No, it’s a right because it was deemed necessary to the security of a free state. But the individual right to bear arms was meant to be as part of a “well-regulated” militia, not simply as “everyone can have whatever weapon they want.”
Even our current very loose and I would argue inaccurate interpretation of the 2nd does not contemplate the idea that private citizens should be allowed to own tanks or heavy machine guns or SAMs without a ton of oversight.
And of course none of this touches on the elephant in the room which is the rather obvious fact that if we take originalism seriously, then we have to concede that Madison’s conception of the 2nd as being “necessary to the security of a free state,” no longer applies since he was specifically concerned with large-scale civil insurrections such as Shay’s Rebellion or slave uprisings, and we know very well that militias can play no role in putting down such incidents in a modern context, and to the contrary, generally only serve to exacerbate tensions and escalate violence.
