I don't even know where to begin. I suspect I could buy these by the shipping container load and import them. But I have no idea what permits I need.
I also need to find funding.
Been doing research though. I think I could set myself up as an arms importer with the proper federal fire arms license. Still checking the legality of giving guns to people. I might have to sell them at a nominal fee (like $1) and ask for the $25 to run the federal background check
You'd need an FFL to import firearms legally, which involves interacting with the only efficient US government agency, the ATF.
