Upgrade your firepower arsenal and extend your Nerf blaster with help from the Mediator Barrel for the Nerf Modulus core (sold separately). Use the barrel to create a pressurised blaster that can shoot three darts at once. Simply turn the handle to switch from barrel to blaster, pump it up and fire a triple dose of darts. If you detach the barrel extension from the blaster body, release the grey handle and use it as a separate weapon. Become a full-fledged warrior and put together your Mediator XL blaster and Mediator Barrel (each sold separately). More than 1000 combinations can be created with the entire Modulus system. 3 Modulus Elite darts are included.
