all the weapons were registered with the exception of the rifle, which reportedly didn’t have a serial number because it was purchased in parts, an FBI spokesperson told The Times.

Unless this was an 80% build, pure BS - and even if it was, still misleading.

You can't legally buy a finished, unserialed 80% receiver.

The FBI is lying and the Times is stupid. So what else is new?

I wondered about that, though my thought was the skill necessary to build it. Also the “registered” comment, CA doesn’t register firearms, do they?
