In the1950s, China introduced the AK47 7.62 assault rifle installed in the Soviet Union at that time. Subsequently, there were two improvements to the 56-type 7.62 mm submachine gun: the 56- 1 7.62 mm submachine gun with the butt folded down and the 56-2 7.62 mm submachine gun with the butt folded sideways. The application range of 7.62 mm submachine gun makes it develop in the direction of miniaturization and lightweight. These guns make up the type 56 assault rifle family. Type 56 assault rifle also exports a lot to other third world countries.
Type 56 7.62 mm submachine gun adopts the principle of automatic air guide, which can be used for single and continuous firing. Adopt cylindrical sight, notch door and arc door. The biggest feature of this gun is its fierce firepower and reliable action, which can adapt to special environment and weather conditions. The whole gun is short, easy to carry and operate, simple and compact in structure, and easy to train and maintain.
Due to the long production cycle and limited by the conditions at that time, type 56 assault rifle mainly adopted mechanical aiming, and no functional expansion interface was reserved. So, all kinds of optical sights, laser pens, tactical grips, etc. Unable to install. It cannot achieve long-range accurate shooting, does not have the ability to fight at night, and cannot meet the needs of modern warfare.
In order to meet the needs of modern warfare, domestic manufacturers have expanded, upgraded and improved the functions of the 56- 1 7.62mm submachine gun, and launched the 56- 1G 7.62mm submachine gun. On the premise of not changing the structure and power characteristics of the 56- 1 7.62mm submachine gun, the upper and lower wood guards, gun butts and grips were upgraded and improved.
Improvement of upper and lower hand guards: the upper and lower hand guards of 56- 1 submachine gun are made of wood, and the upper and lower hand guards of 56- 1G submachine gun are made of aluminum alloy. Picatinny rail is arranged on the top of the upper guard wood, the bottom of the lower guard wood and the left and right sides. Accessories such as laser pens and tactical lights can be installed on the left and right guide rails, and accessories such as small grips and bipeds can be installed on the bottom guide rail, which greatly expands the tactical performance of the 56- 1G submachine gun. In addition, the upper and lower hand guards adopt hollow design, which is beneficial to heat dissipation and reduces the quality of the whole gun.
Improvement of gun stock: There are three kinds of gun stock in type 56 assault rifle, among which the 56-type assault rifle adopts wooden fixed gun stock, the 56-/Kloc-0-type submachine gun adopts metal folding gun stock, and the 56-2 submachine gun adopts transverse folding metal gun stock. At present, wooden stock is rarely used in rifles. Although folding metal butt can effectively shorten the length of gun body, the comfort of metal shoulder plate is not good when shooting with shoulder butt. The improved 56- 1G submachine gun butt is made of polymer material, and its length can be adjusted flexibly. Polymer gunstocks improve the comfort of shoulder and cheek shooting. The length can be adjusted to meet the needs of individual users. Docking is the same as AR series and can be selected according to different requirements. Gunstock with different functions.
Improvement of the grip: The improved small grip of the 56- 1G submachine gun is made of polymer materials. The shape design makes it more beautiful and fashionable, and it is more comfortable to hold. From the color point of view, type 56 assault rifle's upper and lower armrests, grips and wooden fixed stock are all dark red, and the holster, barrel and magazine are all black. 56- 1G submachine gun's upper and lower handrails, stock and grip are all black in appearance, which is consistent with the black case, barrel and magazine. The overall tone is cold, which is more in line with the attributes of firearms as weapons.
Type 56 assault rifle's shell cover is relatively thin, so it is impossible to directly install the optical sight on the shell cover. In order to solve the problem of installing optical sight, 56- 1G submachine gun added a set of sight bracket with picatinny rail. Optical sights such as white light, hologram and red dot are installed on the aiming frame, and optical sights, low light level image intensifier and picatinny rail can also be installed in series on the armguard to meet the needs of all-weather operations.
