The UMP (Universal Machinen-Pistole = Universal Submachine Gun) had been developed by the Heckler & Koch company of Germany in the mid- to late- 1990s and first appeared on the markets in 1999. The key idea behind the UMP was to ceate lightweight and powerful submachine gun, that also will be cheaper than one of the J&K’s flagships, the MP-5. UMP, being targeted primary for USA law enforcement market, first appeared in .45ACP and .40SW chamberings, and later – in 9mm.
The UMP is a blowback-operated select-fire submachine gun, being fired from the closed bolt. The receiver is made from the polymer, the controls are fully ambidextrous. UMP can be fired in full-auto, in single shots, and in 2 or 3 round bursts (optional). UMP also has bolt hold-open device, which traps the bolt in the open position when the last round from magazine had been fired. UMP has side-folding buttstock and two set of picatinny rails – one on the top of the receiver, and the other – on the forend. These rails can accept wide variety of sighting and other equipment, such as red-dot sights, laser pointers, tactical grips and flashlights. The barrel has quick mount for snap-on silencer.

The HK MP7 Personal Defense Weapon (PDW) is a member of a relatively new class of small arms, called Personal Defense Weapons (PDW; such specialized weapons are build since the start of WW2). The PDW are intended, as name implies, to be a defensive sidearm for second-line troops, vehicle crews and other military personnel who normally not issued with assault rifles. Previously, these troops were issued with pistols or submachine guns, but proliferation of body armor in recent years made those guns ineffective. The first firearm, intended as “the new age PDW” and offered in that class was Belgian-made FN P90, and it had special low-impulse, high-velocity ammunition, capable of penetration of current military body armor and helmets at ranges of 100 meters and beyond, while being much smaller and lighter, than assault rifle. The HK MP7, originally known simply as HK PDW, is another entry in the PDW class, and thus is a direct rival to FN P90.
The HK MP7, first announced in 2000, entered production in 2001 and, by early 2007, is officially adopted by German military, as well as some German special police units, such as KSK, and also offered for export sales. The British Military Police issues HK MP7A1 to its personnel since 2005, and it is believed that some South Korean special forces also use MP7A1.

The HK MP7 submachine gun / personal defense weapon has layout of a typical compact submachine gun (or a large pistol), with magazine being inserted into pistol grip, with folding forward grip and telescoped buttstock. The action of the MP7A1 is somewhat unusual for weapon of such small size, since it is gas operated, rotating bolt design, which strongly resembles the action of the HK G36 assault rifle, suitably scaled down. The ambidextrous fire mode selector/safety switch allows for semi-auto and full-auto modes. MP7A1 it designed to fire special, high velocity ammunition, 4.6x30mm, that looks like scaled down rifle round. That ammunition is unique to the MP7 and another HK weapon, the HK UCP / P46 pistol.
The receiver of MP7A1, along with integral pistol grip, is made from the polymer with steel reinforcements. Top side of the receiver hosts a Picatinny-type accessory rail for sight mountings. Standard sighting equipment is usually a set of low-profile open sights on quick-detachable mounts, plus a collimating (red-dot) sight Additional rails can be installed on either side of receiver, next to its front end. The MP7A1 could be fired single-handedly, or using both hands, either like the pistol or using a front grip. Telescopic buttstock can be extended to give additional stability. With buttstock and front grip are collapsed, the MP7 can be carried like any big pistol in the special holster, and can be effectively used in close combat.
The 4.6x30mm ammunition is loaded with pointed all-steel bullets with brass jacket. Bullet weight is 1.6 gram (25 grains) and the muzzle velocity is 725 m/s (ca. 2400 fps). Manufacturer claims the 100% penetration of the CRISAT body armor (1.6mm of Titanium plus 20 layers of Kevlar) at the distance of 200 meters. Other types of ammunition, including tracer, frangible, spoon-tip (rapid-tumbling for use against unarmored human targets), blank and trill (inert) also available for MP7A1; ammunition is currently manufactured in UK by BAE Systems / Radway Green plant.

