The 3D printing wars are hotting up, as Thingiverse users upload a design for an AR-15 magazine (holds five rounds, easy to expand to as many rounds as the material will hold without snapping) and an AR-15 lower receiver, a component whose ownership is proscribed or regulated in most of the USA.

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.

Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
