Originally introduced and passed in Montana, the FFA declares that any firearms made and retained in-state are beyond the authority of Congress under its constitutional power to regulate commerce among the states.
Since its passage in Montana, a clone of the Firearms Freedom Act has been enacted in Tennessee, and has been introduced in the legislatures of Alaska, Texas, South Carolina, Minnesota and Florida. Legislators in many other states have announced that they will introduce FFA clones when their legislatures next convene.
The FFA is primarily a Tenth Amendment challenge to the powers of Congress under the “commerce clause,” with firearms as the object – it is a state’s rights exercise.
