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.

Stop or I'll toot!

True. People have no responsibility for their actions. I should be able to steal peoples shit and use guns to commit violent crimes, because it's all someone elses fault. The government should be giving this guy tax-payer funded heroin!

... and I'm not suggesting this become normal or anything but.

If I could make a million drivers use 4-point harness safety belts, and drive wearing helmets and nomex coveralls, how would accident mortality be affected?

I'm not talking about frequency. A warm, cozy helmet cutting down on visibility and increasing drowsiness will probably increase frequency. But what about the injury severity and fatality rate?

I doubt we will ever know, but I've always wondered.

I also wonder if high-tech safety gear will cut into the GSA shrimp-eating party budget. Proably not, its practically free money.

This is why the term changed from "less than lethal" to "less lethal".

The fatality was Victoria Snelgrove, she was at a post-game riot and the round missed a guy throwing a bottle and struck her in the eye.

Not sure I would want a tazer the eye either.
