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 fitted with a SMG-profile barrel, a smooth-sided bolt numbered "790111/G", receiver cover with ratcheting cocking handle, ribbed forearm and grip panels, "A R S" selector group markings, green nylon sling, and an underfolding buttstock. Include with the lot is a black nylon soft case, four extra magazines, magazine loading tool, and sight adjustment tool.

Excellent, 95% original matte gray finish, showing some light scratches and handling marks concentrated on the receiver and mild wear on the barrel. The furniture is also excellent, with minor dings. 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.
