Nerf Barricade RV-10
This pistol-sized blaster uses a flywheel powered system to launch foam darts in semi-auto. It features 2 spinning flywheels positioned in a vertical layout with a 10-dart revolving barrel.
The Barricade requires 3 x AA batteries (sold separately) to operate. Simply engage the On/Off switch and the flywheels start spinning.
Every trigger pull fires one shot in a semi-auto sequence, a "dart pusher" behind the barrel pushes a foam dart in between the 2 spinning flywheels, then the flywheels will catch the tip of the foam dart and "throw" it out of the barrel. It operates on a similar principle to a tennis ball launcher.
