Manufactured using a South African-made Vector Arms UZI as the base, the HR 4332 was part of the final generation of fully transferable American machine guns, manufactured shortly before the Firearm Owners Protection Act (aka House Resolution 4332) went into effect making it among the last fully transferable machine guns manufactured in the United States. The receiver is devoid of the barrel ring and bolt block that would normally prevent installation of military configuration components, and the item is currently fitted with a military-contour SMG barrel, a smooth-sided bolt , an unmarked receiver cover with ratcheting cocking handle, and a full auto trigger group with "A R S" markings. The grips are ribbed, and it has steel folding stock. Includes a shipping box, six extra magazines and a sling.

Excellent, with 98% of the matte gray phosphate finish, showing mild handling marks. The forearm and grip panels are very good, with a few light scuffs and scratches. Mechanically excellent. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 478.
