It is perfectly legal for you to manufacture your own firearm providing that:
1. It is legal for you to own a firearm;
2. You are not creating an NFA item;
3. You are not creating firearms for resale. This would make you a manufacturer and you would need a manufacturer's license.
4. You obey your state's laws.
In a nutshell, you may make your own firearm as long as you can legally own a gun and as long as it is for your own use. If you wish to transfer a home-made firearm, there is a regime whereby you can do so, but it is a drag. It is best to just build it and keep it yourself.
Now, I recently completed a KT Ordnance version of the AR-15. The receiver was anodized at home using a kit from Caswell's Plating. With the right equipment it is very easy to anodize aluminium.
The KT-10 and KT-15 can be very easily built using a drill press and handtools.
In any event, KT Ordnance will have open house events and you will be able to build your own AR on KT's CNC machine. KT will put your receiver into the machine and adjust the fixtures, and you can press the magic green button. And presto, one CNC machined AR. You will be the manufacturer, because you were one who pressed the button.
I will send Mel, some pictures of my finished build and I hope he can post them here.
Finally, if anyone is interested in learning how to build an AR-15 from a KT 80% frame, please e mail me and I will send you the instructions.
