Repealing the tax provisions may have been a backdoor attempt to invalidate the NFA. After the House passed the budget bill, GOA immediately announced that they were filing a lawsuit — dubbed the “One Big Beautiful Lawsuit” — along with the Silencer Shop, SilencerCo, Palmetto State Armory, and others to remove silencers and short-barreled firearms from the NFA, arguing that “once the tax is reduced to $0, the constitutional justification for the law collapses.” The NRA, ASA, Firearms Policy Coalition, and Second Amendment Foundation announced that they would file their own lawsuit challenging the constitutionality of the NFA. In a joint statement, the groups applauded Trump’s budget bill, which “serve[s] as a critical step towards our ultimate goal of dismantling the NFA once and for all.”
