AK-47

The AK-47 is a selective-fire, gas-operated 7.62×39mm assault rifle, first developed in the USSR by Mikhail Kalashnikov. It is officially known as Avtomat Kalashnikova (Russian: Автомат Калашникова). It is also known as a Kalashnikov, an AK or in Russian slang, Kalash.
Design work on the AK-47 began in the last year of World War II (1945). After the war in 1946, the AK-46 was presented for official military trials. In 1947 the fixed-stock version was introduced into active service with selected units of the Soviet Army. An early development of the design was the AKS (S—Skladnoy or "folding"), which was equipped with an underfolding metal shoulder stock. In 1949, the AK-47 was officially accepted by the Soviet Armed Forces and used by the majority of the member states of the Warsaw Pact.
The original AK-47 was one of the first true "assault rifles" to be manufactured, after the original Sturmgewehr 44.Even after six decades the model and its variants remain the most widely used and popular assault rifles in the world because of their durability, low production cost, and ease of use. It has been manufactured in many countries and has seen service with armed forces as well as irregular forces worldwide. The AK-47 was the basis for developing many other types of individual and crew-served firearms. More AK-type rifles have been produced than all other assault rifles combined

Design

The first assault rifle to see service was created in 1915 by Vladimir Fyodorov, following the experience gathered in the Russo-Japanese War. Several countries had already developed and adopted low-power rifle cartridges since 1890s (such as 6.5×52mm Mannlicher-Carcano) as their standard infantry ammunition. The Russo-Japanese war, however, had demonstrated the regular rifles' lack of suppressive firepower, in addition to the excessive range of their ammunition. The latter was also confirmed in World War I. The Fyodorov's assault rifle went out of production after the Soviet armed forces decided to standardize its infantry weaponry around only the most popular types of cartridges following the Russian Civil War. The Soviet Union had returned to the development of an assault rifle in 1942 when the need for an intermediate-powered rifle became clearly evident.By that time submachine guns were already in widespread use but they could not replace service rifles because of limited power of pistol cartridges. Like the Germans, the Soviets designed an intermediate cartridge that could be made on existing production lines (despite Vladimir Fyodorov's insistence on a special small-calibre cartridge) he work on the weapons for the new ammunition commenced in 1943, with the AK-47 of Mikhail Kalashnikov, the SKS-45 of Sergei Simonov and the RPD of Vasily Degtyaryov emerging as the victors.
Mikhail Kalashnikov began his career as a weapon designer while in a hospital after he was shot in the shoulder during the Battle of Bryansk. After tinkering with a submachine gun design, he entered a competition for a new weapon that would chamber the 7.62×41mm cartridge developed by Yelizarov and Syomin in 1943 (the 7.62×41mm cartridge predated the current 7.62×39mm M1943). A particular requirement of the competition was the reliability of the firearm in the muddy, wet, and frozen conditions of the Soviet front line. Kalashnikov designed a carbine, strongly influenced by the American M1 Garand, that lost out to the Simonov design (scaled down PTRS-41), that later became the SKS semi-automatic carbine. At the same time, the Soviet Army was interested in developing a true assault rifle employing a shortened M1943 round. The first such weapon was presented by Sudayev in 1944, but trials found it to be too heavy. A new design competition was held two years later where Kalashnikov and his design team submitted an entry. It was a gas-operated rifle which had a breech-block mechanism similar to his 1944 carbine, and a curved 30-round magazine.

Kalashnikov's rifles (codenamed AK-1 and −2) proved to be reliable and the weapon was accepted to second round of competition along with designs by A. A. Dementyev and A. A. Bulkin. In late 1946, as the rifles were being tested, one of Kalashnikov's assistants, Aleksandr Zaitsev, suggested a major redesign of AK-1, particularly to improve reliability. At first, Kalashnikov was reluctant, given that their rifle had already fared better than its competitors. Eventually, however, Zaitsev managed to persuade Kalashnikov. The new rifle was produced for a second round of firing tests and field trials. There, Kalashnikov assault rifle model 1947 proved to be simple and reliable under a wide range of conditions with convenient handling characteristics. Production began on 6 July 1947, and in 1949 it was adopted by the Soviet Army as "7.62mm Kalashnikov assault rifle (AK)".
The AK-47 is best described as a hybrid of previous rifle technology innovations: the trigger, double locking lugs and unlocking raceway of the M1 Garand/M1 carbine, the safety mechanism of the John Browning designed Remington Model 8 rifle,and the gas system of the Sturmgewehr 44. Kalashnikov's team had access to all of these weapons and had no need to "reinvent the wheel"though he denied that his design was based on the German Sturmgewehr 44 assault rifle.Kalashnikov himself observed: "A lot of Russian Army soldiers ask me how one can become a constructor, and how new weaponry is designed. These are very difficult questions. Each designer seems to have his own paths, his own successes and failures. But one thing is clear: before attempting to create something new, it is vital to have a good appreciation of everything that already exists in this field. I myself have had many experiences confirming this to be so." There are claims about Kalashnikov copying other designs, like Bulkin's TKB-41 or Simonov's AVS-31

