The Heckler & Koch MP5 (from German:
Maschinenpistole 5, "machine pistol model 5") is a 9mmsubmachine gun of German design, developed in the 1960sby a team of engineers from the German small armsmanufacturer Heckler & Koch GmbH (H&K) of Oberndorf
am Neckar. There are over 100 variants of the MP5,[4]
including a semi-automatic version.
The MP5 is one of the most widely used submachine guns in
the world,[5] having been adopted by 40 nations andnumerous military, law enforcement, intelligence, and
security organizations.[3]

History
Heckler & Koch,encouraged by the successof the G3 automatic rifle,developed a family ofsmall arms consisting offour types of firearms allbased on a common G3design layout andoperating principle. Thefirst type was chamberedfor 7.62×51mm NATO,the second for the7.62×39mm M43 round,the third for theintermediate 5.56×45mmNATO caliber, and thefourth type for the9×19mm Parabellumpistol cartridge. The MP5was created within the
fourth group of firearms and was initially known as theHK54.
Work on the MP5 began in 1964 and two years later it wasadopted by the German Federal Police, border guard andarmy special forces.
The MP5 is manufactured under license in several nationsincluding Greece (formerly at EBO – Hellenic ArmsIndustry, 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).[7]
Design details
The primary version of the MP5 family is the MP5A2,which is a lightweight, air-cooled, selective fire delayedblowback operated 9×19mm Parabellum weapon with aroller-delayed bolt. It fires from a closed bolt (bolt forward)position.

A view through the weapon's
aperture sight
The fixed, free floating, cold hammer-forged barrel has 6right-hand grooves with a 1 in 250 mm (1:10 in) rifling twistrate and is pressed and pinned into the receiver.
Features
The first MP5 models used a double-column straight boxmagazine, but since 1977, slightly curved, steel magazinesare used with a 15-round capacity (weighing 0.12 kg) or a30-round capacity (0.17 kg empty).
The adjustable iron sights(closed type) consist of arotating rear diopter drumand a front post installed ina hooded ring. The rearsight is adjustable for bothwindage and elevationwith the use of a specialtool, being adjusted at thefactory for firing at 25mwith standard 124 grainsFMJ 9x19mm NATOammunition; the drum
provides four different apertures of varying width used toadjust the light entrance in the diopter system, according tothe user's eye relief and tactical situation, and not for firing at25, 50, 75 and 100m as some people wrongly imagine.
The MP5 has a hammer firing mechanism. The trigger groupis 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 safetytoggle. The “S” or Sicher position in white denotes weaponsafe, “E” or Einzelfeuer in red represents single fire, and“F” or Feuerstoß (also marked in red) designatescontinuous fire. The SEF symbols appear on both sides ofthe plastic trigger group. The selector lever is actuated withthe thumb of the shooting hand and is located only on the leftside of the original SEF trigger group or on both sides of theambidextrous trigger groups. The safety/selector is rotatedinto the various firing settings or safety position bydepressing the tail end of the lever. Tactile clicks (stops) arepresent at each position to provide a positive stop andprevent inadvertent rotation. The "safe" setting disables thetrigger by blocking the hammer release with a solid sectionof the safety axle located inside the trigger housing.

The non-reciprocating cocking handle is located above thehandguard and protrudes from the cocking handle tube atapproximately a 45° angle. This rigid control is attached to atubular piece within the cocking lever housing called thecocking lever support, which in turn, makes contact with theforward extension of the bolt group. It is not howeverconnected to the bolt carrier and therefore cannot be usedas a forward assist to fully seat the bolt group. The cockinghandle is held in a forward position by a spring detentlocated in the front end of the cocking lever support whichengages in the cocking lever housing. The lever is lockedback by pulling it fully to the rear and rotating it slightlyclockwise where it can be hooked into an indent in thecocking lever tube.
Operating mechanism
The bolt rigidly engages the barrel extension—a cylindricalcomponent welded to the receiver into which the barrel ispinned. The delay mechanism is of the same design as thatused in the G3 rifle. The two-part bolt consists of a bolthead with rollers and a bolt carrier. The heavier bolt carrierlies up against the bolt head when the weapon is ready tofire and inclined planes on the front locking piece liebetween the rollers and force them out into recesses in the
barrel extension.[8]
When fired, expanding propellant gases produced from theburning powder in the cartridge exert rearward pressure onthe bolt head transferred through the base of the cartridgecase as it is propelled out of the chamber. A portion of thisforce is transmitted through the rollers projecting from thebolt head, which are cammed inward against the inclinedflanks of the locking recesses in the barrel extension and tothe angled shoulders of the locking piece. The selectedangles of the recesses and the incline on the locking pieceproduce a velocity ratio of about 4:1 between the boltcarrier and the bolt head. This results in a calculated delay,allowing the projectile to exit the barrel and gas pressure todrop to a safe level before the case is extracted from thechamber.
The delay results from the amount of time it takes for enoughrecoil energy to be transferred through to the bolt carrier in asufficient quantity for it to be driven to the rear against theforce of inertia of the bolt carrier and the forward pressureexerted against the bolt by the recoil spring. As the rollersare forced inward they displace the locking piece and propel

