> 2) You are not allowed to transfer or sell them.

It'd be perfectly legal to transfer such a thing to say... a gun 'buyback' (government or privately run): https://www.thefirearmblog.com...

You could even built one and hand the result to your spouse or a friend (so long as they are not otherwise prohibited from owning and no other laws restrict casual transfers/gifts of that sort of firearm).

You run risks when you are making so many that the BATFE decides you are now in the business of building them.

What is the magic number? No one knows, just like no one knows exactly how many firearms a private seller can buy/sell at a gun show before they need to become a FFL. It's very much at their discretion.

I'd bet money that selling a few of what you made (outside of a buyback) would probably make you look more like a manufacturer as well.

"Thus, 14289 (76%) participants were included in this analysis. 1150 (9%) individuals had concentrations of lead in blood below the level of detection and had an amount of 07 g/dL (0034 mol/L) imputed."

So, for 9% of those still alive whose Pb blood level was below the level of detection they "imputed" their Pb level at 0.7 micrograms per deciliter.

"Our findings suggest that, of 23 million deaths every year in the USA, about 400000 are attributable to lead exposure, an estimate that is about ten times larger than the current one."

"suggests"? A British journal citing work by a Canadian research team about children in America and their findings, claiming an influence 10X larger than previous research, are a "suggestion".

The Lancet has taken huge detours into politics in the last few decades and this appears to be another side jaunt. What issue in American politics could they possibly be trying to influence? Obama shut down the last remaining lead mining and processing plant in Missouri in 2013, and by E.O. outlawed importing Lead into the country.

You have NO IDEA how effective the finger scanner will be.

Well let's see: if the battery is dead, that effectiveness will be a big fat ZERO.

I'm going to have to charge my gun? What, with a USB cable, or the new QI stuff? How about a Lightning or USB 3.1 port? How about a 120V (or 220V in Europe) plug? Or is it solar?

Are the indicator lights showing the charge, or beeping if it's low (like a smoke detector), or what?

Forget about the very important fact of sensor fingerprint detection ratio (which damn well better be 100.0000% even if it's completely covered in mud or blood), what about the battery and connecting wires? They'd also better able to completely handle water, physical shocks, and mud. IP68 or don't even bother.

Do I need cables to jump start it? Are they Duracell or a no-name brand? Physical package? AAs? 18650? CR123As? WHAT ABOUT BATTERY LEAKAGE from cold or heat? What about adding RAM (EPROM swap actually)? What about the add / delete / change user device reset dance? Or increase sales with single-user device obsolesce: "Sorry, this gun can only be programmed a single time. You can sell it but it won't fire without your finger going with it."

This is NOT a problem looking for a solution. This is stupidly. A gun is a tool -- it fires only when you pull the trigger; it doesn't when you don't. Anything else is a manufacturer defect. That the RIGHT person is pulling the trigger is stupid. If you've had to actually pull a gun you've already lost the battle, best you win the war by shooting. NOW. You only aim at what you want to kill -- otherwise why the hell are you even aiming at it? The ONLY delay should be if you are not aiming at the "right" spot and need to adjust. If you have a backup person, they'd better be able to use it as well. And if you let the wrong person get hold of it ... well you just screwed up badly, didn't you? "Oh, well at least the bad guy can't use it to shoot you." YES he can, he reaches over, grabs your hand and places it on the gun. It unlocks and now everyone's happy again! Well, almost.

Done correctly, electronic guns can reduce points of failure, not increase them. You’re still going to want to use lithium primary batteries, or some kind of float charger in your gun safe, but after 10 years unmaintained, conventional firearms are a little less reliable than they used to be, too.

Home-made guns almost never happen? Like the 10% of captured guns in Australia ??

And if you're talking improvised firearms, it's even easier. Hell, there are videos on YouTube showing you how. . .

Yep.
Totally the same: http://www.thefirearmblog.com/...

Actually, there is such a thing as an AR-14 -- it's just so incredibly rare most people think it doesn't exist.

See http://www.thefirearmblog.com/... for one interesting article on it.

(But I agree, the original poster probably meant AR-15)

I hope you are kidding.

1,600 hits, 2 of which were actual gunshots...

