Measuring 5 3/4 inches long (sans recoil spring unit), this conversion bolt is designed for use in full-sized closed-bolt Uzis with a bolt restrictor block. The SWD address and serial number are engraved on top, with the semi-automatic firing pin discarded and replaced with a welded-on support rail on the left side and a fixed firing pin. With plastic UZI case and two extra magazines.

Manufactured in Israel and imported by Action Arms of Philadelphia, Pennsylvania, the UZI Model B currently hosts the automatic conversion bolt described in item "A" of this lot. An Israeli-marked three position full/semi/safe trigger group has been installed and a carbine-profile barrel cut down to SMG length, but the non-ratcheting top cover is still installed and no permanent modifications have been made to the receiver. Features adjustable post front and peep rear sights, bayonet lug, folding stock, and ribbed pistol grip.
