Printed AR-15 Magazine data now free for all
Gun Watch ^ | 9 January, 2012 | Dean Weingarten

Posted on 01/08/2013 8:47:18 PM PST by marktwain


Defense Distributed has created a website that is the "island of misfit (firearms) objects" that others have censored from the web. Chief among these are the data to print a complete, functional AR15 magazine, including the spring.

The current data is limited to a five round design, but it appears that it could easily be altered to a 10, 20, or 30 round design, especially if the maker is willing to add cheap and reliable steel springs.

The necessary springs can be hand made from wire, if desired.

It just goes to show you that someone could clandestinely make darn near anything they wanted to with the right equipment, knowledge and time. Forging a decent barrel would be the hard part.

“Forging a decent barrel would be the hard part.”

A Sheriff friend of mine made all his own rifles mostly with a lathe that he shot national matches with.

He was an undercover narc and nothing short of deadly with handguns and rifles!!!

Fortunately, that piece is not controlled and requires no checks to purchase. With a blank of the proper size and a metal lathe, you can turn whatever you need.

Technology is indeed now at the point where you can make just about anything without requiring a large machine shop.

I would never advocate doing anything illegal, of course. Just affirming that home manufacture of darned near anything these days is indeed possible to do.

what is the big deal with barrels?

the barrel does not have a serial number,
so it can be bought by mail order,
just like any ordinary machine part.

Excellent, now who can design a simple Liberty Pistol of the Next Generation? Simple single or double barrel construction. One time use like a disposable tool.

And it better not be a wheel gun or an AR with junk.

As long as one had the proper sized spring making a 5 round in to a 20 or 30 round mag wouldn’t be hard.

One could even use wood as the lower body of the mag.

When millions of recently armed Americans will have to go up against a superior armed and supplied police state they may need something more than just their numbers and bad breath.

Myself I would think that in the near future we will see people taking a 3D printer to make all the sear parts in the AR that allow a conversion to 3 round burst or full auto.

Though these may be resin parts they can be plugs for molds that in turn can be used for cast metal, or copied for those that have mills or lathes.

Either way the 3D printer will be like giving the Confederate Army AK 47 rifles against single shot rifles of the Union Army.

And they are of course out of stock. This is getting ridiculous. Does Brownells have anything that is actually IN stock? We need to find an alternative - a rectangular spring that’s about 18x45mm of the proper strength and length or longer but intended for an application other than a rifle magazine.

Is it a waste of ammo if its coming at you?

I can just imagine a firefight and a lib who decided he needed an AR complains against a gang shooting at him during a drive by, “You’re wasting ammo!”

The flat parts can be made from aluminum, and the follower I can make from a mix of JB Steelweld and a little bit of dry graphite, makes it nice and slippery. The spring is a no brainer unless a no brainer tries to duplicate it then you create a black hole.

Sustained, accurate fire is FAR more effective than inaccurate spraying. 3-round burst and full auto from a 30-round magazine can not be sustained and it is very inaccurate. Stick with the “Semi” position on the selector switch.

My FRiend, we have millions of new AR owners all of a sudden out there, I doubt there is a high percentage who know about sustained accurate fire. And a trained police force also know all about how to counter direct sustained fire, but just how well can they handle a wild wall of lead coming from all directions?

Sometimes crazy and wild is the only answer.

No, but Russian revolutionaries made their own dynamite.

The big deal with barrels is there are very few manufacturers, which can be shut down by an oppressive government with little difficulty. No barrel, no gun. Insofar as they can be made at home, quality and production rate are nothing like writing large checks and having truckloads delivered from economically captive producers.

Remember, when TSHTF the purpose of your civilian weapon will be to obtain a military weapon. This is the lesson of countless revolutions and insurgencies.

That said, you can't drop an M16 fire control group into an AR15 receiver. There are several key differences that make it difficult to militarize an AR even with the proper parts. If someone wants to provide a REALLY valuable service, they could post a printable M16 receiver. Or better yet a printable M14 receiver!

A “Liberty Pistol” would be a fine application for 3D printing. Because it is basically a “gun to get another gun” it need not be complex or even particularly powerful. A great project would be a single shot suppressed .22 LR pistol. The supressor would be a once-and-done affair, which would be fine for the intended application.

There aren’t “very few” manufactures of barrels.

There are dozens of them, of varying levels of quality.

