So guns are decreasingly used for robberies.

That wasn't the point you were trying to make, was it? Because I just counter-cherry-picked you.

take out the 5 most left-wing anti-gun cities and we around the 5-10 safest countries in the world.

Ahh.. Mexico. Where private gun ownership is forbidden.

license = permission slip.
a citizen doesn't need a permission slip.

registration = list of houses to raid.
a list that has been used time and again by totalitarian governments, including GB.

laughing stock? you live by government permission slip... like I give a fuck what you think.

It depends how it is measured.

If you take polls relying on self reporting, then yes, the numbers are slightly declining.

If you take the number of NICS background checks then the numbers are up.

Most states have no registration at all. I can buy or sell a gun to another private citizen I don't have to tell anyone, as long as it's not an NFA item. I can even mill out my own un-serialized rifle that no-one knows about (talked about in a previous /. article on 3d printed guns)

Even the number of NFA classified items (machine-guns, suppressors, etc) are up.

If only 1 in 5 of the NICS checks resulted in a sale, then gun sales from stores alone outpaced the us population increase.

The gun industry actually sailed through the recessions like they never happened, and gun-industry jobs grew like 30%. People will be retiring off the money they make selling ammo with crazy markups.

My state's concealed carry program has been off tha hook as the kids say.

the police don't actually have to protect the citizens.

this is worth watching.

it is also worth noting that the US is safer now than ever before.

on the other hand, the real deal is there are a surplus of military equipment that can be useful in all kinds of scenarios. the high clearance of an RG33 would be good in a flood, and good for active-shooter scenarios. might as well snap them up if the price is good.

How about a 70% milled lower? 32%? A solid block of aluminum?

When shapes are outlawed, only outlaws will make shapes.

To be clear, you said selling them. In the US, selling your home-made guns without a manufacturing FFL would also get you put in jail.

Worse than that.

You could 3d print several other 3d printers, each could then be used to construct one part of a giant robot. The giant robot could then learn how to 3d print some plastic yoda heads until the materials were exhausted.

Good luck lugging a giant robot, 7 3d printers, and 4000 plastic yoda heads to the airport parking structure, sucker!

the upper of an AR platform (based on the Stoner design) mounts the barrel and houses the bolt and bolt carrier.

the lower has the magazine well, mounts the trigger mechanism, and houses the buffer and buffer spring housing (around which, the stock is mounted).

the chamber is an area of the barrel that holds the cartridge for firing.

I think you need to go shooting with your friends some time.

Those of you who live by government permission slip will also not have access to 3d printers that can make guns.

The BATFE designated a shoe lace as a machinegun because they can. Your government will do whatever it wants to take from you whatever it wants. 3d printing included.

I imagine the wizards at IBM in the 1960s said the same thing about computers in the homes of the unwashed masses.

There are several commercially successful makes of polymer AR lowers.
In AR-land, the serial is on the lower.
A 3d printed lower gives you the ability to print a non serial numberd AR. Which is legal (US federal. YMMV) because home-made guns don't have to be serialized.

What is really important here is:

us /. nerds, being geeks who are almost always involved with computer technology of some sort, in capacities professional, hobbyist, or both, immediately become defensive and insulting toward anyone who talks about technological devices in a negative way.

Never mind the claim, immediately condescend and attack anyone suggesting that electronic devices may not be the optimal solution for every situation!

Bonus: the teacher's union angle! The few right-wing of us (which is me, actually) can immediately jump on that one too. These fucks don't care about kids! There's no way professional teachers know anything about teaching kids! Because they are a teacher's union, they must be speaking on behalf of the anti-ipad wing of the Kremlin!

There is no way that parking a kid in front of a screen for several hours a day can have any ill affects, you socialist pinko union teacher!

In the early days of the FBCB2 systems that were put into the Stryker vehicles, the computers talked via EPLRS and could get position via GPS or EPLRS (but never did). In some class, the contracted trainer explained that the EPLRS was sort-of like a portable, land-based LORAN radio triangulation setup that was basically got forgotten about when GPS became the new hotness, about the time the PLGRs (AN/PSN-11) were good enough to replace the SLGR that no one wanted to ruck.

The serial number on my striker was 8. As in something like 000008.

Are we saying Global Positioning System, capitalized and considered a Proper Noun?
Then, no.

Are we saying global positionin system, a generalized term for systems that give you position data on the globe?
Then yes.

LORAN, EPLRS (when used as it was actually created for instead of a mesh data network), VORTAC, and probably many other systems were all generic positioning systems.

If the earths magnetic field moves (and it does), then won't this system also be affected?

So open it gradually.
