I'd say they've traditionally been made out of metal because it has taken polymers a while to catch up with metals in certain applications. I'm sure the Magpuls are injection molded with a superior polymer than most 3d printers can utilize.
Someone with an injection molder can make them too. Requires a metal mold that takes machining to manufacture. Springs are still metal (but springs are easy to make)
Yes, a motivated person can manufacture all the parts of a gun. Barrel, magazine, etc. That person would be highly employable in some sort of metalworking position. They are not likely to be a threat to society. Bullets, sure they can be made. If you are a chemist, or know enough, you can even make your own propellents. But the US is awash in guns (and ammo), it is far easier to steal or purchase than make one. As long as there are military arms, police arms and the like, there is a supply line that can be corrupted and diverted.
A Sten submachine gun would be a good starting place, as far as ease of manufacture.
Yeah, and I can make an AR lower receiver in a Bridgeport style mill. Tough to get the forgings at the moment, would have to make it from solid.
WireEDM the magwell and the rest is pretty much doable in a drill press.
Barrels are the really hard part. Luckily there are oodles of barrel makers and plenty of supply. AR uppers can be mail ordered (they are not classified as firearms themselves, unlike the lower receiver)
Metalsmiths have been making guns forever. Most of them buy magazines, because they are too cheap to make yourself. Same with barrels.
The problem with the 3d printing is that they are not using clean slate designs that are appropriate for the materials used in the 3d printer. Copying something made from metal out of plastic isn't usually a good way to make a successful item. (I realize there are 3d printers that make metal objects, they are even more out of reach of the masses)
You are right, you could hack together a magazine like you describe, but production magazines are stamped in presses using dies. All of this can be made by someone skilled in the metal arts, with the resources. I've heard that a FN FAL magazine uses something like 10 different dies to get the body metal formed to shape. And another set for the follower and bottom plate.
Magazines are simple devices, but actually producing quality, reliable magazines is out of reach for most people. With this, someone with access to the appropriate 3d printer (which is also out of reach for most people) can make one.
Yeah, it isn't like Netgear hasn't released their own dog turds. I think it is like everything else, when your shoving that much product, some turds slip through.
There is some plausible reasons for burying the planes, but to think that eyewitness locals would not dig them up for scrap in the intervening years is stupid.
For extra smooth slip n' slide? Don't want it on the inside, the thing will slip right off. Or maybe just put the coating on the outside and also just the inside tip.
It's not hard to convert an automobile engine accustomed to leaded gas to unleaded. Getting a catalytic converter to work with leaded gas is very difficult.
Aviation gas is still leaded. I think the aviation market is so small (comparatively) that the EPA is not so concerned, and the FAA doesn't want to go through the legwork to make piston aircraft unleaded capable.
Ok, going over the article a second time, this game appears to be a more intellectual venture into interactive commentary on war? An interactive performance art piece?
My previous comment above still stands, but isn't directed towards this particular game in question.
I'm waiting for the real life mass shooting involving multiple armed citizen "good guys" that, once the mass shooting starts, they mistake each other for the mass shooter and add to the body count. So far, we've had a few mass shootings with armed citizen "good guys" engaging or attempting to engage the shooter. I don't believe there have been more than one "good guy" shooter involved (aside from law enforcement).
As a personal aside, I do not concealed carry. Even if I were too, if I were to encounter a mass shooting in which I'm not directly being targeted, I'm pretty damn sure I'd do my best to get the hell out of the mass shooting scene to safety. If that makes me a coward, well, I guess I'm a coward. If a mass shooter is engaging the public at large, he'll often have a superior arrangement of firepower due to his advanced planning. I don't want to engage that type of shooter with a mere concealed carry type pistol (I don't ever want to engage and armed assailant, if I can avoid it).
Can this not be framed into a category of obscene material? This and violent video games? I know this raises touchy First Amendment issues here in the US.
Obscene material alone is considered a touchy subject, child porn is generally universally accepted as obscene and not protected by the First Amendment. The act of producing it in the US and most of the world is criminal.
With regards to this particular circumstance, I feel that a violent videogame about a current violent actual real life tragic event is no worse than the actual real life events unfolding in front of us right now in real time. The fact that some people are using this event to cash in is crass.
Considering she served on the accident investigation board of the Columbia accident (2003), and then died this year (2012) of pancreatic cancer, I say that there is no sick irony in naming this crash site after Sally Ride. Is there some other crash site named after an astronaut that perished in a crash?
That wasn't a crash helmet, it was an aerodynamic faring attached to his head. It stuck out like two feet to the rear of his head. Not the same as a crash helmet.
Not only that, he insults the culture with the bit about poor families "promoting" their women to rich guys. It might be true, but is now is not the time to be talking about it? The guy certainly feels the need to justify his relationship with women.
The computer was fitted to the instrument unit (IU) that was on the S-IVB stage. That computer controlled the stack up until the stage (S-IVB) fitted with the instrument unit was jettisoned. (There abouts anyway, I'm sure there was a "hand-off" to the Apollo guidance computer). Technically the earliest of Saturns had no IU, but they were not manned flights. I believe this was due to the IU still being in development. Here is more on the IU:

Check your facts, the USA is a democratic republic . It is not a pure, mob rule democracy. And that is a good thing.
Ever consider he may not have tenants because no one would want to have 1,000,000 watts of light pouring into their office each and every day?

Mod this guy up. According to the website with the data, it is a map of those with pistol permits.
Not gun permits, but pistol permits.

None of the Saturn series rockets were "dumb". The booster had its own guidance system independent of the spacecraft's guidance system.
