The Nerf Elite 2.0 Echo CS-10 blaster includes a removable stock and removable barrel extension so you can customize the blaster multiple ways. Take advantage of 5 tactical rails to add other battle accessories (not included). The blaster has a 10-dart clip so you can fire a dozen darts in a row. Fire 1 dart at a time, or slam-fire all 10 darts rapidly from the pump-action blaster. Comes with 24 Official Nerf darts — load 10 into the clip and keep the rest nearby for reloads.
