Kids can build the Mediator XL blaster with the Nerf Modulus Mediator Series. The series includes a blaster core, barrel, and stock (each sold separately). The Mediator core blaster fires 6 darts in a row with pump-action, clip-fed blasting. The clip loads into the side of the blaster and holds up to 6 Elite darts. Unleash all 6 darts rapidly with slam-fire action. The Mediator blaster has attachments points for the Mediator Barrel and Mediator Stock, so battlers can build the Mediator XL blaster. Side and top tactical rails provide places to add Nerf Modulus accessories for more customizing options. With the full Nerf Modulus system, create over 1000 different combinations! (Barrel, stock, and other accessories each sold separately.) Nerf and all related properties are trademarks of Hasbro.
