> then they'd be classed as assault rifles and there'd be no regulation at all Well, they'd need to become a Type 7 and Type 10 FFL, subject to numerous regulations by the Bureau of Alcohol, Tobacco and Firearms, meaning every design would need to be subject to approval by the government only after they've ensured that it isn't easily modifiable by consumers. If you actually do manufacture an assault cannon, it's a destructive device of greater than half inch bore, meaning it wouldn't be eligible for civilian purchase at all, so your clientele would be limited to government. You'd be subject to paying applications fees, renewal fees, design submission fees, approval fees, etc. You'd be subject to routine inspections by the government, who can choose to disallow any product you'd like to make. Your clientele would be limited to government only, and you'd be subject to literally thousands of pages of regulations. Smugness aside, your strategy is very flawed, as adding firearms to your device would add immense heaps of regulation, and doesn't help avoid any, whatsoever. And of course, you'd still be responsible for all the regulatory hurdles of building a drone too.
