“The right of the people to keep and bear arms shall not be infringed; a well armed and well regulated militia being the best security of a free country; but no person religiously scrupulous of bearing arms shall be compelled to render military service in person.”

That is to say that all have the right to be armed and trained in the use of arms, but none can be compelled to join the ranks of the military -- militia or otherwise. So we have the right to possess arms whether we wish to serve in the militia or not.

Infringement examples: My handguns are registered (for eventual confiscation); I can't buy a machinegun without government permission (FFL, costly fees, inspections at any hour, etc.); People in California can't own .50 caliber guns; Requiring a CCW to "bear" arms; Felons who have served their time are unable to own guns, even for self-defense (if they are still dangerous criminals, they should still be in prison)...

Duckman's time warp messed up a bit; you know who else, the one who claimed that the exclusive author of the Bill of Rights was Jefferson; the same as the Decl. of Inde. when I saw a book by Paine titled such.