What isn’t there are abundant sources of barrel quality steel. Seems that the “free trade uber alles” crowd thought that making steel was an icky, dirty industry best outsourced to people in the third world, who wouldn’t know quality steel if it were applied to their faces like a baseball bat.

Want to make a barrel? Get an axle out of a car or truck. They’re made form 4140 steel. This isn’t rocket science. It’s deep hole drilling, followed by reaming to size, and then you get your choice of broach or single-point cutting. The twist can be imparted with a sine bar, as was done on the P&W machines of over 100 years ago.

If Harry Pope did it on a converted lathe, so can you.

Springs for these types of magazines can be made with music wire. Bend it ONCE around a form with the correct pitch and you’re done.

Gunsmiths make springs all the time.

If you need to make a flat spring, then get some 1070 or 1095 spring steel stock and learn how to heat treat steel. Hint: Learn how to use saltpeter salts heated to a liquid state for your tempering. Blues and tempers the spring all at one go.

You can make your own powder and primers.

This isn’t rocket science. It’s just chemistry, coupled with some stamping metallic production of small parts.

I’m not going to detail the steps involved. People who worry about these things should read up on primer chemistry - and powder chemistry. It’s not rocket science.

Black powder is even simpler to make - but more dangerous in large lots to deal with.

No, it isn’t. You’re simply not aware of what used to be cranked out on P&W machines when they did only one caliber, only one twist all day long. There were fewer machines in operation in WWI or WWII for all the rifles we cranked out then.

The reason why these dozens of barrel manufactures seem to produce so little is that they’re doing a blizzard of bores and twists, and all that one-off work slows them down. If you set up the sine-bar P&W machines to do 1-in-10, .308 barrels all day long, you’d crank out hundreds of tubes per day (and the machines have two spindles per machine, so the operator is prepping a second while the other spindle is working on a barrel). That’s pre-WWI machines I’m talking about.

The hydraulic tracers in WWII made this speed up. You lost the flexibility of the sine bar to gain throughput by setting the machine up to do one caliber, one twist, and then did the same thing, again and again and again.

There could be many more barrel makers, btw, for an investment of $100 to $300K for the tooling apiece. Modern CNC deep hole machines make this all go faster. Why don’t we have more barrel makers? Right now, the market is pretty well equipped. I can get barrel blanks in popular calibers all day long with a phone call. By buying a dozen of the same twist/caliber at a time, all in 1.250” blanks, I get speedy turn-around.

And those are premium barrels. Want to make things really boogy? Then go to one hole/one-twist barrels on a cold forging machine - ie, give up quality for yield. This is how Remington cranks out barrels.

The technology to make barrels isn’t secret.

I think making primers that worked consistently would be extremely difficult and dangerous to do at home.

I realize you can make potassium chlorate with bleach and salt substitute, but being able to salvage primers, prepare them for re-use and form the primer material into a useful and consistent product would take a lot of work, time and material.

I think it would be way more feasible to just resort back to a flintlock type of ignition.

Actually, percussion caps is as far back as we’d have to go.

Flintlocks require black powder, and black powder ground very fine. Very fine black powder is, IMO, more dangerous than priming compounds.

Yes, but it doesn’t have to be packed precisely like a primer and you don’t have to worry about each little anvil being in the right place. Chlorate primers are corrosive too. The tolerances for cartridges to operates consistently are a lot tighter, plus it would be very time consuming to produce enough by hand. If it were to come to not having any primers available, I imagine by then there wouldn’t be any smokeless propellant either. We’d end up going back to manufacturing our own black powder like mentioned earlier.

Smokeless propellant isn’t difficult to make.

Making a particular burning rate of smokeless propellant.... well, that takes some work.

But making something like gun cotton and then molding it - not that difficult.

It all seems like a huge problem to people who are liberal arts majors, who know nothing about manufacturing or machining... but there are enough of us out here who read poetry only as a hobby because we knew it would never pencil out a family budget. The barrier to making one’s own powder and primers is not as high as some would believe.

I remember a documentary of how the Brown Bess muskets were made, essentially wrapping flat steel around a dowel.
And a shotgun can be made damascus style with a higher grade of wire wrapped around the right size rod and either brazed or hard soldered. Or to just get a chrome-moly tube say from a roll bar.

Want to see a fascinating movie about making damascus barrels?

Here:

http://damascus-barrels.com/Movie.html

Saw this in a class on restoring damascus shotgun barrels last summer. The level of work that could be accomplished by some of the barrel houses around Liege, Belgium, with nothing but manual labor and forges is amazing.