Features

The main advantages of the Kalashnikov rifle are its simple design, fairly compact size, and adaptation to mass production. It is inexpensive to manufacture and easy to clean and maintain. Its ruggedness and reliability are legendary. The AK-47 was initially designed for ease of operation and repair by glove-wearing Soviet soldiers in Arctic conditions. The large gas piston, generous clearances between moving parts, and tapered cartridge case design allow the gun to endure large amounts of foreign matter and fouling without failing to cycle. This reliability comes at the cost of accuracy, as the looser tolerances do not allow for precision and consistency[citation needed]. Reflecting Soviet infantry doctrine of its time, the rifle is meant to be part of massed infantry fire, not long range engagements.
Aside from USSR the AK-47 and its variants were/are made in dozens of countries, with “quality ranging from finely engineered weapons to pieces of questionable workmanship.”For example, Arsenal-made AK has a system life of 15,000 rounds
The bore and chamber,as well as the gas piston and the interior of the gas cylinder, are generally chromium-plated. This plating dramatically increases the life of these parts by resisting corrosion and wear. This is particularly important, as most military-production ammunition (and virtually all ammunition produced by the Soviet Union and other Warsaw Pact nations) during the 20th century contained potassium chlorate in the primers. On firing, this was converted to corrosive and hygroscopic potassium chloride which mandated frequent and thorough cleaning in order to prevent damage. Chrome plating of critical parts is now common on many modern military weapons

Ishapore 2A/2A1

The Rifle 7.62mm 2A/2A1 (also known as the Ishapore 2A/2A1) is a 7.62mm NATO (7.62x51) calibre bolt-action rifle adopted as a reserve arm by the Indian military in 1963. The design of the rifle - initially the Rifle 7.62mm 2A - began at the Ishapore Rifle Factory of the Ordnance Factories Board in India, soon after the Sino-Indian War of 1962.
The Ishapore 2A/2A1 has the distinction of being the last bolt-action rifle designed to be used by a regular military force other than specialized sniper rifles. Due to fluctuating supplies of affordable .303 British ammunition, the Ishapore rifles are becoming increasingly popular with civilian shooters and collectors in Australia, United Kingdom and the United States

Design

Externally the Ishapore 2A/2A1 rifle was based upon (and is almost identical to) the .303 British calibre SMLE Mk III* rifle, with the exception of the distinctive “square” (10 or 12 round) magazine. The rifle was designed to allow the British Pattern 1907 (P'07) sword bayonet to be attached. There were other differences to the Ishapore 2A/2A1 rifles that include the use of improved steel (to handle the increased pressures of the 7.62mm NATO round), and a redesigned extractor to cope with the rimless round. Production of these rifles started in early 1960s and is believed to have been discontinued in 1975. The original (2A) design incorporated the Lee-Enfield rear sight which had metric graduations out to 2000 meters. The re-designated "Rifle 7.62mm 2A1" incorporated a more realistic 800 meter rear sight. The stock is recycled from the No. 1 Mk. III armory stock, with the addition of a cross screw forward of the magazine well. Some stocks were salvaged from existing surplus and show artificer repairs where rotted or damaged wood has been replaced, this is especially evident with the recoil draws that often fail over time due to the rifle being rack stored butt down / muzzle up that allows oils and grease to migrate downwards into this critical area
                     
The Ishapore 2A and 2A1 rifles are often incorrectly described as ".308 conversions". In fact, the 2A/2A1 rifles are not conversions of .303 calibre SMLE Mk III* rifles: they were designed and built right from the outset to fire 7.62mm NATO ammunition. Although the 7.62mm NATO and commercial .308 Winchester ammunition are physically interchangeable, these weapons were not designed for use with commercial .308 Winchester ammunition. One of the most noted misconceptions between the 7.62mm NATO and commercial .308 Winchester ammunition; "the .308 Winchester generates significantly higher pressures than 7.62mm NATO ammunition". This is due to incorrectly substituting the SAAMI (piezoelectric transducer) pressure measurement system with the (Copper Units of Pressure, "CUP") measurement system. The original specifications for 7.62mm NATO (M80 BALL) ammunition uses the CUP (Copper Units of Pressure) method. The commercial ammunition usually conforms to the SAAMI standards using the (piezoelectric transducer system) AND/OR the (Copper Units of Pressure, CUP) pressure measurement systems.
For example, 7.62mm NATO ammunition that has been subjected to 125°F to -65°F storage conditions can have an average pressure that shall not exceed 55,000 CUP (Copper Units of Pressure).Whereas commercial .308 Winchester ammunition can have a SAAMI/ANSI maximum average pressure of 62,000 PSI (piezoelectric method) OR a maximum average pressure of 52,000 CUP (copper units of pressure);both of these measurements from SAAMI are one and the same, they just represent different methods of measuring (such as inches and millimeters).
The real issue is the differences in the NATO vs. COMMERCIAL cartridge cases, typically the commercial cases are thinner than the NATO cases. Firing commercial cases in NATO chambers can possibly lead to problems, such as a ruptured case, because NATO chamber head space is longer.[4] Prior to firing ANY .308 Winchester ammunition through a 7.62mm NATO chambered rifle, it is strongly advised to check the headspace using a "field" gauge for commercial .308 Winchester ammunition. Doing so will ensure that it is truly safe to fire commercial ammunition in a NATO chamber. The simplest and safest solution is to use 7.62mm NATO ammunition exclusively.

