I don't give a tinker's damn how much money you have and how much you're willing to spend on firearms. Not even the Koch brothers have enough money to buy enough weaponry that should the feds ever decide to come after them, they'd have more than the equivalent of a cap pistol in a nuclear fight. If you buy a firearm to "protect yourself from the gummint" then all you're doing is deciding which firearm you want to be holding when you're killed.
