Shuty AP9 doing Rapid Fire - 3d Printed Gun - General

[media]https://www.youtube.com/watch?v=1W-eFOOy1aM[/media] Holy shit. It's strange to think that only four years ago, we only had stuff like the Liberator. Now we got semi-autos, and recently the guy working on the Liberator 12K, [url=https://www.youtube.com/watch?v=SMHeOot8fMA]has posted a video of the complete product[/url].

While impressive I still think 3D printed guns are fucking terrifying. Sure, you could argue about semantics in shit but at the end of the day some "bad hombre" is gonna start printing ghost guns in his basement.

This one is a lot more sensible than the other 3d printed guns I've seen. Not 3d printing your barrel is the way to go.

I'm sure this has been said before, but I can't help but imagine this kind of thing is going to cause gorvernment backlash against 3D printers. Which would be a huge shame, because seeing them help push open-source into physical objects is great.

Not that that's an excuse for the Government being shit heads, but still.

Like i said, I totally get it, but given the benefits of 3D printing above and beyond the small community of gun printers, I'd much rather that than a loon in a hardware store.

Its a huge boon for them, too. And usually its mostly related to reducing the costs and complexity of logistics in remote or difficult locations. not a lot of solicitations in any of the SBIR rounds yet for weapons-related 3D printing projects, thankfully.

Im wondering what kind of machine they used to make these parts, and just how much post-processing work is required. Its a bit asinine, though. Just draws lots of negative attention to 3D printers, all so some dickish bunch of dudes can be like "but i made a 3d printed gun, bro!"

You got folks in Mexico who are using it to produce stocks were their machine pistols, and in Australia it's being used to produce undetectable guns.

Why not put a proper stock on it? That cylinder coming out the back looks really uncomfortable.

[QUOTE=SamPerson123;52947258]Why not put a proper stock on it? That cylinder coming out the back looks really uncomfortable.[/QUOTE] Because if you put a stock on it, then it would be considered a short barrel rifle which requires a tax stamp for it to be legal. It'd be okay to put a stock on it if the barrel were longer.

that recoil looks awful for 9mm but then again i havent shot 9mm for 2 years now

Here's a PDF that shows you how to make a fully automatic 9mm handgun at home with tools and materials you can buy from a hardware store: [url]http://thehomegunsmith.com/pdf/Expedient-Homemade-Firearms-Vol-II-PA-Luty.pdf[/url] Pesky government won't let you buy ammo either? Here's a guide by that same guy on how to make ammo at home: [url]http://thehomegunsmith.com/pdf/EHF_Handgun_Ammo_Book.pdf[/url] I am not responsible for any lists you may be on after opening those links

[QUOTE=Zang-Pog;52946805]Banning 3D printers because of printed guns would be such a huge kneejerk reaction. 3D printers are [I]expensive[/I] and if somebody was desperate enough to get their hands on a firearm they could make one in their garage out of sheet metal / some pipe instead of 3D printing one[/QUOTE] It's still far cheaper to just buy a small used CNC machine, or even a basic vertical mill. The vast majority of tolerances on a gun are pretty loose, and the handful that are tight can be pretty easily adjusted down to size by hand with a little bit up setup using fixtures. Who cares if the slide has some minor unevenness in it? You don't need longevity for a close range disposable murder pistol. Hell, you don't even need rifling either.

That man should really be wearing some eye protection. You never know when even real guns might explode on you, let alone a 3D printed one.

Why is he holding it up to his shoulder like it has a stock? All that buffer tube is doing is giving him bruises. It's using a pretty low caliber so he should be able to fire it like a Tec 9 or something.

Seems kinda silly if you have to end up using a factory-made gun barrel.

[QUOTE=Naelstrom;52947848]That man should really be wearing some eye protection.

If nothing else. I wouldn't trust it either, though. [QUOTE=JoeSkylynx;52947607]No-no. This was just a reference to him talking about sheetmetal garage guns.

[QUOTE=download;52947838]There are plenty of people on youtube making rifled barrels with a small bottle jack press and some tool steel rod.[/QUOTE] Hand rifling takes forever. You can buy prefab barrels, or let the CnC chew on it. Only issues is that the mini mills don't have the range to get all the way down a long barrel, but if you're manufacturing illegal guns, your probably making handguns. With a CnC mill you can just buy stock, throw it in the machine, flip it after a bit, and have half a dozen lowers ready to go after a few hours. If you buy shit like the springs, you can make several functional guns in a single day. It's so fast because very few parts on a disposable gun need to actually be properly tempered. You can make a huge portion of a gun out of aluminum, which is dirt cheap, and carbide can cut it at several feet per minute. Hell, you can get away with milling ABS for stuff like the grips. High speed steel tools are inexpensive, and go through ABS like butter. Hit it with sandpaper, dip it in an acetone solution for a bit, and it comes out with a nice clean finish.

Just introduce registration for 3D printing devices? It's not something you could (at all easily) make at home.

[QUOTE=Occlusion;52949749]Just introduce registration for 3D printing devices? It's not something you could (at all easily) make at home.[/QUOTE] Might as well get registration for any tools you have since they can be used to create firearms as well.

[QUOTE=Occlusion;52949749]Just introduce registration for 3D printing devices?

[QUOTE=Zephyrs;52949733]Hand rifling takes forever. [/QUOTE] How about instead of dismissing my statement out of hand you go take a look. The fact you said "hand rifling" demonstrates you certainly have not.
