Feed the PVC tubing into the back hole of the gun(only about an inch or so). You can duct tape it to the gun if you'd like(thats what i did). Make sure the valve is closed and use a bike pump or air compressor to pump up the chamber. I forgot to add a gauge to see how much air is in it. Pump it up to what you think is right. Im not reasponsable if you blow it up. It should be no more than about 20psi. Load a foam dart in the end of the barrel and make sure it slides down to touch the end of your PVC tubing. Simply Turn the valve( faster the better) and Swoosh, the dart will go flying. I shot about 30 yards with it. Tell me how far yours will go. And please, dont use a projectile that could hurt someone, stick with the foam darts. They are still very much fun. Thanks.
it takes a while to figure out the perfect length though
