Make one yourself, it isn't that hard, crossbows been using bullets since the middle ages, mostly for birdhunting. So you'll have no trouble finding a simple sketch or photo on how to convert a regular crossbow.... without a 3d printer.

So they payed off a bunch of moron politicians and acted like they were worried about people smoking it and getting 'reefer madness' next thing you know it is illegal (was legal before 1910 or 20 I think. Can't remember exactly.
Your argument seems to come from http://www.idmu.co.uk/historical.htm or a similiar page.

Now it could be the hempleave ont he scales or the clipart but i don't see it as a reliable source, nor would I see any site of the kind as a reliable source. Not to mention that the reasoning is wel strange. Hemp fibres are not stronger than or better than anything else, Nylon which was on the rise pretty much killed the whole rope industry. Because nylon doesn't rot and thats a big deal. As for paper made from hem you're actually talking about... tada stuff (ass in cloth) back in the 19th century salvaged cloth from mummies was used for making paper, damned moralist banning graverobbing practices....
Furthermore the biomass of a hempfield vs that of an equal size of woodland is well pathetic. 30-40 years might sound like much but generally the area a papermill needs to supply wood is fairly small. The largest newspaper (paper) mill in europe had a radius of 100km and most of that is farmland and towns. Now theyre making magazne paper since regular paper can be made from recycled paper.

And just to clear up any messes.
Guns are not banned in Europe, they are harder to get but well in the northern countries gun ownership is common. Gun crimes are scarce though in the whole of Europe. In the old days reservists had their weapons at home, no glorified .22s but 7.62 battle rifles....
Criminals have a ready source of weapons, either by ordering different parts from machineshops or leftovers from the balkan wars. As for long range weapons: theres muzzleloaded cannons all over the place, might not be precize, but if you're a psycopath with an itch, the state provides.

I don't know why I didn't notice this before ... they aren't even using a standard AR-15 round, which is a much more powerful 5.56x45mm round. They are using a wimpy 5.7x28 round, which is a much lower recoil round that has about the same energy as a 9mm pistol round.

5.56x45mm 3100 ft/s @ 1303 ft lbs
5.7x28mm 2800 ft/s @ 400 ft lbs
9x19mm pistol 1300 ft/s @ 420 ft lbs

The FN 5.7×28mm is a small-caliber, high-velocity cartridge designed and manufactured by FN Herstal in Belgium.[7] It is a bottlenecked centerfire cartridge that is somewhat similar to the .22 Hornet or .22 K-Hornet.[7] The 5.7×28mm was developed in conjunction with the FN P90 personal defense weapon (PDW) and FN Five-seven pistol, in response to NATO requests for a replacement for the 9×19mm Parabellum cartridge.[10][11]

In 2002 and 2003, NATO conducted a series of tests with the intention of standardizing a PDW cartridge as a replacement for the 9×19mm Parabellum cartridge.[11] The tests compared the relative merits of the 5.7×28mm cartridge and the 4.6×30mm cartridge, which was created by Heckler & Koch as a competitor to the 5.7×28mm.[11] The NATO group subsequently recommended the 5.7×28mm cartridge, citing superior performance in testing, but the German delegation objected and the standardization process was indefinitely halted.[11]

Much the same way that the petroleum industry pushes to suppress alternative energy sources.

Actually, given that it was NBC News, I would personally go more with the notion that it was released (the news story that is) to fear monger and push their anti-gun, liberal, agenda. But that is another discussion for a different type of chat board.

Cool Idea. But if someone kicks in my door I'm going for my M&P 15 biggrin.gif

There is a big difference though...unless you are buying automated machining equipment you can't just go out and buy them and start making guns. It takes along time to learn the skills to use them.

You can go out and buy a 3D printer, set it up, load a design you got online, and press "Print". No skills needed. Even if it cost more to do I can see people going that route just because it would easier to do. Though, the cost of 3D printers are getting reasonable. For about $1500 you can get a decent one...for $500 you can get a not so nice one, but even that might do the job. I don't know if I'd pay less than $5000 for one that I was going to making gun parts with though, but thought is something I'd have to research.

I think you are seriously overestimating the whole "press print and viola, instant gun". Most people I know who own a store bought gun couldn't even fully DISASSEMBLE a gun, much less assemble one.

Even many of my gun friends come to me just to do a simple drop in trigger job for either guns after they buy properly machined Volquartsen trigger parts that are known to work and guaranteed. And yet you think people are going to download a file off the internet and "just press print"?

Well, that is still a hell of a lot easier than machining the parts buy hand. Assembly would be much easier to learn...a lot guns only have a few parts...parts that would be hard to make by hand, but easy to put together if you have them. A couple former military members that had to clean a gun every now and then could figure it out in minutes and those types of people are much easier to find then skilled machinists willing to make illegal guns.

Except you don't have to make an entire gun by hand, only a couple of parts (to make it fully automatic ... or to bypass the Federal control parts). They aren't that hard. Hell, a block of steel, a drill (not even a drill press) and a jig saw and hack saw and you are up and running. Total cost at Home Depot ... $100 ... vs how much for a 3D Printer?



Drop in auto sear for an AR-15 to convert it to fully automatic.
