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 ported barrel, a smooth-sided bolt, receiver cover with ratcheting cocking handle, FAB Defense UTR-M Picatinny handguard, side-folding metal stock, and a selective fire trigger group with "A R S" position markings. Note that while the receiver is marked "9mm/45 ACP/22," the Form 4 paperwork currently lists the gun as 9 mm. Includes a quick-detach vertical fore-grip, Surefire XC1 weapon light, and Blue Force Gear padded sling.

Excellent, retaining 95% matte grey finish and light handling marks. 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.
