Another gun discussion part deux.

pretty sure jigs are not allowed. on the official documentation it approves only two tools. a hand drill and dremel. maybe it is state to state, but i know they crack down on people who buy 'manufacturing equipment' to process the 80% lowers. if you but things like lathes and drill presses they want you to get your manufacturing license.

I am 100% percent sure that jigs and whatever machine tools (including 3d printers) you want to use are legal for non-licensed individual to use to manufacture a gun for their own use. The only federal requirements for making a gun for yourself, as long as it does not require a NFA classification, is it is not intended for resale, and you can legally own a gun. Most states follow this model, but some require a things like a FOID and identifying marks such as manufacturer, place of manufacture, model number, and a serial number. You can even sell it after you are done as long as you didn't manufacture it with the intent to sell, but you have to add the identifying marks if you do.

What is not legal is to get someone else to finish an 80% for you. Then they are the manufacturer not you. If so they have to follow all the rules of a firearms manufacturer including performing a background check before they transfer something they made to a non-FFL. So you can't just take your 80% receiver down to the local machine shop and have them finish it for you, but you can certainly use your own mill, or one of dozens of different jigs available to make a perfectly functional and legal firearm with lesser tools.
