Between 3-D printers and the “gun build” phenomenon, it’s safe to say that gun legislation battles are a sideshow. Despite the tendency of gun arguments to quickly concretize into opposing cartoons, the grand-scale issue of gun violence isn’t going away. It’s unfortunate that the conversation is so hard to have, all while the landscape is changing rapidly.

From an interesting Mother Jones piece:

The wooden and steel parts I need to build my untraceable AK-47 fit within a slender, 15-by-12-inch cardboard box. I first lay eyes on them one Saturday morning in the garage of an eggshell-white industrial complex near Los Angeles. Foldout tables ring the edges of the room, surrounding two orange shop presses. The walls, dusty and stained, are lined with shelves of tools. I’m with a dozen other guys, some sipping coffee, others making introductions over the buzz of an air compressor. Most of us are strangers, but we share a common bond: We are just eight hours away from having our very own AK-47—one the government will never know about.

The AK-47, perhaps the world’s best-known gun, is so easy to make and so hard to break that the Soviet-designed original has spawned countless variants, updated and modified versions churned out by factories all over the globe. Although US customs laws ban importing the weapons, parts kits—which include most original components of a Kalashnikov variant—are legal. So is reassembling them, as long as no more than 10 foreign-made components are used and they are mounted on a new receiver, the box-shaped central frame that holds the gun’s key mechanics. There are no fussy irritations like, say, passing a background check to buy a kit. And because we’re assembling the guns for our own “personal use,” whatever that may entail, we’re not required to stamp in serial numbers. These rifles are totally untraceable, and even under California’s stringent assault weapons ban, that’s perfectly within the law.
