All provisions, all the time.
That is especially true about the Second Amendment, without which none of the other amendments would matter because a tyrant would have emerged a long time ago to seize power like the monarch our framers rebelled against if we didn't have recognition of our absolute right to keep and bear arms.
You may have read in recent weeks that Joe Biden's Bureau of Alcohol, Tobacco, Firearms and Explosives is already going after a class of guns, as it always has attempted to do. The ATF has announced a new rule stating that it will tax and regulate AR-15-style weapons and pistols, claiming authority to do so under the National Firearms Act … of 1934. First of all, this law is unconstitutional because it bans ownership of certain firearms, and that's not supposed to be allowed under the Second Amendment, which says our right to keep and bear arms "shall not be infringed." Period.
But that aside, a majority of House Republicans are vowing to oppose this new rule and the Biden administration's attempt to enforce, as The Washington Examiner reports:
A majority of House Republicans are vowing to kill a new Biden plan to tax and regulate one of the nation's most popular firearms for target practice and hunting, claiming it discriminates against disabled veterans and would make all owners "felons overnight."
