In recent years, there is an active development of various systems of class rifle PDW (Personal Defense Weapon - «Personal self-defense weapon"). Weapons with a relatively small size and relatively high firepower is of interest to a wide range of customers. The main operators of such weapons are considered the crews of combat vehicles, commanders and other military or security forces, who are unable to effectively use the "full-size" machines or rifles. Concept PDW to date has gained popularity, and most of the major manufacturers of small arms has "noted" in this field.
Was no exception and the American company Knight's Armament Co. (KAC), known for its original designs. The first studies related to the concept of PDW, firm KAC held back in the eighties, but then all work stopped at the stage of studying the prospects of new weapons. Later KAC repeatedly returned to the idea of creating his version of PDW, but with little success this weapon had not come out of the testing stage. The first "full" its draft PDW company introduced only in 2006. New weapons received plain name, fully revealing its essence, - KAC PDW.
Characteristics of KAC PDW does not allow one to classify it as a submachine gun or assault rifle. However, some features of this weapon permit to carry it as a sub-machine gun, and to the vending machines. But in view of the similarities and some of the external features to be found in the future will be called KAC PDW machine, not forgetting, however, that this rifle system is a "personal weapon of self-defense." characteristic feature of almost all types of weapons are the original class PDW ammunition, is a "hybrid" pistol and intermediate cartridge. In order to provide the desired characteristics of the fire combined with the small size and weight reduced gunsmiths caliber bullets, while maintaining a relatively high initial velocity and muzzle energy. For an automaton KAC PDW was also elected a new original cartridge - 6x35 mm TSWG. 6x35 mm cartridge TSWG was developed in the first half of two-thousand years by Hornady. This ammunition has a relatively short sleeve bottle-shaped length of 35 mm, made from brass. Insert the total weight of 10.1 g is equipped with bullet caliber 6 mm weight 4.2 g According to some reports, the cartridge TSWG in the base configuration comes with a lead bullet shell expansive action. Due to this, with a small caliber should provide a high damaging effect. At distances of up to 200-300 m chuck 6x35 mm TSWG a number of characteristics is not inferior to the standard intermediate munition NATO 5,56h45 mm.
Automatic KAC PDW was designed chambered TSWG, and its design is based on some of the technical solutions specific to automatic weapons the United States. Thus, the receiver box weapon is divided into two parts, as in the M16 rifle and M4. In the upper part of the box is fastened barrel and shutter mechanisms arranged. At the bottom is a trigger mechanism and receiving mine shop. The lower part of the receiver is made on the basis of the relevant parts rifle M16. Like the bulk of modern machines KAC PDW uses the vapor-automatic. Above the barrel has two vent pipes and two gas pistons. According to some reports, the two gas engines are used to improve the reliability of automation by using a relatively low-power cartridge, giving a small amount of powder gases. The gate frame and the return spring located at the top of the receiver. An interesting feature of the machine steel KAC PDW some features characteristic of non-US automatic rifle, but the weapon of the Soviet / Russian design. Thus, the barrel locking it happens rotating bolt weapon whose design greatly resembles the corresponding units of Kalashnikov assault rifles. On Arms series "AK" brings to mind the location of the return spring: it is completely hidden inside the receiver. automatic KAC PDW is equipped with a rifled barrel length of 10 or 8 inches (254 and 203.2 mm). On the outer surface of the barrel there are numerous hemispherical recess. It is argued that this makes it easier to trunk, as well as improve its cooling of the weapon. Mounted on the trunk of the muzzle compensator, designed specifically for machine KAC PDW into account the characteristics of the cartridge 6x35 mm TSWG. trigger mechanism is located at the bottom of the receiver. He can fire a single shot, and queues. Pins interpreter fire are on both sides of the receiver, above the pistol grip, and are designed to switch the thumb. Translator fire has three positions: lock mechanisms, single and automatic fire.
Feed system for automatic Knight's Armament Co. PDW uses original detachable box magazine 30 rounds. By design, they resemble standard shops NATO Ammo 5,56h45 mm, but are noticeably smaller. Shop is placed in a foster mine machine, just reminding used on American automatic rifles. The magazine release is unified with existing weapons. placement of all units inside the receiver allowing for a folding butt weapons. If necessary, it pivots on a hinge and is placed along the right side of the machine. The location of the triangular frame of the butt does not prevent the use of weapons or ejection of spent cartridges. According to recent trends automatic KAC PDW has several universal Picatinny straps that allow it to equip a variety of optional equipment. So, on the upper surface of the arms has a long bar with almost the receiver. In the base plate is installed on this standard diopter sight and front sight. If necessary, they can be replaced by any other sighting devices, allowing installation on universal mount. automatic KAC PDW does not express the forearm. Instead, the weapon has extended forward perforated barrel shroud, is integral to the receiver. On the lateral surfaces of two housing mounted Picatinny rail, which can be closed with plastic caps. The fourth plate is located under the barrel and the casing may also be closed by a lid. On most published images machine is equipped with front "tactical" handle mounted on the bottom plate."personal defense weapon» KAC PDW by type, destination, and some characteristics similar to automatic rifles and machine guns. At the same time it has a much smaller size and weight. Thus, the length of the KAC PDW with a 10-inch barrel with folded butt equals 495 mm. When buttstock length exceeds 730 mm. Using a barrel length of 8 inches further reduces the size of weapons. KAC PDW (10-inch barrel) without ammunition weighs only 1.95 kg. Sided store increases the weight of weapons by about 400 g Thus, automatic gun with 3-4 stores weighs no more than 3.5-4 kg, in combination with the small size makes it easy to carry and use. vapor-automatic weapons provides rate of up to 700 rounds per minute. If you are using a 10-inch barrel Muzzle velocity exceeds 740 m / s. Effective range of weapons - 300 m. Alleged that when shooting at such distances KAC PDW is not inferior to other modern American small systems using cartridge 5,56h45 mm. KAC PDW rifle range was first introduced in 2006 and since then has been repeatedly demonstrated at various gun shows. Weapons offered to customers in two configurations, differing in length of the barrel. In promotional materials, emphasis is given to the favorable ratio of the size of weapons and firepower. In particular, it was argued that the folded KAC PDW does not interfere with the soldier off fighting machine, but allows you to immediately start a firefight with the enemy. However, it seems the project Knight's Armament Co. PDW suffered the same fate as many other original developments in the field of small arms, including the class of Personal Defense Weapon. Since the first demonstration of the machine KAC PDW has been eight years, but has not yet appeared no reliable information on the purchase of weapons by the armed forces or security forces. According to some reports, police departments of several states of the USA were interested in the KAC PDW, and even expressed a desire to test these weapons in practice. However, up to now the KAC PDW and chuck 6x35 mm TSRW never put into service.Admittedly, weapons KAC PDW is of particular interest from a technical point of view. Engineers Knight's Armament Co. Failed to create a weapon with firepower, close to automatic rifles, in the size of a submachine gun. In addition to the characteristics of this system is also worth noting an interesting approach to linking units weapons. By its architecture reminds KAC PDW was in service with the M16 rifle and M4, which is probably due in some measure to simplify the preparation of the shooters and the use of weapons. However, these interesting features automatic KAC PDW, it seems, have not been able to attract potential customers and help to reach the weapons of mass production.
