You can make an ar-15 receiver (legally the gun) out of plate steel from Home Depot and some spacers. The build is from the glory early years of the internet (90s?), so instructions are kinda hard to find. Why bother? CAD drawings for a $800 mill machine are available everywhere. Really, if you've ever held a receiver you'd realize how... primitive it is.
Europeans don't DIY guns because you're next to enough failed states to easily get fully automatic rifles. Why trouble your self with a building a semi-automatic when you can buy the full auto version? Except for Sweden and the UK. They prefer hand grenades and knives respectively.

This is not quite accurate. The [FGC-9](https://en.wikipedia.org/wiki/FGC-9) was made in Europe and has popped up in Myanmar. As I recall from the Popular Front documentary on JStark, the inventor of this weapon, other people were known by him to be making them in Western Europe.
I was being facetious to remind Europeans that their criminals have guns, better guns than criminals in the US do. The DIY scene in Europe is quite healthy, so of course someone will make a DIY gun.
