Carbines without a stock and not originally manufactured as a rifle are not classified as rifles or short barreled rifles. A carbine manufactured under in length without a forward vertical grip will be a pistol and, state law notwithstanding, can be carried concealed without creating an unregistered Any Other Weapon. A nearly identical carbine with an overall length of or greater is simply an unclassified firearm under Title I of the Gun Control Act of 1968, as the Any Other Weapon catch-all only applies to firearms under or that have been concealed. However, a modification intending to fire from the shoulder and bypass the regulation of short-barreled rifles is considered the unlawful possession and manufacture of an unregistered short-barreled rifle.
