Nerf N-Strike Barricade RV-10 from Hasbro

The Nerf N-Strike Barricade RV-10 blaster is a motorized, semi-automatic blaster with a revolving dart barrel that unleashes a barrage of up to 10 darts. The Barricade RV-10 holds up to 10 whistler darts (They are called "whistler" darts because they make a whistling sound as they fly through the air.) and is compatible with the Nerf Tactical Rail System and alternate N-Strike stocks. The darts are easy for kids to load, and the RV-10 itself is easy to use. Simply turn it on and push the trigger to fire. http://www.timetoplaymag.com/toys/2368/hasbro/nerf-n-strike-barricade-rv-10/