The Fusil Automatique Léger

The Fusil Automatique Léger ("Light Automatic Rifle") or FAL is a self-loading, selective fire battle rifle produced by the Belgian armaments manufacturer Fabrique Nationale de Herstal (FN). During the Cold War it was adopted by many North Atlantic Treaty Organization (NATO) countries, with the notable exception of the United States. It is one of the most widely used rifles in history, having been used by over 90 countries.[3]
The FAL was predominantly chambered for the 7.62×51mm NATO round, and because of its prevalence and widespread use among the armed forces of many NATO countries during the Cold War it was nicknamed "The right arm of the Free World".
A British Commonwealth derivative of the FN FAL has been produced under licence as the L1A1 Self-Loading Rifle.

History

In 1947, the first FN FAL prototype was completed. It was designed to fire the intermediate 7.92×33mm Kurz cartridge developed and used by the forces of Nazi Germany during World War II (see StG44 assault rifle). After testing this prototype in 1948, the British Army urged FN to build additional prototypes, including one in bullpup configuration, chambered for their new .280 British caliber intermediate cartridge.After evaluating the single bullpup prototype, FN decided to return instead to their original, conventional design for future production.
In 1950, the United Kingdom presented the redesigned FN rifle and the British EM-2, both in .280 British calibre, to the United States for comparison testing against the favoured United States Army design of the time—Earle Harvey's T25.It was hoped that a common cartridge and rifle could be standardized for issue to the armies of all NATO member countries. After this testing was completed, U.S. Army officials suggested that FN should redesign their rifle to fire the U.S. prototype ".30 Light Rifle" cartridge. FN decided to hedge their bets with the U.S., and in 1951 even made a deal that the U.S. could produce FALs royalty-free, given that the UK appeared to be favouring their own EM-2.
This decision appeared to be correct when the British Army decided to adopt the EM-2 and .280 British cartridge in the very same month. This decision was later rescinded after the Labour Party lost the 1951 General Election and Winston Churchill returned as Prime Minister. It is believed that there was a quid pro quo agreement between Churchill and U.S. President Harry Truman in 1952 that the British accept the .30 Light Rifle cartridge as NATO standard in return for U.S. acceptance of the FN FAL as NATO standard. The .30 Light Rifle cartridge was in fact later standardized as the 7.62 mm NATO; however, the U.S. insisted on continued rifle tests. The FAL chambered for the .30 Light Rifle went up against the redesigned T25 (now redesignated as the T47), and an M1 Garand variant, the T44. Eventually, the T44 won out, becoming the M14. However, in the meantime, most other NATO countries were evaluating and selecting the FAL.
FN created what is possibly the classic post-war battle rifle. Formally introduced by its designers Dieudonné Saive and Ernest Vervier in 1951, and produced two years later, it has been described as the "Right Arm of the Free World."[6] The FAL battle rifle has its Warsaw Pact counterpart in the AKM, each being fielded by dozens of countries and produced in many of them. A few, such as Israel and South Africa, manufactured and issued both designs at various times. Unlike the Soviet AKM assault rifle, the FAL utilized a heavier full-power rifle cartridge.


Design

The FAL operates by means of a gas-operated action very similar to that of the Russian SVT-40. The gas system is driven by a short-stroke, spring-loaded piston housed above the barrel, and the locking mechanism is what is known as a tilting breechblock. To lock, it drops down into a solid shoulder of metal in the heavy receiver much like the bolts of the Russian SKS carbine and French MAS-49 series of semi-automatic rifles. The gas system is fitted with a gas regulator behind the front sight base, allowing adjustment of the gas system in response to environmental conditions. The piston system can be bypassed completely, using the gas plug, to allow for the firing of rifle grenades and manual.The FAL's magazine capacity ranges from five to 30 rounds, with most magazines holding 20 rounds. In fixed stock versions of the FAL, the recoil spring is housed in the stock, while in folding-stock versions it is housed in the receiver cover, necessitating a slightly different receiver cover, recoil spring, and bolt carrier, and a modified lower receiver for the stock.
FAL rifles have also been manufactured in both light and heavy-barrel configurations, with the heavy barrel intended for automatic fire as a section or squad light support weapon. Most heavy barrel FALs are equipped with bipods, although some light barrel models were equipped with bipods, such as the Austrian StG58 and the German G1, and a bipod was later made available as an accessory.
Among other 7.62×51mm NATO battle rifles at the time, the FN FAL had relatively light recoil, due to the gas system being able to be tuned via regulator in fore-end of the rifle, which allowed for excess gas which would simply increase recoil to bleed off. In fully automatic mode, however, the shooter receives considerable abuse from recoil, and the weapon climbs off-target quickly, making automatic fire only of marginal effectiveness. Many military forces using the FAL eventually eliminated full-automatic firearms training in the light-barrel FAL.

