The UZI submachine gun is blowback operated weapon which fires from open bolt, smaller variants are considered to be machine pistols, developed in Israel by designer Uziel Gal in around1949, and manufactured by IMI (now IWI Ltd) since about 1951. UZI had been adopted by police and military of more than 90 countries, including Israel (now only in reserve), Germany, Belgium. The Uzi was one of the first weapons to use a telescoping bolt design which allows for the magazine to be housed in the pistol grip for a shorter weapon.

The Uzi uses an open bolt, blowback-operated design quite similar to the Jaroslav Holeček-designed Czech ZK 476 (prototype only) and the production Sa 23, Sa 24, Sa 25, and Sa 26 series of submachineguns, from which it was inspired. The open bolt design exposes the breech end of the barrel, and improves cooling during periods of continuous fire. However, it means that since the bolt is held to the rear when cocked, the receiver is more susceptible to contamination from sand and dirt. It uses a telescoping bolt design, in which the bolt wraps around the breech end of the barrel. This allows the barrel to be moved far back into the receiver and the magazine to be housed in the pistol grip, allowing for a heavier, slower-firing bolt in a shorter, better-balanced weapon.

The receiver is made from stamped steel, with trigger unit and pistol grip pinned to its bottom at the center. The bolt is of "wrap-around" type,with most of its weight located in front of the breech face. The Micro-Uzi has an additional weight, made from tungsten, attached to the bolt, to slightly slowdown the overly excessive rate of fire. The cocking handle is located at the to pof the receiver cover, and does not move when gun is fired; the cocking handle slot is covered by sliding dust cover. Bolt handle is cut at the middle to provide a sighting channel. Gun is fitted with manual safety /fire selector, located on the left side of the grip, plus automatic grip safety at the rear. Full-size Uzi submachine guns were fitted either with a detachable wooden shoulder stock, or with under folding metallic shoulder stock of indigenous design.

The Uzi Carbine is similar in appearance to the Uzi submachine gun for civilian, the Uzi carbine is fitted with a 16-inch (410 mm) barrel (400mm), to meet the minimum rifle barrel length requirement for civilian sales in the United States. It fires from a closed-bolt position in semi-automatic mode only and uses a floating firing pin as opposed to a fixed firing pin. A small number of Uzi Carbines were produced with the standard length barrel for special markets. Uzi Carbines were available in calibers 9mm, .41 AE, and .45 ACP.

The Uzi Carbine had two main variants, the Model A (imported from 1980 to 1983) and the Model B (imported from 1983 until 1989). These two variants were imported and distributed by Action arms.
