The Nerf  Rayven is a battery powered Nerf Blaster.
It comes with :

The Rayven Blaster itself
One battery powered 18 dart clip
18 glow in the dark darts

The reason the clip is battery powered is so it can charge the darts with LED lights
It also has 2 Tactical rails and a barrel attachment

Overall it is a gun to really use for dual guns because it is a good size gun to use

You should really buy this gun with a price of  $30 well that's what i got it for.