The Heckler und Koch G-36 assault rifle had been born as HK-50 project in early 1990s. The reason behind that project was that the Bundeswehr (the German army), after the cancellation of the G11 and G41 projects, was left with outdated G3 rifle and no modern rifle, compatible with the current NATO standards at hands. So, the famous company Heckler & Koch was set to develop a new assault rifle for the both German army and the export. The new rifle should have been a flexible, affordable and extremely reliable design. And a modern of cause. It seems that the HK succeeds in every respects with the G36. The new 5.56mm assault rifle had been adopted by the Bundeswehr in the 1995, and in the 1999 the Spain adopted its slightly different, export version, G36E as its standard infantry rifle. The G36 also found its way into the hands of various law enforcement agencies worldwide, including British police and some US police departments. So far I’ve heard very few complaints about this rifle, and a lot of good revives and opinions. In fact, the only complaints about G36 that I know are the overheating of the handguards during the sustained fire, and the loose of zero of built in scope on some G36KE rifles, used by US police. Otherwise it is a really fine rifle, accurate, reliable, simple in operations and maintenance, and available in a wide variety of versions – from the short-barreled Commando (some even said that it’s a submachine gun) G36C and up to a standard G36 rifle and the MG36 squad automatic (light machine gun).
G36K – carbine version with standard dual scope mount and the buttstock folded
The G36, in severely modified form, also is used as a “kinetic energy” part of the US XM-29 OICW weapon. It also appears that in this form it also can be adopted by US Army as the separate XM-8 light assault rifle, to replace in the near future not so successful Colt M4 carbines, which are now in service with US military.
From the technical point of view, the G36 is a radical departure from all the previous HK rifles, based on the proven G3 roller-delayed system. The G36 is a conventional gas operated, selective fire rifle, made from most modern materials and using most modern technologies.
The receiver and most of the others external parts of the G36 are made from reinforced polymers, with steel inserts where appropriate. The operating system appears to be a modification of the older American Armalite AR-18 rifle, with its short stroke gas piston, located above the barrel, square-shaped bolt carrier and the typical rotating bolt with 7 locking lugs. Of cause, there also are many differences from the AR-18. The bolt carrier rides on a single guide rod, with the return spring around it. The charging handle is attached to the top of the bolt carrier and can be rotated to the left or to the right. When not in use, the charging handle aligns itself with the axis of the weapon under the pressure of its spring, and reciprocates with the bolt group at the top of the receiver. The gas block is fitted with the self-adjustable gas valve, that expels all the used gases forward, away from the shooter. The ejection window is located at the right side of the receiver and features a spent cases deflector to propel the ejected cases away from the face of the left-handed shooter.
All the major parts are assembled on the receiver using the cross- pins, so rifle can be disassembled and reassembled back without any tools.
The typical HK trigger unit is assembled in a separate plastic housing, integral with the pistol grip and the triggerguard. Thanks to this feature, a wide variety of firing mode combinations can be used on any rifle, simply by installing the appropriate trigger unit. Standard options are single shots, full automatic fire, 2 or 3 round bursts in any reasonable combinations. The default version is the single shots + 2 rounds burst + full auto. The ambidextrous fire selector lever also serves as a safety switch.
G36C – Compact or Commando version with open (iron) sights installed on the Picatinny rail
G36 is fed from the proprietary 30-rounds box magazines, made from translucent plastic. All magazines have special studs on its sides, so two or three magazines can be clipped together for faster reloading. The magazine housings of the G36 are made as a separate parts, so G36 can be easily adjusted to the various magazine interfaces. By the standard, the magazine release catch is located just behind the magazine, in the G3 or AK-47 style, rather than on the side of the magazine housing (M16-style). A 100-round Beta-C dual drum magazines of US origins also can be used (these magazines are standard for the MG36 squad automatic versions of the G36).
The side-folding, sturdy skeletonized buttstock is standard on all G36 rifles. It folds to the right side and does not interfere with rifle operation when folded.
The standard sighting equipment of the G36 consists of the TWO scopes – one 3.5X telescope sight below, with the second 1X red-dot sight above it. The sights are completely independent, with the former suitable for long range accurate shooting, and the latter suitable for the fast target acquisition at the short ranges. Both sights are built into the plastic carrying handle. The export versions of the G36 are available with the single 1.5X telescope sight, with the emergency open sights molded into the top of the carrying handle. The subcompact G36K Commando version is available with the integral Picatinny-type scope and accessory rail instead of the carrying handle and standard sights.
The standard G36 rifles can be fitted with the HK AG36 40mm underbarrel grenade launcher. It also can be fitted with the bayonets. Interestingly enough, G36 uses an AK-74-type bayonets, which are left from the now non-existent NVA (East Germany Army) stocks.