the bolt carrier to the rear. The bolt carrier's rearwardvelocity is four times that of the bolt head since the cartridgeremains in the chamber for a short period of time during theinitial recoil impulse. After the bolt carrier has traveledrearward 4 mm, the locking piece is withdrawn fully from
the bolt head andthe rollers arecompressed intothe bolt head.Only once thelocking rollers arefully cammed into the bolt head can the entire bolt group continue itsrearward movement in the receiver, breaking the seal in the chamber andcontinuing the feeding cycle.
Since the 9×19mm Parabellum cartridge is relatively low powered, thebolt does not have an anti-bounce device like the G3, but instead the boltcarrier contains tungsten granules that prevent the bolt group frombouncing back after impacting the barrel extension. The weapon has afluted 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 fromexpanding and sticking to the chamber walls (since the bolt is opened under relatively high barrel pressure). Aspring extractor is installed inside the bolt head and holds the case securely until it strikes the ejector arm and isthrown out of the ejection port to the right of the receiver. The lever-type ejector is located inside the triggerhousing (activated by the movement of the recoiling bolt).
Accessories
Three lugs are provided at the muzzle that are used to work with certain muzzle devices made by Heckler & Koch,including: a slotted flash suppressor, blank firing attachment (marked with a red painted band denoting use withblank ammunition only), an adaptor for launching rifle grenades (for use with rifle-style grenades with an insidediameter of 22 mm using a special grenade launching cartridge) and a cup-type attachment used to launch tear gasgrenades.
The receiver housing has notches that permit the attachment of a standard Heckler & Koch quick-detachablescope mount (also used with the G3, HK33 and G3SG/1) that can be used to mount daytime optical sights(telescopic 4x24), night sights or a halogen underbarrel weaponlight. It can be used with reflex sights and laserpointers. The mount features two spring-actuated bolts, positioned along the base of the mount, which exertpressure on the receiver to hold the mount in the same position at all times assuring zero retention. All versions ofthe quick-detachable scope mount provide a sighting tunnel through the mount so that the shooter can continue touse the fixed iron sights with the scope mount attached to the top of the receiver.
Laser Products has a replacement handguard incorporating a Sure-Fire Model 628 tactical 15,000-candlepower(65 lumen) quartz-halogen flashlight. It is powered by two 123A 6-volt lithium batteries for a battery life of aboutan hour of use. It is operated either by a squeeze-activated pressure tape switch on the right side for briefillumination or a rocker on/off switch on the left side for continuous illumination. It can be turned on just long enoughfor positive, close-range target discrimination and acquisition at night or used to illuminate or blind targets in lowlight conditions.

The Heckler & Koch MP5 is widely
used by military, law enforcement,
security and other such forces. Seen
here is the MP5A2 variant with the
early 'slimline' handguard and a fixed
stock.
Variants
The MP5A2 has a fixed buttstock (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 thatenables it to use sporting ammunition (.22 LR). This unit consists of abarrel insert, a bolt group and two 20-round magazines. Thismodification reduces the cyclic rate to 650 rounds/min.
The MP5A2 and MP5A3 are available with optional four-position triggergroups; these are known as the MP5A4 and MP5A5 respectively. Thetrigger groups are marked with bullet pictograms rather than letters ornumbers (each symbol represents the number of bullets that will be firedwhen the trigger is pulled and held rearward with a full magazine insertedin the weapon) and are fully ambidextrous (the selector lever is presenton each side of the trigger housing). The additional setting of the fireselector, one place before the fully automatic setting, enables a two orthree-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 withpictograms); 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 selectorlever; 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 UnitedStates 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 withquieter subsonic ammunition.
Plastic training variants
H&K offers dedicated training variants of these weapons, designated MP5A4PT and MP5A5PT (PT—PlasticTraining), modified to fire a plastic 9×19mm PT training cartridge produced by Dynamit Nobel of Germany. Theseweapons operate like the standard MP5 but have a floating chamber and both rollers have been omitted from thebolt to function properly when firing the lighter plastic projectiles. To help identify these weapons blue dots werepainted on their cocking handles and additional lettering provided. The PT variant can be configured with variousbuttstocks and trigger groups and was developed for the West German Police and Border Guard.
Semi-auto only variants
The MP5SFA2 (SF – single-fire) is the same as the MP5A2 but is fitted with an ambidextrous semi-automatic onlytrigger group. Versions delivered after December 1991 are assembled with select-fire bolt carriers allowing fullyautomatic operation when used with the appropriate trigger module. Developed in 1986 in response to the

