Built on Group Industries’ classic stamped and welded steel receiver with ribbed reinforcement grooves, this HR4332 retains the full-size UZI profile and a matte gray finish. The side-folding stamped-metal stock locks securely, while the black polymer grip frame features ribbed grip panels for a familiar SMG feel. The top cover is Vector Arms-marked, and the rear sight is the UZI top-cover style base with iron sights.
This registered-receiver example is rollmarked "9MM/45ACP/22" and includes both a .45 ACP bolt and barrel and a .22 LR bolt, barrel, and recoil assembly, enabling true multi-caliber use. It accepts standard UZI-pattern magazines, and the package includes a 90-round drum along with multiple box magazines.
The 10.25 inch quick-change barrel system supports rapid swaps, and the select-fire, open-bolt blowback action is managed via standard UZI-pattern safety and fire controls. As a pre-1986 registered-receiver machine gun manufactured in 1986, it carries transferable status under the NFA where lawful.
Receiver markings include the Group Industries Louisville, KY legend with circular logo on the right side. The finish presents uniformly in matte gray across the receiver and stock, aligning with the 1980s U.S.-made production details. This configuration also includes a detachable CSS Model 2000 suppressor as a separate NFA item.
