The Supreme Court seems likely to uphold a major gun regulation imposed by the Biden administration that requires background checks, serial numbers and sales records for the nearly untraceable firearms known as ghost guns.

A majority of the justices seemed skeptical during oral argument on Tuesday of the position taken by gun owners, parts makers and Second Amendment groups: that the government exceeded its authority in 2022 when it imposed new rules for the weapons.

Ghost guns, which have been used in a growing number of crimes over the past decade, are typically assembled at home using parts, kits or pieces printed by 3D printers. Manufacturers say they don’t have to comply with regulations on other guns sold commercially because ghost guns don’t meet the legal definition of a firearm under the nation’s main gun control law and are marketed for hobbyists.