The two-position trigger unit was usedin the single-fire HK94 carbine that wasproduced specifically for the civilianmarket with a 420 mm (16.5 in) barrel.
Suppressed variants
In 1974 H&K initiated design work on a sound-suppressed variant of the MP5,designated the MP5SD (SD—Schalldämpfer German for "sound suppressor"),which features an integral but detachable aluminium sound suppressor and alightweight bolt. The weapon's 146 mm (5.7 in) barrel has 30 2.5 mm (0.1 in)ports drilled forward of the chamber through which escaping gases are divertedto the surrounding sealed tubular casing that is screwed on to threading on thebarrel’s external surface just prior to the ported segment. The suppressor itself isdivided into two stages; the initial segment surrounding the ported barrel serves as an expansion chamber for thepropellant gases, reducing gas pressure to slow down the acceleration of the projectile. The second,decompression stage occupies the remaining length of the suppressor tube and contains a stamped metal helixseparator with several compartments which increase the gas volume and decrease its temperature, deflecting thegases as they exit the muzzle, so muffling the exit report. The bullet leaves the muzzle at subsonic velocity, so it doesnot generate a sonic shock wave in flight. As a result of reducing the barrel’s length and venting propellant gasesinto the suppressor, the bullet’s muzzle velocity was lowered anywhere from 16% to 26% (depending on theammunition used) while maintaining the weapon’s automation and reliability. The weapon was designed to be usedwith standard supersonic ammunition with the suppressor on at all times.
The MP5SD is produced exclusively by H&K in several versions: the MP5SD1 and MP5SD4 (both have areceiver end cap instead of a buttstock), MP5SD2 and MP5SD5 (equipped with a fixed synthetic buttstock) andthe MP5SD3 and MP5SD6 (fitted with a collapsible metal stock). The MP5SD1, MP5SD2 and MP5SD3 use astandard "SEF" trigger group (from the MP5A2 and MP5A3), while the MP5SD4, MP5SD5 and MP5SD6—atrigger module with a mechanically limited 3-round burst mode and ambidextrous selector controls (from theMP5A4 and MP5A5). A suppressed version was produced for the U.S. Navy – designated the MP5SD-N, whichis a version of the MP5SD3 with a retractable metal stock, front sight post with tritium-illuminated dot and astainless steel suppressor. This model has a modified cocking handle support to account for the slightly largeroutside diameter of the suppressor. The design of the suppressor allows the weapon to be fired with water inside,should water enter the device during operation in or near water.
MP5K
In 1976 a shortened version of the MP5A2 was introduced; the MP5K (K from the German word Kurz = "short")was designed for close quarters battle use by clandestine operations and special services. The MP5K does nothave a shoulder stock (the receiver end was covered with a flat end cap, featuring a buffer on the inside and a slingloop on the outside), and the bolt and receiver were shortened at the rear. The resultant lighter bolt led to a higherrate of fire than the standard MP5. The barrel, cocking handle and its cover were shortened and a vertical foregrip

