Recently, the QJZ171 "mountain machine gun " appeared in the exercises and training of the Chinese Marine Corps and was welcomed by the majority of officers and soldiers. The gun is said to have been circulated on the Internet, calling it a "mountain large-caliber heavy machine gun." Although the caliber is still 12.7 mm, its weight, accuracy, information technology and life span have all been greatly improved. Because of the use of titanium alloy materials, it has reduced its weight by 9.5 kg, making it the world's lightest and heavy machine gun. Because the troops have high plateau and mountain combat requirements, it is required to be easy to carry when maneuvering in the mountains. Therefore, the first requirement for the QJZ171 type light machine gun is that it is lighter than the 89 type and can be carried and operated individually.
Although the fuselage of the Type 89 heavy machine gun in my country is only 17.5 kg, the total weight with the bipod is 26.5 kg. Therefore, the new large-caliber machine gun must be light enough to maneuver in the mountains and reduce the number of operators. As a result, this gun has lost another 9.5 kilograms, making it the lightest heavy machine gun in the world! The newly developed mountain heavy machine gun is 9.5 kilograms lighter than the Type 89, and weighs only 17 kilograms, which is 20 kilograms lower than the standard of our army. In addition, the gun has its own bipod, allowing soldiers to operate after reducing the weight of the sight, ammunition and ammunition box.
has data showing that many parts of the gun body, such as the bolt, the frame, the receiver, the butt, and the floating seat are all made of titanium alloy, which can ensure the firepower under the premise of greatly reducing the weight. In addition, the machine gun tripod is made of high-strength carbon fiber composite material with high strength. The entire gun mount weighs about 6 kg, which is nearly 30% lighter than the steel tripod of the 8.5 kg Type 89 machine gun. Fortunately, not only the weight of the machine gun itself is reduced, but the accessories and bullets are also reduced. The total weight of the whole system does not exceed 40 kg.
QJZ171 improves the shooting accuracy; the shooting distance of the machine gun is within 200 meters, and the natural dispersion does not exceed 10 cm. When the gunner fired with a bipod light machine gun at a distance of 200 meters, the scattering radius was less than 32 cm. When using a tripod as a heavy machine gun, the dispersion radius does not exceed 24 cm. When the distance is 1000 meters, 70% of the projectiles will spread no more than 2.2 meters. I don't know how much higher than 89. At the same time, the degree of informatization of guns is constantly improving. The gun is a continuation of the Type 89 heavy machine gun, equipped with a new white light sight and infrared sight to improve accuracy and range. This new type of large-caliber machine gun
makes full use of new technologies and methods, and the barrel life is much longer than that of previous large-caliber machine guns. It is reported that the machine is made of new ultra-high-strength, heat-resistant, and wear-resistant materials, and a large number of barrel precision forging processes are used. The service life is 1.5-2 times that of the 89 heavy machine gun. In this way, even if the total price of firearms increases, but the service life increases, the cost does not increase much, which is acceptable to the military.
In general, the new 12.7 mm heavy machine gun is light in weight and has good maneuverability, making it very suitable for combat in plateau and mountainous areas. Because the Qinghai-Tibet Plateau is sparsely populated and the environment is harsh, there are often no roads, only human transportation, and sometimes fighting by itself, so it is necessary to have a machine gun that can be carried and operated by individual soldiers.
