You can buy whole kits to build your own, the capacity to control what is made with the is about as much as if you tried to ban someone with a table saw from building a birdhouse.

Pretty sure you could make a gun too, which is the point of this 3D printer thing

And like what about other CNC machines?

I like that California is on the frontier of many tech laws, but this and the age thing are particularly dumb lately

Nobody tell California about a nail combined with certain diameters of pipe, because guess what, those can become guns too.

I made an AR15 with a hobby drill press from Lowes at work. Give me a hunk of metal, a micrometer and a file and I can make you a gun.

Or worse.

I know that a Samsung teevee disconnected from the internet will try and use another appliances internet connection if it can. Gotta imagine this is possible in other devices, too.

I don't really get it other than changing its convenience and efficiency. Superglue and wall loops make stronger parts of multiple pieces than priting it all in one.

Maybe poor wording? I just mean their task is enormous to filter these parts in a way that actually targets them and nothing else and splitting pieces will invariably be the new technique for those people who are making them. The thing is when you're making gun pieces it's a disposable or sellable piece meaning they're likely producing multiple of the same models. They will easily adapt techniques that continue to work for them while our prints get filtered into that group despite having nothing to do with guns.

I also think we should be able to print whatever the fuck we want with our own devices, but even from their perspective it's not going to work. This seems like a handwave attempt at garnering plausible deniability from high profile cases of murder as well as sucking up to politicians and pretending they actually care about the problem.

Also in my original post I forgot this applies to CNC machines too, this is going to be a shitshow.

Yeah I’ve lived in CA for about 10 years now and have loved it, but the new laws they are passing are making it extremely likely that I’ll be moving soon. Especially with tje fact that we are either getting either Becerra who’s in Big AI and Big Oils pocket.

Neat, I would've assumed you'd need a mill or a lathe, not just a drill press. Kinda want to know how to do it myself, since I own the former but not either of the latter.

The upper reciever is the load bearing part on an Armalite, but it's also not the regulated part. The lower receiver is, and all you need for that is a box that holds the trigger components in vaguely the right place, a hole that lines up the magazine, a hole to stick the buffer tube into at the back, and some way to nail the upper receiver to it.

You could carve an AR lower out of wood if you were dedicated enough.

Last year I started maintaining a MAC address whitelist on the router: if I haven't added it, it doesn't get in or go out. No way in hell I'm putting any household appliance on the allowed list. While an appliance could technically still try to access via an allowed device, they're all phones and tablets and computers with slightly more robust security than the trust me bro levels of an IoT appliance.

Printer manufacturers won't make state-specific versions of printers. This is going to screw all of us.

If I'm not mistaken, this DOES cover ALL manufacturing devices, and if it doesn't, it will in the future

Can you share more info on this? I'm interested in the technical aspect how this is done, specifically which devices it uses?

For instance, say, a smart speaker, may have Bluetooth and WiFi, but I'm not sure any halfway comprehensive network stack I'd even implemented that could be used as a proxy, let alone autonomously remotely reconfigured to do so.

I don't own a gun, actually. Your assumption is bad and you should feel bad.

I am doing nothing but thinking about ensuring my ability to obtain one, should the political situation continue to deteriorate. That's prudent, not delusional.

The only one here acting obsessive and unhinged is you.

If memory serves correctly it was another Samsung device it was leveraging which makes more sense. There were other occasions where it had once been attached to WiFi for a firmware update, disconnected and told to forget the network, but attached again to it at least twice. Took the steps to forget the network again and then powered off completely. Subsequent checks show no further connections so far.

Actually ammo reloaded at home shoots better than factory ammo this is a known occurance. And guns put together with kits usually shoot better and have less problems than mass produced factory ones.

Guns aren't really that difficult to make. Hell that Japanese guy shot Shinto Abe with a gun he made himself although bit of a different thing because it used a battery to ignite the gunpowder but still the same idea.

Making guns isn't hard to do.

3d printed ones are a joke though. You can only use them a few times before they become even more dangerous and unpredictable. Anyone who wanted to use an actual firearm would never use a 3d printed gun.

Maybe one of those 200K metal 3d printers or whatever. But at that point it would be easier to machine the parts yourself out of metal. It really isn't as difficult as you seem to think it is to do that.

If they wanted gun control (which California already has a bit more of than other States) then they could pass a law doing that. This is 100% a surveillance law.

Next thing you know all stepper motors will require daily inspection before use by a robocop placed in every home.

It won't be accurate or be a long baller w/o a lathe to make a rifled barrel. Not that you couldn't mke a barrel with hand tools, it just would be very difficult.

And like others have said, only the lower receiver is the controlled item. You goto Brownels and can buy 98% of an AR w/o a background check.
