and zinc plated.  The 16-gauge construction will stand up to a lifetime of shooting even with the most powerful of airsoft guns.  DO NOT USE WITH STANDARD FIREARMS.