In August 2012 West Midlands Police said of 1,618 alerts produced by the system since November 2011, only two were confirmed gunfire incidents. - See more at: http://www.thefirearmblog.com/...

That is a silly comparison.

Your conclusion is nominally correct. You would be hard-pressed to do a lot of damage with a .22, but you could certainly do critical, lethal damage. Both tend to leave clean holes, but the .22 tends both to leave less of one, and to penetrate less.

Okay, I'm sorry for being all snark and no informative on my previous post. T-worx, Wilcox, and even NATO are working on doing this - at the rifle scale. There's not much excess space in the average handgun, and anything you stick in front of the trigger guard that's big enough for a respectable battery is also probably big enough to be considered a forward pistol grip. It's the work of a half a second to attach a vertical foregrip to many pistols - and also a felony. Bonus: the organization charging with enforcing that law has a great deal of latitude to interpret the law, plus enforcement powers and have consistently demonstrated a short fuse and questionable intellectual honesty. (Did you know that if you attach a ring to a string, it's legally a machine-gun part?)

Not only are you trying to solve a non-trivial engineering problem, you're trying to optimize for both battery life, cost, and bulk. It's no wonder they're sticking to electrifying rifle-sized platforms, when you think about that. One more thing - you're trying to do it without accidentally committing a felony. Much easier to sell something like this to the Army, who gets to ignore laws aimed at private possession of weapons - but to do that you really need to find a way to improve significantly on the mechanical firearm action, which is awfully close to a solved engineering problem by now.

whose idea was it to use metal detectors as gun detectors? Time & technology change... and detection methods must change with them.

If non-metallic guns were truly viable, they would have been used 20 years ago to sneak past metal detectors and kill judges and politicians and airplane pilots. Plastic manufacturing has been around for a long time, the only thing 3D printers do is reduce the cost. There are well-funded spy agencies and a few individuals who would have paid hundreds of thousands of dollars for a single gun. And yet none has materialized: [1] [2] [3]

Of course calm doesn't mean stable but the idea that taking your kid out target shooting instantly trains them on how to be a mass murderer is absolutely ridiculous.

And "assault rifle" is an absolute bullshit description which basically amounts to "this gun looks dangerous" there's nothing in the 1994 Assault Weapons ban that really bans anything functional in the guns. Basically its the gun equivalent to trying to reduce speeding by banning people from owning cars that are red, orange, yellow or have flames painted on.

For example this gun: http://www.thefirearmblog.com/blog/wp-content/uploads/2012/01/uzi_pistol_2245800_rs-tfb.jpeg

Looks dangerous, but really its just a semi-automatic pistol firing a .22LR cartage. Such a thing would be banned under the terms of the '94 ban. However, http://cdn2.armslist.com/sites/armslist/uploads/posts/2012/07/13/470085_01_browning_30_06_bar_640.jpg would not be banned, despite the fact that a 30-06 has a whole lot more energy behind it and could do a whole lot more damage: http://3.bp.blogspot.com/_Z_e7UMpSDh0/S-x2DjLi22I/AAAAAAAAE6U/LbntDs3L6UU/s1600/comparisonlabel.JPG

If anything, hunting rifles are -more- dangerous than so-called "assault weapons" because they've got more power behind the rounds. They are also far more accurate.

It amazes me how much of a knee-jerk reaction people have when it comes to guns. Especially from people who have never really shot one. Real guns are quite different than those that Hollywood portrays. Shooting is completely different than that which Hollywood (and video games) portrays.

That's interesting to read. I've only ever come across the material as part of industrial equipment (eg. a big ball of the stuff in a crude oil valve), but brought up the knives to provide an example people could better understand. I'm glad now that when I was thinking about getting some PSZ knives online that the price scared me off.
I remember reading somewhere about someone making a gun barrel out of PSZ a few years back but don't have a web link. Google provided this but I'm not really sure if this thing with a PSZ based barrel ever actually worked:
http://www.thefirearmblog.com/blog/2011/10/05/what-happened-the-the-mythical-undetectable-plastic-gun/

...and if you want to invade there's an app for that.

There really is an app for that.

Well you can just get the software. i think it has several rifles that it supports. There is also another one that is $4.99 where you can make your own profiles for whatever rig you have.
