So let’s take a look at that pesky Bill of Rights thing again. The U.S. Code, in all its majesty, actually addresses an important Second Amendment issue:

a) The militia of the United States consists of all able-bodied males at least 17 years of age and, except as provided in section 313 of title 32, under 45 years of age who are, or who have made a declaration of intention to become, citizens of the United States and of female citizens of the United States who are members of the National Guard.

(b) The classes of the militia are—

(1) the organized militia, which consists of the National Guard and the Naval Militia; and

(2) the unorganized militia, which consists of the members of the militia who are not members of the National Guard or the Naval Militia.

That’s right — if you’re an able-bodied male between the ages of 17 and 45, you’re automatically a member of the “unorganized militia” or “reserve militia” — something quite distinct from the National Guard. Which means that you are expected to come to the defense of your country should the regular Army be unable to function or the situation require an instant first response. And in order to do that, you have to have and carry your own gun. If that doesn’t settle the argument about the “right to keep and bear arms,” I don’t know what will.
