Protect Our Military Families' 2nd Amendment Rights Act This bill broadens the scope of allowable firearms transactions involving active duty service members and their spouses. Specifically, the bill allows a licensed gun dealer, importer, or manufacturer to sell or ship a firearm or ammunition to the spouse of a member of the Armed Forces on active duty outside the United States. Current law already allows a licensed dealer, importer, or manufacturer to sell or ship a firearm or ammunition to a member of the Armed Forces on active duty outside the United States. The bill also specifies that, for purposes of federal firearms laws, a member of the Armed Forces on active duty, or his or her spouse, is a resident of the state in which (1) the member or spouse maintains legal residence, (2) the permanent duty station of the member is located, and (3) the member maintains a home from which he or she commutes to the permanent duty station.
