DIY Pop Bottle Airsoft Machine Gun

 

This DIY Pop Bottle Airsoft Machine Gun should cost $10 to $15, doesn’t use any parts that can’t be found at your local hardware store and should take less then an hour to build. Best of all if you have a compressor handy you can shoot the thing to your hearts desire. You might run out of targets to shoot in a hurry though since it has a very impressive fire rate!
