AR Transfers in Montana
In Montana, private gun sales between residents are generally legal without an FFL dealer. Meet, verify each other’s Montana residency, and complete a bill of sale. For full documentation, GunTransfer ($50) handles the paperwork.
Note: A stripped lower receiver is the serialized “firearm” in an AR build — treated as a firearm under federal and Montana law. Upper receivers and barrels are not serialized.
