Federal authorities have ceased enforcing major registration and tax-stamp rules for short-barreled rifles, short-barreled shotguns, and suppressors after an October 9 ATF policy that followed a decision not to appeal a court injunction. Officials in Florida, Idaho, and Mississippi have treated federal paperwork as no longer required under current policy, while Montana lawmakers announced they will seek 2027 legislation to drop related state limits.

Maryland police advised that state law still requires federal registration before making, buying, or transferring those short-barreled firearms. A Florida circuit prosecutor also told local agencies that missing NFA documents alone should not justify detention or arrest. Machine guns and destructive devices remain covered by the federal statute, and a later administration could resume enforcement.
