The Average Airsofter goes into his collection of airsoft parts to see if he can put together a complete airsoft gun. It's good to watch this, especially for beginners so they can check what they have to do if they want to make an airsoft gun based on what is available to them... "This is an m4 that I built for 0 dollars out of pocket! If you have a few parts laying around then this could be a fun side project. Airsoft parts are getting more and more compatible, so this could be a good option if you want to get into the sport."
