In the US, many pressure-bearing components such as barrels are not controlled parts. You print the frame or lower receiver, then use normal parts that are compatible. This has been done for MP5s[1], AKs[2], Glocks[3], and even AR-10s in big calibers like .308.[4]

Even if barrels required as much effort to get as a complete gun, there are already designs that use no gun parts. The FCG-9[5] is the most popular one. It's actually pretty easy to ECM your own barrel at home. Hundreds of people have built guns like these using zero gun parts.[6] They're reliable and accurate enough that they're being used by Burmese rebels.[7]

I don't understand why some gun rights advocates point out that the current regulations make no sense for 3D printed guns. I think they think that this demonstrates that the rules shouldn't exist... but I think the response that they're going to elicit is a push for controls on barrels/slides/uppers/ammo.