INSAS

INSAS (an abbreviation of Indian Small Arms System) is a family of infantry arms consisting of an assault rifle, a light machine gun and a carbine. It is manufactured by the Ordnance Factories Board at Ordnance Factory Tiruchirappalli, Small Arms Factory Kanpur and Ishapore Rifle Factory. The Insas Assault Rifle is the standard infantry weapon of the Indian Armed Forces.

History

The Indian armed forces had been equipped with a copy of the Belgian FN FAL rifle since the 1950s. This copy was considered to be a distinct weapon, since its parts cannot be interchanged with either the metric or inch-pattern versions of the FAL.[1] With the 7.62 mm semi-automatic rifle becoming obsolete in the 1980s, India began to develop the INSAS, incorporating features from several contemporary rifle designs. Although largely based on the AKM, the INSAS has a number of differences, making it a unique weapon.
During the late 1980s, the Indians expressed interest in purchasing (and possibly manufacturing under license), an East German-designed AK chambered for the 5.56x45mm cartridge.[2] The deal ultimately fell through.
The INSAS system was originally planned to have three component weapons: a standard rifle, a carbine, and a squad automatic rifle (LMG), all chambered for 5.56x45mm NATO ammunition. In 1997 the rifle and LMG were ready for mass production, and in 1998 the first Indian army units were observed armed with INSAS rifles for the Republic Day Parade. The mass introduction of the INSAS rifle was initially delayed by the lack of domestically made 5.56 mm ammunition; India accordingly bought significant stocks from the Israeli company, IMI.[citation needed] At least 300,000 INSAS rifles are in service with the Indian army; some of these have seen action in Indo-Pakistani conflicts.

Design

The INSAS rifle is based on the Kalashnikov AK-47 action with modifications. The basic gas-operated action (long stroke gas system, rotating bolt, and stamped steel receiver) is of the Kalashnikov pattern. The gas system is fitted with a manual gas regulator similar in design to that found on the FN FAL as well as a gas cutoff. The charging handle is positioned on the left side of the forearm; it is similar in position and design to the German HK G3 rifle.
The selector/safety switch is located on the left side of the receiver above the pistol grip, which allows single shots and three-round bursts. The rifle is fitted with a side-folding carrying handle, and either a solid or side-folding metal buttstock. Furniture is made of polymer with the stock using the butt-plate from Lee-Enfield rifles. Standard magazines are made from semi-translucent polymer and contain 20 rounds. Longer 30-round magazines of similar design are available for the INSAS LMG but can also be used in the rifle. The sights consist of a hooded front, mounted on top of the gas block, and a diopter rear, mounted on the receiver cover. The flash suppressor is shaped to accept NATO-standard rifle grenades. It can be fitted with an AKM-style multipurpose knife-bayonet.
The assault rifle version has semi-auto and 3-round burst modes much like the US M16A2. Derived from the INSAS weapon systems, the INSAS Excalibur Mark-I is ergonomically designed with a folding butt and can be fitted with 20 and 30-round magazines. It is also fitted with a Picatinny rail for mounting of opto-electronic devices. The latest variant of the INSAS has semi-automatic, 3 round bursts and full automatic fire modes.
An under-barrel grenade launcher and bayonet have been recently been issued for use with the INSAS, which are also compatible with the AK-47s used by paramilitary forces.

Variant

INSAS Standard rifle (5.56 mm) issued to Indian Army & Paramilitary, with folding and fixed butt variants, fires semi-automatic and three round burst. An assault variant is also manufactured with full auto fire mode along with semi & three burst mode, used by Indian Army.
INSAS (Foldable Butt) (5.56 mm) It resembles 5.56 mm Assault Rifle Fixed Butt in all other features except that the Fixed Butt is replaced with a foldable type of Butt to shorten the overall length and it does not include automatic mode of firing.It is most suitable for combat from ICV and in Para Troopers role.[5]
INSAS LMG 5.56 mm INSAS (folding and fixed butt variants) - An Indian version of Squad Automatic Weapon (SAW) Incorporated for suppressive and cover fire for troops. Barrel is designed for long and continued fire,It has auto fire mode with 30 round feed capacity along with Bipods. Meant to replace the old Bren LMG.

Heckler & Koch MP5

The Heckler & Koch MP5 (from German: Maschinenpistole 5, "machine pistol model 5") is a 9mm submachine gun of German design, developed in the 1960s by a team of engineers from the German small arms manufacturer Heckler & Koch GmbH (H&K) of Oberndorf am Neckar. There are over 100 variants,[4] including a semi-automatic version.
The MP5 is one of the most widely used submachine guns in the world, having been adopted by 40 nations and numerous military, law enforcement, intelligence, and security organizations.In the 1990s, Heckler & Koch developed the Heckler & Koch UMP, the MP5's successor; both are available as of 2012.

