The American firm Group Industries made limited numbers of a copy of the Uzi "B" model semiauto carbine for sale in the US along with copies of the Uzi submachine gun for the U.S. collectors' market. After registering several hundred submachine guns transferable to the general public through a special government regulated process, production was halted due to financial troubles at the company. Company assets (including partially made Uzi submachine guns, parts, and tooling) were purchased by an investment group later to become known as Vector Arms. Vector Arms built and marketed numerous versions of the Uzi carbine and the Mini Uzi.
