A coalition of 15 states and the District of Columbia have filed lawsuits against the Trump administration in a concerted effort to block the distribution of machine-gun conversion devices, commonly referred to as rapid-fire triggers. This legal action follows recent plans to return seized devices that effectively modify semiautomatic firearms into fully automatic weapons. Attorneys General from various states, including Maryland, Illinois, and Washington, have voiced their concerns about the potential dangers posed by such devices. The lawsuits aim to uphold existing regulations and prevent the reintroduction of these controversial technologies, asserting that they remain illegal under many state laws.
