The 2nd amendment is clearly grouped in the amendments that attribute rights to INDIVIDUALS. The 1st amendment has religion speech, press (non-government right), petition, and assemble, all individual rights or at least not rights of the state. The 3rd amendment is the right to not have to tolerate quartering of soldiers in private houses (one trampled on during the war of northern agression) during times of peace or war; another individual right. The 4th amendment is the interdiction of unreasonable searches and siezures and the requiring of warrants; yet another individual right. 5th - Self Incrimination - individual. 6th - fair and speedy trial - individual. 7th - trial by jury - individual. 8th - No excessive bail and fines or cruel and unusyal punishment - individual. 9th - that those rights set forth in the constitution are not the only rights of the individual. And the 10th LIMITS the power of the federal government - this is the only one which could be construed at the state level as it clearly states "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people." but also refers "to the people" which infers the individual. The bill of rights are oriented towards protecting the individuals rights, not those of the state.

The second amendment, as passed by the House and Senate reads "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed." Note that "people" is not capitalized. Throughout the Constitution, whenever you see people in lower case, it has been interpreted as being the individual. Here is no different. All the elimination of the second "to" does is imply that keeping and bearing should be held together. Basically, it means you can't just grab you neighbors gun any time, even with his permission. It must be your gun. But it doesn't provide for any prohibition on your purchasing any weapon of your choice. That is the only gun control the constitution allows for. In order to bear the arms, you must be the keeper of the arms. Nothing more.
