Good reference site, but I like the Midwayusa.com video's better as I feel they are more detailed. Of course they sell a lot more parts.

For the first time builder, I would strongly recommend buying a stripped AR lower (yes, you do have to go through an FFL background check and it will have a serial number) and using many of the jigs and tools to complete the lower and acquire or build your own “upper.”

While it is legal to manufacture your own “ghost gun” for your own personal use, you are never suppose to sell it or even transfer it. It is truly the fruits of your own labor.

If I am going to spend several hundred dollars on something. I would like to be able to sell it and use my acquired skills on a better product after a while.

Again, great reference.

Since it has no serial number it can't be positively identified, ergo no one can prove who did -- or more importantly, who didn't -- make it. So provided you only make them in low numbers, and only transfer them to people in whom you trust, how exactly are you supposed to get caught?

Hi Robert357, you can, in fact, sell the firearm you build. The ATF makes a distinction between a manufacturer and a builder. The wording of the relevant law only states one cannot build a firearm with the intent of selling it. Building a homemade firearm and deciding to sell it later is perfectly legal. Midway's guide is centered on assembling a rifle itself, whereas this guide focuses entirely on completing fabrication of the receiver blank. If you'd like more detailed information on building an AR-15 - and all the other necessary parts and steps - I recommend starting off here, How to Build an AR-15: The Complete Parts Guide.
