30-rd 3d printed AR (Stanag) mags

Anybody come across these yet?

Any ideas of the legality of these? Would the three printed parts be considered an "assembled" magazine, or would that require the magazine spring to be present?

If someone had access to a 3d printer, would there be a demand for "30 round AR magazine kits" without the springs included? If so, what would be the price people would be willing to pay for something like that? With the express understanding that it was up to the buyer to finalize assembly, which of course would including "pinning" it to the currently acceptable 5 round limit.

You might want to re-read the forum rules, i believe mag kits are a topic not to be spoken of.

That and a magazine in pieces, with the body unpinned was call a prohib device by a BC court ruling (I believe BC). Stupid as it is, having a unpinned disassembled mag could cause you problems.

Last article I read says they break after 50 rounds.

Given the current US political climate, it is possible something like this may become the only avenue for individuals to get 30 rounders anymore.

This just goes to show how woefully antiquated Canadian (and all) gun laws are. There are designs available for a printable AR lower, and just wait until the resin has a tensile strength comparable to aluminium! Then it'll be AR lowers for everyone!

It wouldn't be hard to modify the CAD file to include a pin like protrusion into the mag. Whether or not the polymer is strong enough is another story.

That thought fills me with happy.

Resin 3D printing is the wrong method to use for gun parts. DMLS, while more expensive, will get you desired results.

+10!

And when it's as strong as aluminum, I'm sure you could make more than just the lower

Good call, for those of you who don't own wikipedia:

Althought the build envelope is still too small:
"With a build envelop of 250 x 250 x 185 mm"

An AR mag is well within those dimensions. You could print almost any receiver within those specs as well. You realize that's 10" x 10" x 7.25" (14" corner to corner)?

They make bigger printers.

I have the schematics, as well as the AR-15 lower's schematics, but I did not do anything with those yet. I might print myself a down-scaled lower one of these day..

 

[lone-wolf]

I rather just buy normal AR magazines.

In 5 years time people will have serviceable mags and lowers that they can print from something they bought at Future Shop. Some people won't even wait for the paperwork, but they are bad, bad people. I lie awake at night worrying about the lack of paperwork, but what can you do?
It used to be that we bought videos, CDs and paper books. The idea that computers would put Blockbuster out of business was ridiculous.

One thing worrying for law-maker is that it used to be rather easy to prohibit civilian to own certain type of item which were not readily manufacturable. There was middle-men, put restriction, permits on the middle-men and you get the desired control done. As 3D-printing is becoming more and more advanced, one can create "disposable" prohibited goods on-demand, without middle-men. Even if the mags are currently breaking after 50 rounds, if all a criminal want is a disposable item, it's gonna do the job.

Anyway, that's just food for thought.

In that case, I'll be happy to see law-maker sweat.
Time to start going after criminals, not objects.

Print off some of those .22zip guns that were at shotshow. See if the world falls apart.

I love how everyone is going #### about 3D printers all of a sudden. You've been able to make your own guns at home for years. Hell, I can go spend $40 at the hardware store and build you a shotgun.

Some guy makes a barely functional plastic printed lower and even goes nuts.