A Turkish gendarme with an MP5 at

was used to replace the standard handguard. The barrel ends at the base of the front sight, which prevents the useof any sort of muzzle device.
The MP5K is produced (by Heckler & Koch and under license in Iran and Turkey) in four different versions: theMP5K, MP5KA4, MP5KA1, MP5KA5, where the first two variantshave adjustable, open-type iron sights (with a notched rotary drum), andthe two remaining variants – fixed open sights; however, the front sightpost was changed and a notch was cut into the receiver top cover. TheMP5K retained the capability to use optical sights through the use of anadapter.
A civilian semiautomatic derivative of the MP5K known as the SP89was produced that had a foregrip with a muzzle guard in place of thevertical grip.
In 1991 a further variant of the MP5K was developed, designated theMP5K-PDW (PDW—Personal Defense Weapon) that retained thecompact dimensions of the MP5K but restored the fire handlingcharacteristics of the full-size MP5A2. The MP5K-PDW uses a side-folding synthetic shoulder stock (made by the U.S. company ChoateMachine and Tool), a “Navy” trigger group, a front sight post with abuilt-in tritium insert and a slightly lengthened threaded, three-lug barrel(analogous to the MP5-N). The stock can be removed and replacedwith a receiver endplate; a rotary drum with apertures from the MP5A2can also be used.
Larger caliber versions
In 1991, Heckler & Koch introduced the MP5/10 (chambered in 10mmAuto) and MP5/40 (chambered for the .40 S&W cartridge), which arebased on the MP5A4 and MP5A5. These weapons were assembled infixed and retractable stock configurations (without a separatedesignation) and are fed from translucent 30-round polymer box
magazines.[9] These weapons include a bolt hold-open device, whichcaptures the bolt group in its rear position after expending the lastcartridge from the magazine. The bolt is then released by pressing a leverpositioned on the left side of the receiver. Both weapons use a barrelwith 6 right-hand grooves and a 380 mm (1:15 in) twist rate, and like theMP5-N, both have a 3-lugged muzzle device and a tritium-illuminatedfront sight aiming dot.
Problems with the MP5/10 and MP5/40 led to the development of theHeckler and Koch UMP.

differences were that it had a longer and heavier bolt carrier than the MP5 and a flip up "ladder"-style rearsight rather than the MP5's aperture sight. Its original 30-round
steel magazines were straight rather than curved, had a plastic
follower, and were reinforced with ribs.
MP5: A slightly modified version of the HK54 first created in
1966. It has a matte-black phosphated finish instead of the grayish
finish. It originally had the narrow checkered metal "Slimline"
handguards in the place of the HK54's narrow slotted metal ones.These were later replaced by the thicker "Tropical" handguards.
The proprietary Heckler & Koch "claw mount" base for mounting
optical and electronic scopes was added around 1973. The
improved 15- and 30-round magazines were adopted in 1977;
they were curved, had unribbed sides, and had chromed-steel
followers.

mounting a quick-detachable Qual-A-Tec suppressor, and an ambidextrous "Navy" 4-position trigger
group with a 3-round burst mode. A shoulder cross-draw or thigh quick-draw holster is available.MP5SD: An MP5 model with an integrated suppressor (Schalldämpfer) created in 1974.

produced from 1992 to 2000.
MP5/40: Chambered in .40 S&W, available in various stock/trigger group configurations. It was produced

Civilian-Market Versions
HK94: American import model of the MP5 with an exposed 16.54-inch [420mm] barrel and special SF
(safe/semi-automatic) trigger group, designed for civilian use.
A barrel-mounted vertical foregrip and a ventilated barrel shroud were available for the stock HK94.(Arnold Schwarzenegger used a HK94A3 converted to fire full auto and modified with these accessories in
the movie Raw Deal (1986); it is even featured in the poster art).
The HK94 was made from 1983 to 1989, in three different configurations:
The HK94A2 had a fixed stock, an overall length of 34.59 inches [829 mm], and weighed 6.43 lbs.
[2.92 kg.]. In 1991, the state of California imported 420 HK-94A2s, mostly for their state
Department of Corrections; it was the last batch of HK-94s imported into the United States.
The HK94A3 had a retractable stock, an overall length of 27.58 inches [700 mm] collapsed and
34.05 inches [865 mm] extended and weighed 7.18 lbs. [3.26 kg].The HK94/SG-1 (ScharfschutzenGewehr, "sharp-shooting rifle") was designed for short-range
sniping in built-up areas like cities or prisons. It proved to be unsuitable for its designed purpose, due
to its poor penetration and stopping power, and most went to target shooters and collectors. It had a
fixed match stock with a rubber buttpad and an adjustable cheekpiece, folding bipod, flash hider, and
a 6 x 42mm Leupold VIII Adjustable Objective scope. It had an overall length of 40.39 inches
[1026mm] and a weight of 9.25 lbs. [4.2 kg]. Its Mean Standard Retail Price (MSRP) in 1986 was
US$ 1,525; this was more than twice what a stock HK94A2 (US$ 650) or HK94A3 (US$ 720)cost. Only 50 were imported into the United States; authentic models have serial numbers running in
the 43XX range.
As an aftermarket modification, a PSG-1 trigger pack with target pistol grip and match trigger could
be added by a gunsmith by changing the ejector and hammer spring. The 6x Leupold scope was
calibrated for .223 Remington rounds, so other scopes were often substituted.
SP89: Sport Pistole M1989. Semi-automatic only version of the MP5K designed for civilian use. It had a
modified vertical foregrip redesigned into a traditional handguard to make it compliant with the Semi-AutoWeapons Ban of 1989. It was made from 1989 to 1994.
