Do All Outdoors 40 Target Extension Kit is a simple accessory to almost double the target capacity of the Aerial Assault Automatic Trap. The kit comes with 4 stainless steel tubes and one support collar. The tubes screw into the existing tubes on the trap and within seconds the capacity goes from 50 to 90. The shooter can spend more time shooting, instead of refilling the trap with targets. The ease of use and durability makes this a perfect accessory for the Aerial Assault.
