You can run an AR pistol if you want I suppose, but there are targets out to 500. An AR pistol will have issues in the wind at ranges over 300 I would guess. I run a 18 inch barrel so I do not lose too much velocity to minimize wind effects. You would not be able to use an AR pistol on the pistol targets due to the danger from the steel up close.