History

Heckler & Koch, encouraged by the success of the G3 automatic rifle, developed a family of small arms consisting of four types of firearms all based on a common G3 design layout and operating principle. The first type was chambered for 7.62×51mm NATO, the second for the 7.62×39mm M43 round, the third for the intermediate 5.56×45mm NATO caliber, and the fourth type for the 9×19mm Parabellum pistol cartridge. The MP5 was created within the fourth group of firearms and was initially known as the HK54.
Work on the MP5 began in 1964 and two years later it was adopted by the German Federal Police, border guard and army special forces.
The MP5 is manufactured under license in several nations including Greece (formerly at EBO – Hellenic Arms Industry, currently at EAS – Hellenic Defense Systems), Iran (Defense Industries Organization), Mexico (SEDENA), Pakistan (Pakistan Ordnance Factories), Saudi Arabia, Sudan (Military Industry Corporation), Turkey (MKEK), and the United Kingdom (initially at Royal Ordnance, later diverted to Heckler & Koch Great Britain).

Features

The first MP5 models used a double-column straight box magazine, but since 1977, slightly curved, steel magazines are used with a 15-round capacity (weighing 0.12 kg) or a 30-round capacity (0.17 kg empty).The adjustable iron sights (closed type) consist of a rotating rear diopter drum and a front post installed in a hooded ring. The rear sight is adjustable for both windage and elevation with the use of a special tool, being adjusted at the factory for firing at 25m with standard 124 grains FMJ 9x19mm NATO ammunition; the drum provides four different apertures of varying width used to adjust the light entrance in the diopter system, according to the user's eye relief and tactical situation, and not for firing at 25, 50, 75 and 100m as some people wrongly imagine.
The MP5 has a hammer firing mechanism. The trigger group is housed inside an interchangeable polymer trigger module (with an integrated pistol grip) and equipped with a three-position fire mode selector that serves as the manual safety toggle. The “S” or Sicher position in white denotes weapon safe, “E” or Einzelfeuer in red represents single fire, and “F” or Feuerstoß (also marked in red) designates continuous fire. The SEF symbols appear on both sides of the plastic trigger group. The selector lever is actuated with the thumb of the shooting hand and is located only on the left side of the original SEF trigger group or on both sides of the ambidextrous trigger groups. The safety/selector is rotated into the various firing settings or safety position by depressing the tail end of the lever. Tactile clicks (stops) are present at each position to provide a positive stop and prevent inadvertent rotation. The "safe" setting disables the trigger by blocking the hammer release with a solid section of the safety axle located inside the trigger housing.
The non-reciprocating cocking handle is located above the handguard and protrudes from the cocking handle tube at approximately a 45° angle. This rigid control is attached to a tubular piece within the cocking lever housing called the cocking lever support, which in turn, makes contact with the forward extension of the bolt group. It is not however connected to the bolt carrier and therefore cannot be used as a forward assist to fully seat the bolt group. The cocking handle is held in a forward position by a spring detent located in the front end of the cocking lever support which engages in the cocking lever housing. The lever is locked back by pulling it fully to the rear and rotating it slightly clockwise where it can be hooked into an indent in the cocking lever tube.

Design & Operating mechanism

The bolt rigidly engages the barrel extension—a cylindrical component welded to the receiver into which the barrel is pinned. The delay mechanism is of the same design as that used in the G3 rifle. The two-part bolt consists of a bolt head with rollers and a bolt carrier. The heavier bolt carrier lies up against the bolt head when the weapon is ready to fire and inclined planes on the front locking piece lie between the rollers and force them out into recesses in the barrel extension
When fired, expanding propellant gases produced from the burning powder in the cartridge exert rearward pressure on the bolt head transferred through the base of the cartridge case as it is propelled out of the chamber. A portion of this force is transmitted through the rollers projecting from the bolt head, which are cammed inward against the inclined flanks of the locking recesses in the barrel extension and to the angled shoulders of the locking piece. The selected angles of the recesses and the incline on the locking piece produce a velocity ratio of about 4:1 between the bolt carrier and the bolt head. This results in a calculated delay, allowing the projectile to exit the barrel and gas pressure to drop to a safe level before the case is extracted from the chamber. The delay results from the amount of time it takes for enough recoil energy to be transferred through to the bolt carrier in a sufficient quantity for it to be driven to the rear against the force of inertia of the bolt carrier and the forward pressure exerted against the bolt by the recoil spring. As the rollers are forced inward they displace the locking piece and propel the bolt carrier to the rear. The bolt carrier's rearward velocity is four times that of the bolt head since the cartridge remains in the chamber for a short period of time during the initial recoil impulse. After the bolt carrier has traveled rearward 4 mm, the locking piece is withdrawn fully from the bolt head and the rollers are compressed into the bolt head. Only once the locking rollers are fully cammed into the bolt head can the entire bolt group continue its rearward movement in the receiver, breaking the seal in the chamber and continuing the feeding cycle.
Since the 9×19mm Parabellum cartridge is relatively low powered, the bolt does not have an anti-bounce device like the G3, but instead the bolt carrier contains tungsten granules that prevent the bolt group from bouncing back after impacting the barrel extension. The weapon has a fluted chamber that enhances extraction reliability by bleeding gases backwards into the shallow flutes running along the length of the chamber to prevent the cartridge case from expanding and sticking to the chamber walls (since the bolt is opened under relatively high barrel pressure). A spring extractor is installed inside the bolt head and holds the case securely until it strikes the ejector arm and is thrown out of the ejection port to the right of the receiver. The lever-type ejector is located inside the trigger housing (activated by the movement of the recoiling bolt).

