This is the N-Strike Raider Rapid Fire CS-35. This is a pretty awesome gun. It is the highest dart capacity gun that Nerf has to offer, holding 35 Nerf Clip System darts. This is made possible by it's drum magazine. The drum magazine features a clear window to keep track of ammo consumption. The really cool thing about this "drum" is that it works with the other magazine style Nerf guns such as the Deploy CS-6, Longstrike CS-6, Longshot CS-6, etc. The Raider also features a single or multi-shot mode. Pump the front handle back then forward and pull the trigger for single shot and for raid fire hold down the trigger and pump the forward handle as fast as you can. When firing in rapid mode I have found that the better you can "rack" the forward handle all the way back and all the way forward you have less problems with jamming. Another way to avoid jamming problem is to keep the darts in good condition. The more the darts get torn up or bent the worse they fire. The stock also extends or comes off which is pretty cool. A "must have" for your Nerf collection.
