Kids (and let's be real, adults too) are going to go absolutely nuts over this Nerf Hyper Mach-100! This thing is fully motorized and can fire rounds at up to 110 feet per second - that's some serious velocity! The massive hopper holds 100 rounds, and you get 80 Hyper rounds included to start your battle. The tactical rails let you attach reload canisters (sold separately) for quick refills mid-game. The motorized action means you can just hold down the trigger and unleash an absolute hailstorm of foam. Requires batteries (not included, so grab some!) and comes with safety eyewear because let's face it, at 110 FPS you want eye protection. The Hyper rounds have this cool innovative design that maximizes speed and capacity. Perfect for backyard battles, birthday parties, or just driving your parents crazy indoors. The build quality feels solid - not some flimsy plastic that'll break after one good drop. If you're tired of constantly reloading during Nerf battles, this massive capacity blaster keeps you in the action way longer. Just be prepared for the inevitable 'I want one too!' from all your friends once they see this beast in action. Seriously, this might be the most fun you can have with foam projectiles!
