Since World War II, the German concern of Heckler und Koch has become one of Europe’s largest and most important small-arms manufacturers. Its success has been based soundly on the production of its G3 rifle, which was a standard NATO weapon and is still in use all over the world. In the 1960s the company used the G3 as a basis on which to produce the Heckler and Koch MP5 sub-machine gun.
The MP5 was designed to fire the standard 9-mm X 19 Parabellum cartridge. Although this is a relatively low-powered pistol round, the MP5 uses the same roller and inclined ramp locking mechanism as the G3, which fires a full-power rifle round. The complexity of the system is more than offset by its increased safety. Unlike other machine pistols, the MP5 fires from a closed bolt- the brench block is in the forward position when the trigger is pulled so there is no forward-moving mass to disturb the aim. This makes the MP5 much more accurate than other SMGs. The resemblance to the G3 is maintained by the use of many G3 components on the MP5.
Used by military and law enforcement units in more than 50 nations, the MP5 is firmly established as the world’s pre-eminent sub-machine gun. Over 120 variants of the MP5 are available to address the widest range of tactical requirements. The weapon’s unique modular design and a variety of optional buttstocks, forearms, sight mounts, and other accessories gives the MO5 extraordinary flexibility to meet almost any mission. The main versions of the MP5 include the MP5A with a fixed butt stock and the MP5A3 with a sliding metal strut stock. The MP5A4 and the MP5A5 are the same weapons with the addition of a three-round burst fire capability.
The MP5SD is as silenced weapon for use in special or anti-terrorist warfare. The removable sound suppressor is integrated into the design and conforms to the normal length and profile of an unsuppressed weapon. The MP5SD uses an integral aluminum or optional wet technology stainless steel sound suppressor. Unlike most silenced weapons, it does not require use of subsonic ammunition for effective sound reduction.
The MP5K was introduced for use by special units, where weapon concealment is often essential. It is a very short version of the basic MP5, only 325 mm long and recognizable by a small foregrip, under the almost non-existent muzzle. The MP5KA1 is a special version of this variant with no protrusions so than it can be carried under clothing or in a special holster.
The MP5N or ‘Navy’ model is made for US Navy SEALs. Fully ‘marinated’ for operations in seawater, it comes standard with an ambidextrous trigger group and threaded barrel.
In spite of its complexity, the MP5 has proved to be an excellent and reliable submachine-gun. Its first users were West German police agencies and border guards, and soon numbers were purchased by Swiss police and the Netherlands armed forces. Single fire variants are widely used by law-enforcement officers in crowded public areas such as airports.
However, it is since the MP5 was adopted by the British SAS that it has become the weapon of choice for Special Forces worldwide. The MP5 is inherently accurate because it fires from a closed bolt, and pinpoint accuracy is an essential requirement of any weapon used in a hostage rescue, where innocent lives are at risk.
