The stock is tubular and sidefolding, departing from the complicated retractable design of the Israeli UZI; it pivots underneath the back side of the receiver and lies flat against the right side of the gun when folded. It is longer than the UZI stock (200 millimetres vs. 180), and results more comfortable to operate and to shoulder. The buttpad folds horizontally against the stock when not in use. While the original UZI collapsing stock could be useful as a blunt object/weapon in the event of extremely close engagements or hand-to-hand combat , the SOCIMI Type 821-SMG stock was not designed with such use in mind.
