Just ban the sale of gun parts in California.
Obviously they didn't ask how ghost guns were made, but absolutely no one on the streets of Cali is using something like an FGC-9, they're printing Glocks and AR-15 bodies and then filling it with completely legal parts (I think they're legal. Not sure. Not in Cali)
Anyways, glad they are required to release guidelines for a detection algorithm at least, but its bullshit they can make these requirements WITHOUT a proof of concept at least!
Gun parts are things like 'spring', 'metal tube', 'wood', and 'pin'. Good luck with this ban. If you go through with it, half the stores in the state will be gone, every tradesman will be gone, and almost every product will be gone as they contain gun parts.
Guns have been around for hundreds of years, and it is because they are pretty damn simple. 'Just ban the sale of gun parts' is a complete non-starter.
No, gun parts are "Glock Upper receiver" and "AR-15 Bolt Carrier group"
These are precision machined pieces that fit within such tight tolerances that fucking it up is how you blow up your hand.
3D printed guns work because you can 3D print lower receivers because it doesn't actually do anything with containing an explosion.
It relies on off the shelf parts of guns being available.
Now could they be printing a fully DIY gun like a "Fuck Gun Control 9MM" aka an FGC-9 and build it out of tube, spring, wood. Yeah, sure.
But that IS NOT the majority of ghost guns and those are such terrible guns that their intended use is as a modern Liberator: a gun you use to kill someone with a better gun and take that gun.
Using a FGC-9 in California gang violence is how one gets shot by a flock with a switch. Aka, a better gun.
Source: I live in a state where its completely legal to build my own guns.
"Firearms precursor parts" are meant to be only sold at licensed dealers in California, but I'll let you guess how simple it is to sell something that isn't on the list of "precursor parts".
Also, you're supposed to register any weapon manufactured yourself in the state.
Interesting. So shit are they find FGC-9s in Cali?
Okay, now define what a 'gun part' is.
