Gun rights groups and firearm industry leaders are launching a new legal effort to dismantle what remains of the National Firearms Act after President Donald Trump signed legislation Friday that eliminates excise taxes on suppressors and short-barreled firearms.

The forthcoming lawsuit, described by advocates as the “One Big Beautiful Lawsuit,” will argue that the NFA’s remaining provisions, including registration mandates and transfer rules, are now unconstitutional following passage of the Trump-backed “one big, beautiful bill.”
