The Uzi (Hebrew: ???? ?, Officially closed as UZI ) Ã, ( Ã, listen ) is a family of open-bolt Israel, blowback- operated submachine weapon. Smaller variants are often regarded as machine guns. Uzi is one of the first weapons to use a telescoping bolt design that allows magazines to be placed in the handle of the gun for shorter weapons.
The first Uzi light machine gun was designed by Major Uziel Gal in the late 1940s. The prototype was completed in 1950. First introduced to the IDF special forces in 1954, the weapon was placed into a common problem two years later. Uzi has found use as a personal defense weapon by rear echelon forces, officers, artillery and tankers, as well as front-line weapons by militant infantry attacks.
Uzi has been exported to more than 90 countries. During his tenure, has been produced by Israel Military Industries, FN Herstal, and other manufacturers. From the 1960s through the 1980s, more Uzi submachine rifles were sold to more military, law enforcement and security markets than any other light machine gun ever made.

Design
The Uzi uses open-bolt, blowback-operated design, very similar to Jaroslav Hole? Ek-designed Czech ZK 476 (prototype only) and production Sa 23, Sa 24, Sa 25, and Sa 26 series submachine gun. The open bolt design exposes the breech end of the barrel, and improves cooling during periods of continuous fire. However, that means that because the bolts are held back when held, the receiver is more susceptible to contamination from sand and dirt. It uses a telescoping bolt design, in which the bolt is wrapped around the end of the barrel's breech. This allows the barrel to be transported far back to the receiver and the magazine to be placed in the pistol grip, allowing for heavier, slower firing bolts in shorter, more balanced weapons.
This weapon is built primarily from patterned metal sheets, making it cheaper per unit to be manufactured than equivalent design machines from wrought. With relatively few moving parts, the Uzi is easily removed for maintenance or repair. The magazine is within the grip of the gun, allowing it to reload intuitively and easily in dark or difficult conditions, under the principle of "hand find hand". The pistol grip is equipped with security grip, making it difficult to shoot accidentally. However, the prominent vertical magazine makes his gun awkward to shoot when prone. Uzi has a bayonet lug.
Operation
The non-reciprocating charging handle on the top of the receiver cover is used to retract the bolt. The variant has a ratchet security mechanism that will capture the bolt and lock it in motion if it is pulled through the magazine, but not far enough to involve the ledge. When the handle is fully pulled back, the bolt will trace (catch) on the sear mechanism and the handle and cover are released to the spring completely forward under the spring strength. The cover will remain during activation because it does not respond to bolts. Military and police versions will go live when installing the cartridge because Uzi is an open bolt gun.
There are two external security mechanisms on the Uzi. The first is a three-position selector lever located at the top of the grip and behind the trigger group. The back position is "S", or "safe" (S = Sicher or Safe in MP2), which locks the lombong and prevents bolt movement.
The second external security mechanism is the security grip, which is located at the back of the handle. This is intended to help prevent unintentional release if the weapon is dropped or the user loses a strong grip on the weapon during the shoot.
The trigger mechanism is a conventional fire trigger, but works only to control the release mechanism for either a bolt (light machine gun) or a firing pin mechanism (semi-automatic) because Uzi does not incorporate internal cocking or hammer mechanisms. While the open-bolt system is mechanically simpler than the closed-bolt design (eg Heckler & Koch MP5), it creates a noticeable delay between when the trigger is pulled and when the gun fires.
The magazine release button or lever is located at the bottom of the gun handle and is meant to be manipulated by a non-firing hand. Row-like buttons lie flat with a pistol grip to help prevent accidental releases from magazines during rigorous or careless handling.
When the gun is removed, the ejector port is closed, preventing the entry of dust and dirt. Although the Uzi metal-finish receivers are equipped with pressed reinforcing slots to receive dirt and sand accumulation, they can still jam with heavy sand accumulations in desert combat conditions when they are not cleaned regularly. The magazine should be removed before extinguishing the weapon.
There are different stocks available for the right Uzi. There is a wooden broth with metal buttplate that comes in three similar variations used by IDF. The first version has a flat butt and a straight comb and has holes for cleaning rods and gun oil bottles. The second has a tilted butt and a straight comb and no basin. The third has an oblique butt and a curved comb and no basin; polymer version currently available from IMI. Wood stocks initially have a fast release base but are sold in the United States have a permanent basis to comply with US weapons laws.
