In english, what does this section from 18 USC mean?


Sec. 927. Effect on State law

No provision of this chapter shall be construed as indicating an intent on the part of the Congress to occupy the field in which such provision operates to the exclusion of the law of any State on the same subject matter, unless there is a direct and positive conflict between such provision and the law of the State so that the two cannot be reconciled or consistently stand together.

Means the federal government is not reserving the right to regulate firearms to itself, and any state and local ordnances are still valid, provided they don't directly contradict the federal legislation.  Basically means states and lower level governments are free to enact laws more restrictive than the federal ones.
