For some reason the US News media decided on the AR-15 as the poster child of guns that should not be allowed to be made for, or sold to, the consumer. The words still out on the regulation, but, in a very American response, a whole market sprang up around people saying, “Well, then we’ll just make our own AR-15.”
Ordinarily, we wouldn’t cover this sort of thing, but the work [AR-15Mold] is doing is just so dang interesting. They sell a product that enables the home user to cast an AR-15 receiver out of high performance resin. In the process they made a really informative three part video on the casting process.
A lot of people are interested in the product, and having fun with it. In this two part video series, [Liberty Marksman] cast their receivers and test them to destruction. In one video they see how many rounds they can fire out of the gun before it breaks. When it breaks, they excitedly tear down the gun to see where it failed.
It’s quite a bit of fun to watch. Videos after the break.

[Boris] must have been a little bored over Thanksgiving. We’re guessing that’s the case; why else would he build an AK-47 out of a common garden shovel?
After buying an old shovel from an antique barn in Vermont, [Boris] cut off the handle an attached it to an old Bulgarian AK he had just lying around. The new stock proved to be very comfortable, and not wanting to waste the iron in the shovel head, decided to make an AK out of the remainder of his purchase.
After tossing the shovel head into the furnace and pounding it flat, [Boris] had a respectable piece of metal to construct an AK receiver from. A bit of plasma cutting, grinding, and drilling turned this former shovel into a future gun, and with the help of a blank barrel the shovel became an AK receiver that is twice as thick and twice as heavy as a ‘normal’ AK receiver. Yes, [Boris]’s new gun is even more indestructible than a stock AK – something that really shouldn’t be possible.
In the end, [Boris] spent $2 on a shovel, $30 on a barrel, and $200 on a Romanian AK kit. The result is an actual, working gun that is legal for him to own (but not sell – see the comments for that discussion).
For as long as they’ve been banded about, 3D printers were regarded as the path to a new economy, a method of distributed manufacturing, and a revolution for the current consumer culture. With every revolution, a few people need to get angry and the guys at Defense Distributed are doing their part to make that happen. They’re designing a handgun able to be printed on a hobbyist-level 3D printer
This isn’t the first time we’ve seen a 3D printable weapon; this 3D printed AR-15 lower receiver is the only part of an AR-15 that contains the ID markings and serial number. Legally, the AR lower is the gun, and requires a background check to purchase (with the footnote that this varies from state to state and country to country – long story short, the BATFE probably isn’t happy about a 3D printed AR lower). The one drawback of a 3D printed AR-15 lower is that every other part of the gun must be purchased elsewhere. This is where Defense Distributed comes in: they propose designing a gun that is 100% printable on a hobbist-level 3D printer such as a RepRap or Makerbot.
Right now, Defense Distributed is looking for funding to produce two gun designs. The first design, WikiWep A will serve as a research build, allowing Defense Distributed to answer a few questions on what can be built with a RepRap. WikiWep B will have moving parts for the firing action and very nearly all the parts will be printable on a RepRap or Makerbot.
In the video Defense Distributed put up for their now cancelled IndieGoGo campaign (available after the break), the guys talk about the distribution of a CAD file of completely 3D printable weapon being a threshold of a new economy where laws and regulations cease to apply. We’re not sure we agree with that statement; after all, anyone with some metal forming tools can build an excellent weapon to acquire another weapon, but we’re interested in seeing what governments and regulators will make of Defense Distributed’s project.
