A new California law was just passed which made "ghost guns" illegal. He was involved in ghost guns, at some level. It wasn't illegal before. Now it is. So now is when he got the boot.
CA doesn't control the Internet
Plus he had none of that content on his channel save for one video on the history of printed guns which got him dinged just over a year ago and he removed it
The 1968 Firearms Act encased in law the right to make your own firearms and made it illegal to sell them So, Printed or Milled it was always illegal to sell legally made homemade firearms
Yep, if you're a criminal making ghost guns to commit crimes because you can't pass a background check to buy a gun (and then scratch the serial number off), then it's already a crime for you to have that ghost gun because you're a prohibited person.
Requiring a serial number changes nothing and only affects nerds, not criminals.
But for that you need all the parts, including the gunpowder. And for the gunpowder you need a special permission for handling explosives, at least in my country. So you just move into areas of even more difficult to procure things. it seems far easier to just buy a gun and ammunition somewhere else and take it over the border into California.
If 50 pounds or less of commercially manufactured black powder is being purchased, and the powder is intended to be used solely for sporting, recreational, or cultural purposes in antique firearms as defined in 18 U.S.C. 921(a)(16) or in antique devices exempt from the term "destructive device" in 18 U.S.C. 921(a)(4), no form is required. However, if the black powder is being purchased for any other purpose (regardless of quantity), the purchaser or other transferee must possess a federal explosives license or permit.
Federally there is no law that says you can't print and carry your own gun, no serial number required.
However several states have strict laws and there are weird caveats. It has to be for personal use, cannot be sold or transferred and under the Undetectable Firearms Act any firearm that cannot be detected by a metal detector is illegal to manufacture, so legal designs for firearms such as 3d printed guns require a metal plate to be inserted into the printed body. Also online posting of plans for 3D-printed firearms require a license under the Export Administration Regulations issued by the Bureau of Industry and Security.
So if you design your own gun, or get one from a company that has an export license, print it and then ensure that it has enough metal in it to be detectable... Go for it, should be legal.
Almost all of them still use metal parts that can be x-rayed and still have barrels that leave ballistic fingerprints on bullets. Serial numbers don't make something GPS-tracked.
Untraceable in terms of ownership? There is no national firearm registry. Guns bought from FFLs require a NICS background check that is stored in an ATF database (of questionable legality), but private sale guns often don't require NICS so the database isn't an accurate registry of gun ownership.
And criminals scratch off serial numbers anyways.
And add on that any laws requiring serialization of privately-made firearms are only affecting nerds, not criminals. Criminals that are making guns because they can't pass a NICS background check will continue not adding serial numbers - because they're criminals.
Sounds about right, I remember watching his content on that regards awhile ago when I was interested in the topic, before my state made them illegal that is.
Basically if you wanna operate a company hosted on servers in a specific place you're going to have to abide by the laws of that place. Or if you want the ability to do business in a specific place you'll need to abide by their laws even if you're not from that place.
3D Print General had one video where I recognized an AR-15 lower being printed in the background. The voice over was on the printer or filament (I forget).
Hoffman Tactical is still on YouTube. I was made aware of this channel when researching CF Nylon. HT has several promotional videos of his 80% printed AR rifle, and long discussions about which filament to use for which part of a rifle.
