Allright I voted collective, because initially I thought, as is thought by many, that the right to bear arms is afforded to the militia. That is correct, where people are incorrect is thinking that the militia means everyone.
In 1792, congress passed the Militia Act. This act defined a militia as all able-bodied white males, and it required that members of this militia own arms. This may seem a little dated, so I went in search of a more recent definition of a militia, and I found the following: According to the United States Code, “The militia of the United States consists of all able-bodied males at least 17 years of age and…under 45 years of age.”
BUT!
The second amendment clearly states: 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.
Hence, it is the collective right and indeed DUTY of all able bodied males aged 17-45 to keep and bear arms.
The federal government is to:
To provide for organizing, arming, and disciplining, the militia, and for governing such part of them as may be employed in the service of the United States, reserving to the states respectively, the appointment of the officers, and the authority of training the militia according to the discipline prescribed by Congress;
According to Article I, Section 8 of the Constitution
BUT! AGAIN!
It is ALSO the individual right of the people (and in the Constitution people is different than persons (citizens), people are everyone, slaves, blacks, women etc.) to keep and bear arms.
In conclusion, the second amendment guarantees arms ownership and the right to bear them to every single person in the United States. It provides specific collective and general individual rights to own and bear arms.
