Yes, but at the range I belong to they will not allow targets to sit ground level. So no shooting bottles or cans or walkers on the ground, too concerned about ricochets. It has to be 18" off the ground and less than 2 feet from the berm.
That walker is pretty cool though. I'd actually prefer that over some hanging steel just because it moves and you have to readjust.
The walkers are fun as hell. You should hear all the "oh ****s" and "damnits" when you use one walker for multiple shooters. It's hilarious!!
