So simple, I'm embarrassed I didn't think of it. This is 10" of steel pipe, about 2" diameter, and an ideal knock-down target for birdshot. Since it's cylindrical, it reduces the amount of lead spraying back at the shooter.
Simply stand it on one of our KnockDown Bases, or perhaps your own wood stand, or even stand it up on the ground.
Spraypainted, usually red. Thanks to 3Gun shooter A.M. for mentioning this simple and reliable birdshot target!
