The Heckler & Koch MP5 (Maschinenpistole 5 - Submachine Gun, Model # 5) is a German family of submachine guns that were created by Heckler & Koch in the 1960s, based on a previous HK G3 development. Currently, the HK MP5 is one of the most common post-war submachine guns in the world, second in distribution and recognition, perhaps, only to the Israeli Uzi. Initially, it was created for the needs of the border guard of the Federal Republic of Germany, but rather quickly began to be used also in the German police, special forces of the Bundeswehr, in customs, etc.
The MP5 submachine gun automatics operates on the principle of a semi-free shutter, fire from the weapon is conducted from the closed shutter. Trigger trigger type, it provides shooting in a single and automatic mode. The fuse also serves as a fire mode interpreter at the same time. On the weapon it is located on the left side near the fire control handle. When the fuse is locked, the trigger and trigger are blocked, which is intended to ensure the safety of handling the weapon. Locking the bolt of the submachine gun in the forward position is carried out with the help of rollers, which simultaneously play the role of the accelerator of the bolt. This design, proposed by German gunsmiths, allowed to increase the accuracy of shooting. The weapon was mounted sight drum type: open or diopter (selected by turning the rear sight drum).
Since 1972, this model of the submachine gun has been shipped abroad, becoming, along with the G3 rifle, the export bestseller of Heckler & Koch. The weapon is adopted by police officers and special forces in more than 40 countries around the world. The reason for this popularity was not only the traditionally high German quality, accuracy, small dimensions and weight, but also the unification with the G3 assault rifle. Also, the submachine gun has managed to earn a reputation as an indestructible weapon, distinguished by outstanding reliability (with proper handling and care).
Thanks to the film industry and the computer games industry, this model of firearms has become truly iconic. Today it is difficult to find an American fighter or first-person shooter in which the MP5 submachine gun would not have been presented. Such popularity and fame of weapons pushed manufacturers to release self-loading civilian versions. The most famous at this time are the German SP 89, HK 94, Beitler Waffentechnik BWT 5, Oberlandarms OA5, Pakistani POF-4 and POF-5, Turkish T-94 ZSG, Swiss BT 96, in the campaign, in the campaign, in the campaign, in the campaign, in the campaign, in the template, in the template, in the template, in the template, in the template, in the figure, in the template, in the template, in the index of the X. 10. The appearance on the Russian market of a national civilian copy of the popular all over the world submachine gun was a matter of time.
In Russia, the Russian Arms Company from the city of Tarusa, Kaluga Region, began producing civilian copies of popular weapons. This company has been operating in the Russian civilian market since 2009. The company has the appropriate licenses for trade and production of weapons and ammunition, and, as indicated on its official website, works only with wholesale buyers. Initially, the company specialized in selling copies of historical weapons - blasting pistols, muskets, sabers and bayonets, as well as related accessories. There are in its assortment and weight and size models, as well as decommissioned weapons (cooled samples). All this is perfectly combined with the strategy of the Russian Arms Company LLC - working in the underdeveloped niches of the Russian arms market. In 2014, the company's specialists for the first time in the Russian Federation certified the mass production of copies of long-barreled firearms. In addition, she is engaged in the release of a hunting carbine RA-5 caliber 9х19 and a traumatic Stalker pistol. Also in 2014, the company successfully launched the production of 9mm PA traumatic cartridges.
Although the manufacturer officially calls the RA-5 a hunting carbine, online media reporters all4shooters.сom believe that this is not the main purpose of these weapons. Although it may be suitable for hunting medium and small animals at relatively short distances to 100 meters. Much more fans of the Russian copy of the MP5 submachine gun can be found among fans of recreational shooting (because of the relatively low price of ammunition), shooters-athletes involved in practical shooting, and collectors of copies of military weapons. In addition, the carbine may not be bad for home self-defense. It is worth noting that a similar model of Turkish production MKE T-94 SD A2, which is currently sold in Russia, is also declared as a hunting semi-automatic carbine. Only persons owning a license for a long-barreled rifled hunting weapon can purchase them.
The MP5 submachine gun is a kind of “champion” in the speed of opening fire, this feature makes the RA-5 especially interesting for shooters, representatives of security and security structures. This fact was at one time established by associate professor A. V. Stoltov, a researcher at the M. Kalashnikov Institute of Small Arms, who at one time spent a sufficient number of comparative experiments to determine the time needed to apply a weapon, remove the fuse, send the cartridge in the chamber, aiming, etc. He compared various modern models of automatic small arms: AK-74, M16, MP5, AUG and others. Studies have shown the fact that the shortest reaction time is inherent in the German MP5 submachine gun. For example, in an AK-74 vs. MP5 duel, the shooter with German weapons managed to make 3-5 shots before the shooter, armed with a Kalashnikov, was ready to open fire.
The self-loading hunting carbine RA-5 is the embodiment of the design of the famous German submachine gun, or rather its version MP5SD. The weapon is equipped with an integrated device for flameless and silent firing (lowers the sound pressure level to 70 dB). In addition to having only a single firing mode, the RA-5 differs from its combat equivalent by the presence of Picatinny slats, which are located on the upper part of the receiver, as well as on the shank: in the lower part, on the left and on the right side, as well as in a reduced capacity magazine On 10 cartridges (this is a shortened version of the store in accordance with the requirements of the Russian legislation), a standard-size store is also available to consumers, but in this case a capacity limiter will be installed in it.
At one time, the MP5SD submachine gun was created based on the design of the MP5A2 model. The weapon was originally intended for use by members of the police and army special forces. The new submachine gun was presented in three main versions - with a fixed or folding butt, or no stock at all (models MP5SD2, MP5SD3 and MP5SD4, respectively). The hunting rifle RA-5 is available to Russian consumers only with a permanent butt. From the usual MP5 submachine guns, the MP5SD variant was distinguished by the presence of an integrated silencer. Shooting from it was conducted by the same 9x19 Parabellum cartridges, which have a supersonic initial speed of a bullet. In order to reduce the initial speed to a subsonic level, in the walls of the MP5SD barrel, 30 holes were made, which are intended to divert a portion of the powder gases into the expansion chamber of the muffler.
At the same time, the muzzle device, which is installed on the Russian carbine RA-5, is in fact not an integrated silencer, since it does not have holes that reduce the speed of a bullet in the barrel. In the RA-5 model, the manufacturer indicates the value of the muzzle energy at the level of 570 J, which for the standard bullet 9x19 mm corresponds to the supersonic initial speed of its flight — more than 370 m / s. Whereas for models MP5SD indicators are respectively 380 J and 285 m / s. This is where the main differences between the models end.
Both the MP5 submachine gun and the Russian civilian version of the RA-5 use the 9x19 mm Parabellum cartridge, which is the most popular in the weapons world, or simply the 9x19 Para. Currently, the name 9x19 mm Para points only to the geometric dimensions of the cartridge, but there are more than two thousand different versions of it in the world. The sleeve of this cartridge can be bimetallic, steel, brass, plastic, and the bullet can be of any type, including plastic. The range of the Russian Armory Company includes traumatic cartridges of this caliber with an elastic striking element - a ball made of a thermoplastic elastomer, which has several advantages over rubber bullets. For example, it does not lose elasticity at temperatures up to -70 degrees Celsius. Ammunition of this caliber is produced in Russia in a variety of ways. For example, 9X19 PSO is a sports cartridge, which is serially produced by the Tula cartridge factory. The mass of his bullet - 7,46 g, the initial flight speed - 340 m / s.