Variants

MP5A2 has a fixed stock (made of a synthetic polymer), whereas the compact MP5A3 has a retractable metal stock.
In the early 1970s HK introduced a conversion kit for the MP5 that enables it to use sporting ammunition (.22 LR). This unit consists of a barrel insert, a bolt group and two 20-round magazines. This modification reduces the cyclic rate to 650 rounds/min.
The MP5A2 and MP5A3 are available with optional four-position trigger groups; these are known as the MP5A4 and MP5A5 respectively. The trigger groups are marked with bullet pictograms rather than letters or numbers (each symbol represents the number of bullets that will be fired when the trigger is pulled and held rearward with a full magazine inserted in the weapon) and are fully ambidextrous (the selector lever is present on each side of the trigger housing). The additional setting of the fire selector, one place before the fully automatic setting, enables a two or three-shot burst firing mode.
The modular design of the MP5 offers multiple trigger groups: three-position "SEF" fire selector (positions: "S"-safe, "E"-semi automatic, "F" fully automatic. Located on left of receiver only); three-position fire selector (positions: safe, semiautomatic and a 2- or 3-round burst; selector lever is ambidextrous and its settings are marked with pictograms); four-position fire selector (positions: weapon safe, single fire, 2- or 3-round burst, full auto; ambidextrous selector; selector settings marked with pictograms); two-position fire control group (positions: weapon safe, single fire only; ambidextrous selector lever with pictograms) and a three-position fire selector group—the so-called “Navy” trigger (settings: weapon safe, semi-automatic, fully automatic fire; ambidextrous selector lever; selector settings marked with bullet symbols again). A variant with the last trigger group designated the MP5-N (N—Navy) was developed in 1986 for the United States Navy. This model has a collapsible stock, a tritium-illuminated front sight post and a 225 mm (8.9 in) threaded barrel for use with a stainless steel sound suppressor made by Knight's Armament Company together with quieter subsonic ammunition.

Micro-Uzi

The Uzi is a family of Israeli open-bolt, blowback-operated submachine guns. Smaller variants are considered to be machine pistols. The Uzi was one of the first weapons to use a telescoping bolt design which allows the magazine to be housed in the pistol grip for a shorter weapon.
The first Uzi submachine gun was designed by Major Uziel Gal in the late 1940s. The prototype was finished in 1950. First introduced to IDF special forces in 1954, the weapon was placed into general issue two years later. The Uzi has found use as a personal defense weapon by rear-echelon troops, officers, artillery troops and tankers, as well as a frontline weapon by elite light infantry assault forces.
The Uzi has been exported to over 90 countries.Over its service lifetime, it has been manufactured by Israel Military Industries, FN Herstal, and other manufacturers. From the 1960s through the 1980s, Uzi submachine guns were sold to more military and police markets than any other submachine gun ever made.

