What do we know about the South Korean company Daewoo? Cars "Matiz" and "Nexia", microwaves, washing machines, well, and ... everything seems. And the fact that this company also produces weapons. Very good small arms - this is somehow not advertised.

It was the army "double barrel" Daewoo K11 and fueled interest in this side of the production company Daewoo.
So, Daewoo K11 - two-caliber small arms under the standard NATO cartridge 5.56x45 mm and 20 mm army grenade air blast. Separate optical sights for shooting a bullet or a grenade. "On-board computer" for accurate aiming with a grenade.
Daewoo K11 - Adopted by the South Korean Army.

The first samples of the complex were ready at the end of 2006, army tests were successfully completed at the end of 2008, and at the beginning of 2009 K11 was presented to the general public at DSEI.
For the first time, work on the new XK11 bicalyber system, which was a direct analogue of the American XM-29 OICW system, was announced in 2006, and in early 2009, a pre-production version of the rifle, the K11 grenade launcher, was already shown at DSEI. delivery of the new system to the army of the Republic of Korea in 2010.
The fact that the Koreans, apparently, have more succeeded in developing a new, promising system than the creators of its concept - the Americans (remember, all the work on the XM-29 OICW system in the United States has been curtailed) is not surprising.

South Korea is one of the world leaders in the development and production of microelectronic products, has a developed military industry, and a rather aggressively-minded neighbor who stimulates the maintenance of high combat readiness and equipment of its troops.
It is assumed that the K11 system will become a means of direct support for infantry at the branch level, ensuring the defeat of soldiers and unarmored enemy vehicles at ranges up to 500-600 meters using 20mm high-explosive grenades with programmable air disruption (above or at the target), and at 250-300 meters - the usual 5.56mm cartridges.

The combined assault rifle - a K11 grenade launcher consists of three basic units - a 5.56mm assault rifle, a grenade launcher with a magazine supply of 20mm caliber and an electron-optical aiming block.
The grenade launcher and machine gun are made in the form of a single assembly and have a common pistol grip for fire control, a single trigger, and a common fuse switch for fire modes. The machine is made according to the classical scheme, with vapor-automatic and locking by turning the shutter. The trigger mechanism allows firing single shots and bursts with a cut-off of 3 shots. Power is supplied from detachable box stores of the NATO standard (from an M16 rifle).

The grenade launcher is made in the bullpup layout, and has a mechanism with manual reloading using a longitudinally sliding rotary bolt.
Food grenades are carried out from detachable plastic shops with a capacity of 5 grenades. The body of the grenade launcher is made of aluminum alloy, the barrel is made of titanium alloy. The design of a grenade launcher provides a programming module for remote detonators of grenades to explode in the air at the target. For the grenade launcher, two types of grenades are supposed so far - fragmentation K167 HE with remote blasting and training K168 TP with inert equipment.

The sighting system includes daytime optical and night infrared channels with a common eyepiece and electronic aiming mark,field of sight with the help of an integral ballistic computer based on the results of measuring the distance to a target with a laser rangefinder integrated into the sight. In addition, the sighting complex includes pressure and temperature sensors (necessary for correct ballistic calculations) and a high-capacity battery that ensures the long-term functioning of the sighting system and the grenade fuze programming device.

And why is all this necessary?
But why? During large-scale military operations of the Second World War, the effective tactics of urban combat were determined — the firing point was struck by a grenade, then the survivors sought from small arms. The under-barrel grenade launcher is currently the standard body kit of any army assault rifle. However, in order to accurately get a grenade to the desired point, you just need to be an ace!
The flight path of a heavy grenade is more complex than the flat trajectory of a rifle bullet.
Therefore, modern grenades for grenade launchers make for the so-called "air explosion", a grenade still on the way up to the target explodes in the air.
However, the damage radius of a modern 20 mm grenade is only 3-7 m, they are used at a distance of up to 300 m, and at such distances it is very difficult to get a grenade even into a circle with a diameter of 3 m. factors and the counting of time for aiming sometimes goes on for a split second, it does not always work correctly.
Another nuance. The length of the barrel of a grenade launcher is always less than the length of the barrel for bullet shooting, and a heavy grenade begins to "fall" much earlier than a light bullet flying at a higher speed. Therefore, for a more flat grenade flight trajectory, it would be desirable to do the opposite: make the length of the grenade launcher barrel longer than for firing a bullet. This increases the effectiveness of hitting targets behind cover at large distances that are inaccessible for a shot from a short-barreled grenade launcher.
Therefore, in the composition of each modern assault unit there is a separate fighter armed with an automatic long-barreled grenade launcher for precise destruction of distant targets. But. In close combat, shooting back from such a grenade launcher is more expensive. Splinters grenades will not spare anyone.
Solve this problem in different ways. The European-American, NATO, approach to this matter was expressed in the creation of a modular design, the XM-29 OICW rifle-grenade complex of the German company Heckler-Koch. The long-barreled automatic grenade launcher “slides” on top of the Heckler-Koch G.36 assault rifle, and not the bottom, like a grenade launcher. Above the grenade launcher - special aiming optics with a rangefinder and a computer for accurate calculation of the flight of a grenade.
The drawbacks of such a bulky design are complete: it is difficult, inconvenient, and accurate shooting with a bullet can be simply forgotten, optics for bullet shooting are combined with “grenade”, but preference is given to shooting with a grenade. However, despite all these shortcomings, leisure-time Americans have calculated that the effectiveness of hitting hidden targets behind an obstacle by an infantryman who is armed with such a “double-barreled gun” will increase by 5 times compared with the M16 rifle / grenade launcher grenade launcher.
But the South Korean gunsmiths solved this problem somewhat differently, in an oriental way wisely and in a South Korean manner technologically. They combined a long-barreled grenade launcher, located above the bullet barrel, in one shooting "combine".Called this "mutant" Daewoo K11.

The bullet assault rifle is made according to the classical scheme: the store is in front, the firing handle is at the rear. But the store for grenades is located behind the pistol grip. And these are not modules, but monolithic, indiscriminate double-barreled two-caliber weapons. The shooting is controlled by a special lever with a single trigger. The optics are separate for the bullet and for the grenade, which allows for very accurate firing, both with the bullet and with the grenade. To reduce the weight of such a "combine", the trunks are made of titanium, the receiver is made of light but durable alloy.

The main characteristics of Daewoo K11:

Maximum effective firing range: 300 m bullet; up to 500 m pomegranate;
Magazine capacity: 30 cartridges caliber 5.56 mm and 5 grenades caliber 20 mm.

For firing grenades, three main types of ammunition are used - a high-explosive fragmentation grenade with programmablea fuse, a cumulative grenade to defeat lightly armored vehicles and a training grenade with a passive warhead.
The electronic fire control unit includes a laser range finder, a wind sensor, a ballistic microprocessor computer for flight trajectory, a day (optical) and night (infrared) mode switch, and a power battery built into the butt.

Shooting complex Daewoo K11 began to supply units of the South Korean army back in 2010
For comprehensive tests, this army “double-barreled gun” was purchased by the Ministry of Defense of the United Arab Emirates, paying approximately 14,000 US dollars for each such rifle. For comparison, the export price of the latest modification of the American M16 assault rifle does not exceed $ 600.