G3A4 – retractable butt version of the G3
During the early- to mid-1950s West Germany, like the other NATO countries, faced the need for rearming its army for the newest common 7.62x51mm NATO caliber small arms. Initially Germans preferred the Belgian FN FAL rifle, and adopted it circa 1956 under the designation of G1. Due to obvious reasons Germany wanted to manufacture its military rifles, and attempted to buy a manufacturing license for FAL, but Belgium rejected the deal. So, Germany turned to the another design, available from Spanish company CETME, and known as the CETME mod. A rifle. Germany bought the manufacturing license for CETME rifle and transferred it to the Heckler und Koch (HK) company, located in Oberndorf. HK slightly modified the CETME design, and in 1959 the Bundeswehr (W.Germany Army) finally adopted the CETME / Heckler – Koch rifle as G3 (Gewehr 3 – Rifle, [model] 3). Since that time and until the 1995 the G3 in various modifications served as a general issue shoulder weapon not only for German Armed forces, but also for many other countries. Those include Greece, Iran, Mexico, Norway, Pakistan, Portugal, Sweden, Turkey and many other countries. Total of more than 50 countries during the last 40 years issued the G3 to its forces. The G3 was or still is manufactured in countries like the Greece, Pakistan, Iran, Turkey, Portugal and others. The key reason of high popularity of the G3 is that it is much simpler and cheaper to manufacture, than its major contemporary rivals – Belgian FN FAL and US M14. To the best of my knowledge, the HK itself continued to produce and offer the G3 until the year 2000 or 2001, when it finally disappeared from HK catalogs and web-sites. However, the HK still manufactures a wide variety of firearms, based on the G3 design but of different purposes and calibers, like 9mm MP-5 submachine guns, 5.56mm HK 33 assault rifles, 5.56mm and 7.62mm HK 23 and HK 21 machine guns, PSG1 sniper rifles etc. In general, the HK G3 rifle can be described as one of the best 7.62mm NATO battle / assault rifles – reliable, versatile, controllable, non-expensive and, finally, very popular. For the civilian markets, HK produced the semi-automatic only versions of the G3, initially known as HK 41 and later – as HK 91.
G3A3 with drum type rear sight, plastic ventilated handguards and fixed stock
The G3 rifle is a selective fire, magazine fed rifle, built using delayed blowback action, developed by German engineers at Mauser Werke late in the 2nd World War and refined in Spain, at the CETME company. Initial models of the G3 rifle were quite similar to CETME rifles, and even had “CETME” markings on the receivers (until 1961 or so). The roller-delayed blowback action is described under the CETME Rifles, so I will not repeat it here. The G3 is built using as many stamped parts as possible. The receiver is stamped from sheet steel. The trigger unit housing along with pistol handle frame, also are stamped from steel and hinged to the receiver using the cross-pin in the front of the trigger unit, just behind the magazine housing. Earliest G3 rifles also featured stamped handguards and CETME-type flip-up rear diopter sights. In the mid-1960s the initial design was upgraded to the G3A3 and G3A4 configurations. These rifles had ventilated plastic handguards and a drum-type rear diopter sights, marked from 100 to 400 meters. The G3A3 was a fixed butt version, with buttstock made from plastic, and the G3A4 was a telescope butt version, with retractable metallic buttstock with rubber buttplate. Late German production G3A3 and G3A4 models were built using new trigger units, integral with restyled pistol grip and triggerguard, made from plastic. The shortest version of the G3 was the G3KA4, similar to G3A4 but with shortened barrel. Every G3 rifle can be equipped with detachable bipods, claw-type detachable scope mounts. Long-barreled versions can be fitted with bayonet or used to launch rifle grenades from the barrel. Folding cocking handle is located on the special tube above the barrel, at the left side, and does not reciprocate when gun is fired. The safety / fire selector is located above the triggerguard on the left side of the trigger group housing and usually is marked “S – E – F” (Safe – Single shots – Full auto). Latest models could have selectors marked with colored icons.

