Manufactured by Group Industries prior to the 1986 cutoff on machine gun registration, this UZI bolt is a registered transferable machine gun in its own right, with address and serial number markings on the left side. The right side of the bolt and recoil spring guide are slotted to pass around a semi-automatic restrictor block, allowing a semi-auto UZI to act as a host without heavy modification.

Very fine, with 85% plus matte gray phosphate finish, showing some light cycling wear. 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.

Manufactured in China and imported by A.C.C./Intrac, this Model 320 carbine acts as a host for the Group Industries bolt. Adjustable post front and two-leaf peep rear sights, with the partially ground seven-pointed star on the left side and the manufacturer and import marks on the right. A ratcheting top cover and a full auto grip assembly (with plain English "A F S" selector marks added above the original Israeli marks) are installed, with a semi-auto style bolt block and barrel restrictor ring present, and no bayonet lug. With a set of green painted forearm and grips, and a folding buttstock marked "280" in silver paint. Included with the lot are two extra magazines, sling, cleaning tools, an extra barrel (10 1/4", shortened from a carbine-length barrel and shaped for the restrictor ring), and a generic case.

Fine, with 95% plus refinished matte gray phosphate, showing light handling marks overall. Evidence of welding is present on the frame around the bolt restrictor block, suggesting a past repair. The forearm and grips are very good, with mild scuffing and paint loss. Mechanically excellent.
