My opinion, looks like a target.
Up in our neck of the woods, here is what we do, see?
We find a stump.
You with me, so far?
Just checking.
We set the contraption on the aforementioned stump.
.
If today is 'pxstol' time, we step off a hundred paces.
Clear the lane, open fire, destroy the invaders.
.
If today is 'rxfle' hour, we usually start the youngsters at 600 paces, then increase that as they gain years.

Second place for targets is their cardboard boxes.
