@critical @icedquinn I remembered a documentary about group of bandits operating in soviet city, who were thought to be foreign agents, because they used firearms that was nearly impossible to buy or smuggle, until they were catched and apparently they were just some people who were smart enough to design their own guns and make parts in a basement and on a local factory equipment (they asked some help from fellow factory worker friends, just disguised parts with adding additional stuff on them so it wasn't obvious that it's a gun parts)
