Means nothing, and hasn't since 1986 FOPA.

It repeals a law that "allowed" purchases in contiguous states, the need for which went away in 1986.

From 1968 to 1986 you could only purchase a handgun in your own state, or a long gun in a contiguous state, if both states allowed it, per federal law. Some states passed laws explicitly allowing it, though that wasn't necessary as long as your state didn't prohibit out of state purchases.

After 1986, the federal contiguous state law went away, which meant you could purchase a long gun in any state, provided your state did not forbid it.

This repealed the law "allowing" you to purchase long guns in contiguous states, and removes a useless law from the books, but does nothing to increase your rights or your freedom.