Design

The Uzi uses an open-bolt, blowback-operated design quite similar to the Jaroslav Holeček-designed Czech ZK 476 (prototype only)[6] 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.[7] 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 weapon is constructed primarily from stamped sheet metal, making it less expensive per unit to manufacture than an equivalent design machined from forgings. With relatively few moving parts, the Uzi is easy to strip for maintenance or repair. The magazine is housed within the pistol grip, allowing for intuitive and easy reloading in dark or difficult conditions, under the principle of "hand finds hand". The pistol grip is fitted with a grip safety, making it difficult to fire accidentally. However, the protruding vertical magazine makes the gun awkward to fire when prone. The Uzi features a bayonet lug.
Controls are relatively simple.[citation needed] The non reciprocating charging handle on the top of the receiver cover is used to retract the bolt. Submachine gun variants have a ratchet safety mechanism which will catch the bolt and lock its movement if it is retracted past the magazine, but not far enough to engage the sear. Semiauto civilian market versions of the Uzi usually do not have or need this feature. When the handle is fully retracted to the rear, the bolt will cock/catch on the sear mechanism and the handle can then be released to spring fully forward under power of a small spring attaching it to the topcover. It will remain forward during firing of the weapon since it does not reciprocate when the bolt is thrust backward by the force of a cartridge firing, or forward by the main action spring. The military/police versions of the Uzi will fire immediately upon chambering a cartridge as the Uzi is an open bolt weapon. This feature is extensively modified on commercial market semiauto Uzis in order to prevent fully automatic fire. The semiauto variants (whether rifle or pistol) fire from the closed bolt, with the entire bolt mechanism designed as a two-piece mechanism. The main bolt functions much like the original, but will close upon release of the charging handle. A mechanism containing part of the shape of the bolt and firing pin remains cocked to the rear. That striker like mechanism is only released forward when the trigger is pulled.
There are two external safety mechanisms on the Uzi, one being a selector lever which includes positions for "safe" which locks the sear and prevents movement of the bolt, "semi", which is one notch forward, which will allow the weapon to function in semiautomatic single shot mode, requiring the trigger to be pulled for each shot, and then "automatic" with the selector all the way forward, which will disengage part of the sear mechanism, allowing use of the trigger to control the firing mechanism. Once on automatic, the user may hold the trigger back and the weapon will fire until the magazine is empty. The bolt will then most likely come to rest on an empty chamber once the magazines is empty since the Uzi does not employ a bolt hold open on empty magazine mechanism like those found on military weapons that fire from the closed bolt. A very rare semiautomatic version made by FN Herstal and sold in Europe for a short time during the 1970s functioned exactly the same way, but the most forward setting on the selector lever was eliminated and blocked off. That variant was not approved for commercial import into the USA and was eventually withdrawn from production after having a relatively short commercial life in Western Europe and Canada.
The second external safety mechanism is a grip safety, located at the rear of the grip and meant to help prevent accidental discharge if the weapon is dropped, or the user loses a firm grip on the weapon during firing. The grip safety on the Uzi uses a stronger spring than that found on most handguns with a somewhat similar mechanism (US M1911, German Luger). The pistol grip must be firmly held by the user in order to allow the weapon to function, regardless of any manipulation of other controls.
The trigger mechanism is a conventional firearm trigger, but functions only to control the release mechanism for either the bolt (submachine gun) or firing pin holding mechanism (semiauto) since the UZI does not incorporate any internal cocking or hammer mechanism. While the system is much more mechanically simple than say, the Heckler & Koch MP5, it creates a noticeable delay from the point the user pulls the trigger and the point that the weapon actually fires. This delay is common with weapons that fire from the "open bolt".
The magazine release button/lever is located on the lower portion of the pistol grip and is intended to be manipulated by the non-firing hand. The paddle-like button lays flush with the pistol grip in order to help prevent accidental release of the magazine during soldier maneuvers and day to day activity.
Of the two stocks employed by the IDF, the wooden stock was the simpler and more robust of the two. The wooden stock is quick-detachable through the use of a release mechanism on the bottom side. Some commercial variants of the Uzi lacked the quick release mechanism and have the stock bolted in place. The second, and by far most popular stock on the Uzi was a unique folding stock which folds under the gun. It is robust but complex and was replaced by a side folding stock on the more compact models. Neither of the folding stocks can be quickly or easily removed from the weapon.
When the gun is de-cocked (the magazine must be removed or at least lowered enough to prevent feeding a round in the chamber in order to prevent the weapon from firing when it is being de-cocked), the ejector port closes, preventing entry of dust and dirt. Though the Uzi's stamped-metal receiver is equipped with pressed reinforcement slots to accept accumulated dirt and sand, the weapon can still jam with heavy accumulations of sand in desert combat conditions when not cleaned regularly.[9] The magazine must be removed prior to "decocking" the weapon or else the bolt will feed a round when being let forward and then leave the firing pin resting on an unfired primer, which can then fire if the weapon is knocked or dropped. The decocking procedure is to remove the magazine, check the chamber (which should be empty) and then pull the trigger which will release the bolt to fall on the empty chamber. The magazine may then be re-inserted. To ready the weapon for firing again, the bolt handle must be retracted to the rear. Use of the selector switch is irrelevant to this process, except that it will prevent the bolt from moving when it is in the "safe" position


variants

The Uzi Submachine Gun is a Standard Uzi with a 10-inch (250 mm) barrel. It has a rate of automatic fire of 600 rounds per minute (rpm) when chambered in 9mm Parabellum; the .45 ACP model's rate of fire is slower at 500 rpm.
The Mini-Uzi is a smaller version of the regular Uzi, first introduced in 1980. The Mini-Uzi is 600 mm (23.62 inches) long or 360 mm (14.17 inches) long with the stock folded. Its barrel length is 197 mm (7.76 inches), its muzzle velocity is 375 m/s (1230 f/s) and its effective range is 100 m. It has a greater automatic rate of fire of 950 rounds per minute due to the shorter bolt.
The Micro-Uzi is an even further scaled down version of the Uzi, introduced in 1986. The Micro-Uzi is 486 mm (19.13 in) long, reduced to 282 mm (11.10 in) with the stock folded and its barrel length is 117 mm.[13] Its muzzle velocity is 350 m/s (1148 f/s) and its cyclic rate of fire is 1,200 rpm.
The Uzi-Pro is an improved variant of the Micro-Uzi has been launched in the year 2010 by Israel Weapon Industries Ltd. (I.W.I.), formerly the Magen ("Small Arms") division of Israel Military Industries. The Uzi-Pro is a blowback-operated, select-fire, closed-bolt submachine gun with a large lower portion, comprising grip and handguard, entirely made of polymer to reduce weight; the grip section has been redesigned to allow two-handed operation and facilitate control in full-automatic fire with such a small-sized firearm. The Uzi-Pro features three Picatinny rails, two at the sides of the barrel and one on the top for optics, having the cocking handle been moved on the left side. The new weapon weighs 2.32 kg and has a length of 529 mm with an extended stock, and 30 cm while collapsed. It has been purchased by the IDF in limited numbers for evaluation and it is yet to decide whether to order additional units for all of its special forces.

