"Gun Rights Advocates Challenge Colorado's Ghost Gun Ban in Federal Court"

Gun rights organizations, including the Rocky Mountain Gun Owners and the National Association for Gun Rights, have filed a lawsuit against Colorado's ban on ghost guns—untraceable firearms assembled from parts or made using 3D printers. The ban, which took effect on January 1, 2023, is being challenged on the grounds that it violates Second Amendment rights. The lawsuit follows a significant increase in the use of ghost guns in crimes and is part of a broader series of legal challenges against recent gun control measures in Colorado. Governor Jared Polis, named as the defendant, has not commented due to the ongoing litigation.