Following the revision of the OICW Block 1 / XM8 program, the Heckler & Koch company decided to enter the US military and law enforcement markets with the alternative design, which, in fact, looks quite promising. Based on the experience, gained during successful upgrade program of the British SA80 / L85A1 program, HK decided to cure the existing M16 rifles and M4 carbines from most of their problems, inherent to this 40-years old design. The key improvements, made by HK, are their patented short-stroke gas piston system, borrowed from HK G36 rifle. This system replaced the direct gas system of standard M16 rifle, so no powder residue will remain in the receiver even after long shooting sessions. The “new” gas system also is self-regulating and will work reliably with any barrel length. Other improvements include new buffer assembly, improved bolt, and a cold hammer forged barrel, as well as free-floating handguard with integral Picatinny-type rails. Originally developed as a “drop-in” upper receiver assembly for any standard M16/M4 type lower receiver, HK416 is also available as a complete weapon, with HK-made lower receivers. Current (late 2005) models include carbines with 10.5″ and 14.5″ barrels, and 16.5″ barreled carbine and 20″ barreled rifle will be added later.
Another interesting development, which is apparently based on the upscaled HK416 design, is the HK417 – the 7.62x51NATO rifle that combines AR-15/M16 type ergonomics, layout and handling with improved reliability of HK-made and designed gas piston system. This rifle probably will use HK G3-type magazines. If the rumors about HK417 are true, the 5.56mm HK416 / 7.62mm HK417 combination will be a direct rival to the newest FN SCAR system.
HK416 is a gas operated, selective fired weapon of modular design. It uses short-stroke gas piston that operates the 7-lug rotating bolt. Receiver is made from high grade aluminium alloy. Combination-type safety / fire selector allows for single shots and full automatic mode. Hk416 retains all M16-style controls, including last round bolt hold-open device, rear-based charging handle and magazine release button on the right side of the magazine well. HK416 is fitted with four Picatinny rails as standard, and may accept any type of sighting devices on STANAG-1913 compliant mounts. It also can accept modified HK AG36/AG-C 40mm grenade launcher, which is clamped directly to bottom rail. Buttstock is of typical M4 design, multi-position telescoped.

The HK33 is a 5.56 mm assault rifle developed in the 1960s by West German armament manufacturer Heckler & Koch GmbH (HK), primarily for export. Capitalizing on the success of the G3 design, the company developed a family of small arms (all using the G3 operating principle and basic design concept) consisting of four types of firearms: the first type, chambered in 7.62x51mm NATO, second – using the 7.62x39mm M43 round, third – the intermediate 5.56x45mm caliber and the fourth type – chambered for the 9x19mm Parabellum pistol cartridge.
The HK33 series of rifles were adopted by the Brazilian Air Force (Força Aérea Brasileira, FAB), the armed forces of Thailand and Malaysia where they were produced under a license agreement. The rifle was also license-built in France by MAS, and in Turkey by MKEK. The HK33 is no longer marketed by Heckler & Koch.
The HK33 is available in several configurations: the HK33A2 (fitted with a rigid synthetic stock), an accurized variant known as the HK33SG/1 (with a telescopic optical sight and improved trigger analogous to the one used in the G3SG/1), HK33A3 (with a telescoping metal stock), the HK33KA3 carbine (barrel reduced in length to the base of the front sight post also equipped with a folding metal stock; the short barrel cannot be used to launch rifle grenades or attach a bayonet) as well as the compact HK53 carbine, which features a short, 211 mm barrel, a forearm derived from the Heckler & Koch MP5 submachine gun and a telescoping stock or a receiver endplate cover (later models also received an open-style flash hider).

The HK13 light machine gun was also built based on the HK33. It is fed from either box or drum magazines (the latter has a 100-round capacity), has a quick-change heavy barrel for sustained fire, shrouded with a sheet metal heat guard (replacing the synthetic forearm) and a 2-point bipod adapter.
Heckler & Koch also make a semi-automatic only variant of the HK33A2 for the civilian shooting market designated the HK93.
The rifle is disassembled into the following components for maintenance: the receiver, stock with return spring and trigger pack with pistol grip. The trigger groups can be swapped out to meet the user’s specific mission requirements. HK offers several different trigger assemblies: a three-shot burst fire control group with selector lever/safety (selector settings: “0” – weapon is safe, “1” – single fire, “2” – 2-round burst or “3” – burst, 3-rounds; the selector lever is ambidextrous); a “Navy” trigger unit (three settings: safe, semi and full auto fire) and a four-position trigger group (selector settings: weapon safe, single fire, 3-round burst and automatic fire).
