Manufactured using a South African-made UZI receiver 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 barrel, a smooth-sided bolt, an unmarked receiver cover with ratcheting cocking handle, and a selective fire trigger group with "A R S" position markings. Consecutively serial numbered to the previous lot.

Excellent, retaining 97% plus matte gray finish with light cycling wear and some light handling marks. The forearm and grip panels are very fine, 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 479.
