I've never understood the idea that owning a gun is somehow a safeguard against some whimsically hypothetical tyrannical government. It's like stockpiling for a zombie apocalypse; it isn't going to happen, but if it did you'd be screwed anyway. There are certainly legitimate reasons to own a gun, but that doesn't seem like one of them.
1) We can't exactly see the future, when it comes to these things.
2) Insurgencies have defeated, or at least stood up pretty well against, technologically superior armies.
3) Better to die free than to die a slave.