Choate makes an aftermarket polymer stock with a rubber buttpad that has a flat bottom, straight comb, and a permanent base.
In 1956, IMI developed twin-strut metal stocks folding down with two rotating sections that folded under the back of the receiver. Mini Uzi has a stock of single front-strut single-strut metal an inch longer than Uzi. The buttplate can be used as a foregrip when stored. Micro Uzi has a similar model.
Magazines
The original box magazine for 9mm Uzi has a capacity of 25 rounds. Experimental magazines of 40 and 50 rounds were tried but found to be unreliable. A 32-round extended magazine was then tried and then accepted as a standard. Mini Uzi and Micro Uzi use shorter 20 lap magazines. Additional magazines available include 40-, and 50-round magazines. Other high-capacity aftermarket magazines exist such as the 70-round Vector Arms and 100-round drum Beta Company (Beta C-Mag).
The.45 ACP Uzi uses 16 or 22 lap magazines, while.45 ACP Micro Uzi and Mini Uzi use 12-round magazines. The Vector Arms conversion tool allows.45-caliber caliber to use the same 30-round magazine as the M3 "Grease Gun".
Conversion of caliber
Uzi is available with caliber conversion kits in 0.22 LR or 0.41 AE. Operators only need to replace barrel, bolt and magazine. The22 LR has 20-round magazines; The original IMI kit uses a barrel insert while the Action Arms aftermarket kit uses a full surrogate barrel. The41 AE also has a 20-round magazine; because it has the same bolt as Parabellum 9ÃÆ' â € "19mm, only barrels and magazines that need to be changed.
IMI also produces a.45ACP conversion kit in full auto/open bolt with 10.2 "barrel for 9mm SMG and only semi/closed bolt with 16" barrel for carbine version. Limited magazine capacity, with 2 sizes of 16 and 10 rds each.
Convert the aftermarket caliber also in.40 S & amp; W and 10mm Auto. Because these calibers have the same bolts as the parabellum 9ÃÆ'â € "19mm Parabellum, the bolts need not be changed. The 0.40 S & amp; W kit can be used with normal 9mm Uzi but 10 mm Auto kit is required to use 0.45 ACP Uzi due to its larger size and power.

Operational usage
The Uzi light machine gun was designed by Captain (then Major) Uziel Gal of the Israeli Defense Force (IDF) after the 1948 Arab-Israeli War. The weapon was handed over to the Israeli Army for evaluation and win over a more conventional design due to its simplicity and its manufacture economy. Gal did not want the weapon to be named after him, but his request was ignored. The Uzi was formally adopted in 1951. First introduced to the IDF special forces in 1954, the weapon was placed into a common problem two years later. The first Uz tribe was equipped with short but fixed wooden buttstocks, and this was the version that initially saw the battle during the Suez Campaign of 1956. Later the model would be equipped with a folding metal stock.
Uzi is used as a personal defense weapon by rear echelon forces, officers, artillery and tankers, as well as front-line weapons by elite light infantry assault troops. The compact size and Uzi weapons proved to be instrumental in clearing the Syrian bunker and Jordanian defense positions during the 1967 Six Day War. Although the weapon had been removed from the front line of the IDF service in the 1980s, some Uzis and Uzi variants were still used by IDF units until December 2003, when the IDF announced that it had withdrawn Uzi from all IDF forces. It was later replaced by fully automatic Auto Tavor.
In general, Uzi is a reliable weapon in military service. However, even Uzi became the victim of extreme conditions of sand and dust. During the Sinai Campaign of the Yom Kippur War, IDF army units reaching the Suez Canal reported that of all their small arms, only FN MAG 7.62 mm machine guns were still operating.
The Uzi proved to be very useful for mechanical infantry in need of compact weapons, and for infantry units cleaning up bunkers and other confined spaces. However, limited range and accuracy in automatic fire (about 50 m) can be confusing when facing enemy forces armed with small long-range weapons, and heavier support weapons can not always replace longer individual guns. This failure eventually led to a gradual cessation of the Uzi from the IDF front-line attack unit.
Uzi has been used in conflicts outside of Israel and the Middle East during the 1960s and 1970s. The number of 9 mm Uzi light machine guns was used by Portuguese cavalry, police, and security forces during the Portuguese Colonial War in Africa.
Worldwide sales
Total arms sales to date (late 2001) have captured more than $ 2 billion (US) IMI, with more than 90 countries using either weapons for their armed forces or in law enforcement.
