Kids can upgrade their firepower when they attach the Modulus
Mediator Barrel to the Modulus Mediator core (sold separately).
The barrel converts to blaster that features pressurized 3-dart
blasting. Flip the handle to go from barrel to blaster, pump to
prime the blaster, then press the button to blast a triple-dart
burst. Comes with 3 Modulus Elite darts. Customize for battle
with the Mediator core, stock, and barrel (each sold separately)
to create the Mediator XL. With the entire Modulus system, more
than 1000 combinations are possible! (Blasters, upgrade kits, and
accessories each sold separately). Nerf and all related
