Answer: In some parts of the US, especially in far-out desert towns, home arsenals like this are the norm. There is really no limit on how many firearms or ammo American's can own. Machine guns are illegal, but can be permitted. If you have any semi-auto firearm, it's not hard to convert to a machine gun. Albeit, the firearm will fail apart fairly quickly from the abuse.
