Funnily enough, the second amendment isn't that cryptic. It says that, in order for the states to remain free, they need their own militia made up of the people, and that militia needs arms, thus the federal government shall make no laws inhibiting their ability to acquire said arms.
Ironically, the laws we have on the books are technically unconstitutional.
Just a nitpick, it doesn't say the federal government shall make no laws, it basically says nobody will. Precedent after the fact limited the scope of the bill of rights to the federal government until the passage of the 14th amendment, but the wording of the amendment itself placed no such restriction.