Sterling submachine gun

The Sterling submachine gun is a British submachine gun which was in service with the British Army from 1944 until 1994, when it was phased out with the introduction of the L85A1 assault rifle.

History

In 1944 the British General Staff issued a specification for a new submachine gun. It stated that the weapon should not weigh more than six pounds (2.7 kg), should fire 9×19mm Parabellum calibre ammunition, have a rate of fire of no more than 500 rounds per minute and be sufficiently accurate to allow five single shots to be fired into a one foot square target at 100 yards (91 m).

To meet the new requirement, George William Patchett, the chief designer at the Sterling Armaments Company of Dagenham submitted a sample weapon of new design in early 1944. The army quickly recognised its potential (i.e. significantly increased accuracy and reliability when compared to the Sten) and ordered 120 examples for trials. Towards the end of the Second World War, some of these trial samples were used in combat by airborne troops at Arnhem and elsewhere, where it was known as the Patchett submachine gun. Given that the Patchett/Sterling can use straight Sten submachine gun magazines as well as the curved Sterling design, there were no interoperability problems.

After the war, with large numbers of Sten guns in the inventory there was little interest in replacing them with a superior design. However, in 1947 a competitive trial between the Patchett, an Enfield design, a new BSA design and an experimental Australian design was held, with the Sten for comparison. The trial was inconclusive but was followed by further development and more trials. Eventually the Patchett design won and the decision was made in 1951 for the British Army to adopt it. It started to replace the Sten in 1953 as the Sub-Machine Gun L2A1. Its last non-suppressed variation was the L2A3, but the model changes were minimal throughout its development life.
Sterling submachine guns with minor cosmetic alterations were used in the production of the Star Wars movies as blaster rifle props.

Design

The Sterling submachine gun is constructed entirely of steel and plastic and has a shoulder stock which folds underneath the weapon. Although of conventional blowback design firing from an open bolt, there are some unusual features: for example, the bolt has helical grooves cut into the surface to remove dirt and fouling from the inside of the receiver to increase reliability. The Sterling uses a much-improved (over the Sten) 34-round curved double-column feed box magazine which is inserted into the left side of the receiver. The magazine follower, which pushes the cartridges into the feed port, is equipped with rollers to reduce friction and the firing pin is designed so that it does not line up with the primer in the cartridge until the cartridge has entered the chamber.

The suppressed version of the Sterling (L34A1/Mk.5) was developed for covert operations. This version uses a ported barrel surrounded by a cylinder with expansion chambers to reduce the velocity of the bullet to prevent it from breaking the sound barrier and causing a sonic boom, along with decreasing muzzle blast and flash. This is so effective that the only sounds during firing are from the bolt reciprocating and the barely-audible explosive discharge. The Australian and New Zealand SAS regiments used the suppressed version of the Sterling during the Vietnam War. It is notable for having been used by both Argentinian and British Special Forces during the Falklands War. It was also the weapon used by Libyan agents to kill WPC Yvonne Fletcher outside the Libyan Embassy in London which sparked the 1984 siege of the building.

The Sterling has a reputation for excellent reliability under adverse conditions and, even though it fires from an open bolt, good accuracy. While it has been reported that the weapon poses no problems for left-handed users to operate,[4] it is not recommended without the wearing of ballistic eye protection. The path of the ejected cartridge cases is slightly down and backward, so mild burns can occasionally be incurred by left-handed shooters.

A bayonet of a similar design as that for the L1A1 SLR was produced and issued in British Army service, but was rarely employed except for ceremonial duties. Both bayonets were derived from the version issued with the Rifle No. 5 Mk I "Jungle Carbine", the main difference being a smaller ring on the SLR bayonet to fit the rifle's muzzle. When mounted, the Sterling bayonet was offset to the left of the weapon's vertical line which gave a more natural balance when used for bayonet-fighting.
For a right-handed shooter, the correct position for the left hand while firing is on the ventilated barrel-casing but not on the magazine, as the pressure from holding the magazine can increase the risk of stoppages, and a loose magazine can lead to dropping the weapon. The barrel-casing hold provides greater control of the weapon, so the right-hand can intermittently be used for other tasks. A semi-circular protrusion on the right hand side of the weapon, approximately two inches from the muzzle, serves to prevent the supporting hand from moving too far forward and over the muzzle.

The primary user complaint with the Sterling series is that there are projections in all directions, and carrying it on a sling frequently results in the weapon catching on clothing, load-bearing equipment, foliage, and doorways/hatches, as well as annoying (sometimes painful) poking of the user.
