Building AR-15  Starting with 80% Lower Receiver
The advantage of an 80% lower is that the BATF (Bureau of Alcohol, Tobacco, & Firearms) does not consider it a firearm and therefore it need not have a serial number and may be shipped directly to your home.  No FFL.  No background check.  Once the AR-15 is completed, it is called a "Ghost Gun" because there will be no record of its existence.

As you may know, it is against the law to purchase an 80% lower receiver, complete it and then sell it to another party.  Finishing an 80% lower receiver requires an appropriate jig, drill and a router for the required milling.

Once the 80% lower is finished, you may complete the build of your custom AR-15.  Complete lower receiver and upper receiver kits are hard to find but still available if you do some searching on the internet.  You will generally need to catch a supplier just when they have received a shipment.  It's only taking hours to sell out on most items.  For more info on the build go HERE.

AR-15 Lower Receiver Kit
Most of the black anodized receivers are currently near impossible to find and most gun shops will not anodize a receiver that does not have a serial number.  Usually for around a $10 up charge you can order an 80% receiver with a serial number etched on it.  It does not change the status of the 80% receiver if it does have a serial number.  You may also want to have "Safe" and "Fire" engraved as well.
