You're making a couple of unfortunate assumptions. An already economically-weakened ConUS can expect the following: A domestic military with hardware that is failing left and right. A domestic military that has no ammunition because the "domestic security forces" bought it all. A domestic military that has no fuel. Foreign Fighters that are well stocked and equipped with advanced weaponry. The real "rulers" don't consider this to be their own country. They are citizens of the world. ConUS contains several million nuisances that would be best killed in an expedient manner, such as by plague or nuclear attack. In that kind of environment, it is less likely that having an AR or an AK in the attic will help the typical USian.
