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.

Pleas do tell us the next time a birthday gets drive by'd by pipes and nails, otherwise, shut the fuck up dumbass.

zip guns, lets bring in slam fired shotguns.

Never doubt the ingenuity of man killing other men.

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.

Yeah, and that's why you don't have a meaningful social life. Because you obsess over building tools to kill people rather then spending your time learning how to build a better world.

Grow the fuck up.

[–] PattyMcB@lemmy.world 2 points 9 hours ago

I'm pretty sure that's already illegal in CA

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.

Guess I ought to go find a set of machining schematics.

[–] masterspace@lemmy.ca -1 points 4 hours ago* (last edited 4 hours ago) (1 children)

No, you don't. You can do literally anything productive with your life other than obsessing about killing tools.

[–] grue@lemmy.world 0 points 4 hours ago (1 children)

Please explain how I can "do literally anything productive with my life" when I'm murdered by MAGA fascists because I had no means to defend myself.

[–] masterspace@lemmy.ca -1 points 26 minutes ago (1 children)

Lmfao go touch grass. Youre alive so far because reality is not the internet, not because you own a gun and are statistically endangering yourself and your family with it.

[–] grue@lemmy.world 1 points 13 minutes ago

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.

Shovel AK is a thing too. There are stencils out there for it.

[–] TIEPilot@lemmy.world 1 points 16 hours ago

Gah how can I forget about the shovel AK????

[–] PattyMcB@lemmy.world 0 points 9 hours ago (1 children)

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

[–] masterspace@lemmy.ca -1 points 4 hours ago

Good, fuck Americans pretending like gun control isn't effective.

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.
