This customizable launcher features a hopper-style ammo container that slides open for quick and easy refills. Kids can enjoy rapid fire shooting with 20 foam balls that rain out of a high-capacity magazine at super fast speed and low impact; compatible with major brand darts. Built-in, anti-jamming hatch prevents firing when open, keeping your fingers safe from injury during maintenance. Don't stress taking time to charge, as it uses 8 AA batteries (not included) to power the electric fan launching system and automatically moves ammo into the firing chamber. Product dimensions 22 x 3 x 10.5 inches.
