Ground N Pound Popper
Here we have the "Ground N Pound Popper"
The target plate is 3/8 AR 500 8" round with a 8" stem which bolts to a 12" stake.
This bad boy provides excellent visual and audible feedback between the bounce of the springs and the harmonics of all steel construction.
The pound in stake is made from 1/4" to ensure its doesn't bend going into hard/frozen ground.
