The history with actual cases of private arms being used to support or to resist government tyranny in the US can be generously described as "mixed".
It's also telling that so many instances like that, in the US and elsewhere, start with "... and then the good guys (or sometimes bad guys) seized a barely-guarded state armory". It's debatable how relevant private arms are to the resistance of tyranny anyway.
Foreign occupations are a whole other matter. When the call's coming from inside the house, plenty of your fellow "freedom-lovers" are helpfully using their liberty to liberate you from your liberty.
