Anyone with a 3d printer, available from several different sources at prices close to or under $1,000, can now print out parts for an AR-15 assault rifle.
The AR-15 lower receiver and A 3d printable model for a 5 round magazine .
The Lower Receiver is the frame that holds together all the other pieces of the firearm. In the States, all the other pieces can be purchased without a permit – over the counter or through the post. The Lower Receiver is the only part which requires a background check or any other kind of paperwork before purchase.
Typically this part is made of aluminium. A rifle with a Lower Receiver made of plastic can be perfectly functional.
The revolution will be printed at home.
