Judges on the U.S. Court of Appeals for the Fourth Circuit on Wednesday questioned the Second Amendment test to apply in a challenge to Maryland’s ban on assault-style weapons, with some concerned about the real-world implications of the standard pushed by gun rights groups challenging the state law.

The gun rights organizations argue that the Fourth Circuit’s 2017 decision upholding the constitutionality of the Firearm Safety Act should be overturned following the U.S. Supreme Court’s landmark 2022 decision in New York State Rifle & Pistol Association v. Bruen.