- The Royal Dutch Army first issued the Uzi in 1956. This was the first country other than Israel to use it as a service weapon. Their models are different because they have wood stocks made to their more angled specifications, have tilted buttocks and curved combs, and are 2 inches longer than the IDF model.
- The German Bundeswehr (especially its tank crew) uses Uzi since 1959 under MP2 designation. It replaces MP1 (Beretta M1938/49) and Thompson M1 in service. MP2 is equipped with IDF-style wooden stock and MP2A1 then equipped with metal folding stock. This can be identified by the three-position "DES" selector switch: "D" for " Dauerfeuer " ("continuous-fire", or "automatic"), "E" for " Einzelfeuer "(" single-fire ", and" S "for" Sicher "(" safe "or" safe "). The Bundeswehr is lowered to use backup after adopting Heckler & amp; Koch MP5 in 1985. Replaced with Heckler & amp; Koch MP7 Personal Defense Weapon in 2007.
- The Belgian Armed Forces have used Uzi machine guns in 9mm,.45 ACP and 22LR caliber, licensed by FN Herstal from 1958 to 1971. They were also issued to paramilitary Gendarmerie.
- The Irish GardaÃÆ' ERU and RSU issued Uzi from the 1970s to 2012. It was replaced by Heckler & amp; Koch MP7 in March 2014.
- In Rhodesia, Uzi was produced under license from 1976 until the fall of Rhodesia in 1980. It was made of components supplied by Israel (and later made by Rhodesia).
- Sri Lanka ordered several thousand Mini Uzi and Uzi carbines in the 1990s. Currently they are deployed with the Sri Lankan Army, the Sri Lankan Armed Forces, and the Sri Lankan Police Special Forces as their primary weapons while providing security for VIPs.
- The US Secret Service used Uzi as their standard light machine gun from the 1960s to the early 1990s, when it was removed and replaced with Heckler & amp; Koch MP5 and FN P90. When President Ronald Reagan was shot on March 30, 1981, Special Agent of the Secret Service Robert Wanko pulled Uzi out of the suitcase and covered the back of the presidential limousine as he drove to safety with the wounded president inside.
- All cruise merchants from the Zim Integrated Shipping line are trained in use, and issued, Uzi.
Military variant
Uzi Submachine Gun is a standard Uzi with a 10 inch (250 mm) barrel. It has an automatic fire rate of 600 revolutions per minute (rpm) when the chamber in Parabellum is 9mm; the fire rate of the.45 ACP model is slower at 500 rpm.
The Mini Uzi is a smaller version of the regular Uzi, first introduced in 1980. Mini Uzi is a length of 600Ã, mm (23.62Ã, inches) or 360Ã, mm (14.17 inches) long with stocks folded. The length of the barrel is 197 mm (7.76 inches), the barrel velocity is 375 m/s (1230 f/s) and its effective range is 100 m. It has an automatic rate greater than 950 revolutions per minute due to shorter bolts. Its weight is about 2.7 kg (6.0 lb).
The Micro Uzi is a lower version of Uzi, introduced in 1986. Micro Uzi is 486 mm (19.13 inches) in length, reduced to 282 mm (11.10 inches) with stock folded and long the barrel is 117 mm. Its muzzle velocity is 350 m/s (1148 f/s) and its cycle rate is 1,200 rpm. It weighs a little over 1.5 kg (3.3 pounds).
The Uzi Pro , an enhanced variant of Micro Uzi, was launched in 2010 by Israel Weapon Industries Ltd. (IWI), formerly of the "small arms" division of the Israeli Military Industry. The Uzi Pro is a blowback-operated, fire-select, bolt-covered submachine gun with a larger bottom, comprising a handle and a handguard, made entirely of polymers to reduce weight; The grip section is redesigned to allow two-handed operation and facilitates control in full automatic fire with small firearms. Uzi Pro has three Picatinny rails, two on the sides of the barrel and one at the top for optics, a tilt handle that has been moved on the left side. This new weapon weighs 2.32 kg and has a length of 529 mm with extended stock, and 30 cm while collapsed. It has been purchased by IDF in limited quantities for evaluation and has not yet decided whether or not to order additional units for all special forces.
Civilian variant
Uzi carbine
Uzi's carbide is similar in appearance to the Uzi light machine gun. The Uzi carbine is equipped with 16-inch (410 mm) barrels (400mm), to meet minimum length barrel gun requirements for civilian sales in the United States. Small amounts of Uzi carbine are produced with standard long barrel for special markets. It lights up from a closed-bolt position in semi-automatic mode only and uses floating shooting as a fixed firing pin repellent. FS style selector switch has two positions (automatic setting blocked): "F" for "fire" (semi-automatic) and "S" for "safe". Uzi carbines are available in.22LR, 9mm,.41 AE, and.45 ACP caliber.
Uzi carbine has two main variants, Model A (imported from 1980 to 1983) and Model B (imported from 1983 to 1989). Both variants are imported and distributed by Action Arms.
The American company Group Industries made a limited number of copies of the Uzi "B" semiauto carbine model for sale in the US along with a copy of the Uzi light machine gun for the US collector market. After registering several hundred submachine weapons that can be transferred to the general public through a process governed by a special government, production stalled due to financial problems at the company. Company assets (including light machine guns, components, and parts equipment) Uzi made partially purchased by an investment group later known as Vector Weapon. Vector Arms builds and markets many versions of Uzi carbine and Mini Uzi.
Currently, while the civilian manufacture, sale and ownership of post-1986 select-fire Uzi and its variance is prohibited in the United States it is still legal to sell templates, tools and manuals to complete the conversion. These items are usually marketed as "post-sample" materials for use by Federal Firearm Licensees to make/distribute fire-select variants from Uzi to Law Enforcement, Military and Overseas customers.
Mini Uzi carbine
The Mini Uzi Carbine is similar in appearance to the Uzi Mini machine gun. Uzi Mini Carbide is equipped with a 19.8 inch barrel, to meet the minimum length requirement of minimum rifle for civilian sales in the United States. It fires from a closed-bolt position in semi-automatic mode only.
Uzi Pistol
The Uzi Pistol is a semi-automatic, closed bolt, and a pistol-operated blowgun variant. Its muzzle speed is 345 m/s. This is Micro Uzi with no shoulder stock or full automatic shooting ability. Users of the gun in question are various security agencies that require high-capacity semi-automatic pistols, or civilian shooters who want weapons of quality and familiarity with the Uzi style. It was introduced in 1984 and produced until 1993.
Foreign copy
AG Strojnica ERO
The Strojnica ERO (Group Gun "ERO machine gun") is a Uzi Croatian clone that was made locally by Arma Grupa of Zagreb during the Yugoslav War. It is the same dimension as the Uzi unless it is entirely made of stamped steel, causing it to be heavier (3.73 kg/8.22 lbs). The only difference from UZI is that the selector switch is marked R ( Rafalno & gt; "Burst", or "Full Auto"), P ( Pojedina? no & gt; "Single Fire") and Z ( Zaklju? an & gt; "Locked", or "Safe" ) and the Rate of Fire is 650 revolutions per minute. It uses 32-round magazines as standard, but can use any 9mm Uzi-interface magazine from 25-lap or larger.
The Strojnica Mini ERO is a copy of Micro Uzi; it's different because it has large folding wire stocks like Vz.61 Skorpion Machine Pistol. It weighs 2.2 kg/4.85 lbs. disassembled and 545.5 mm/21.47 inches overall with extended folding stock and 250 mm/9.84 inches with stocks folded. It uses Uzi Mini magazine 20 rounds.
Socimi Type 821
At first glance Socimi Type 821-SMG appears to be an official copy of Israel from Uzi Israel, although its design has many differences and improvements over the original project. The SOCIMI company has been active in the railway development sector since the early 1970s; in 1983, he entered in a Joint Venture with the manufacturer of the firearms Luigi Franchi S.p.A. (which later, specifically in 1987, would take over) to concentrate on the military arms business. The results of this collaboration are a series of assault rifles, and Type 821-SMG. The initial prototypes and sub-machinegun evaluation samples were immediately produced by Franchi, until SOCIMI completed equipment to start in-house production.
Norinco M320
Norinco of China made unauthorized copies of Model B Uzi sold as M320. The initial version is marked "Model POLICE" in English. Modifications are made to avoid US Assault Weapons Import Ban: folding stock replaced with wooden thumb stock, welded barrel nip in place, and lontong bayonet is released. The gun has a gray finish, a 410 mm (16 inch) long carbine barrel and an overall width of 800 mm (31.49 inches).
