Composition of several large 97 explosion-proof guns

The shotgun is a kind of smooth-bore weapon. The military/police shotgun basically consists of a smooth bore barrel, an automaton, a trigger, a magazine, a aiming device, a stock and a grip. According to the loading methods, most of them belong to semi-automatic shotguns and automatic shotguns, and there are three kinds of ammunition supply methods: pump magazine (tube), wheel magazine and magazine magazine.

Shotgun mainly fires cluster spherical projectiles (shotgun projectiles). The bore of the barrel consists of three parts: bore, sliding bore and throat constriction, which are connected by taper. The gun bore is loaded with a shotgun, and the sliding bore is the accelerated motion section of the shotgun projectile. On the section about 60 mm away from the muzzle, the position where the diameter decreases appropriately along the muzzle direction is called throat constriction. The projectile flies out of the muzzle under the action of cluster, which increases the shooting density and range.

Actually, the shotgun is not mysterious. Besides military/police, there are also civilian shotguns. Civil shotguns are mostly used for hunting (shotguns) and shooting sports (flying saucers and skeets).

The caliber of firearms is generally the diameter of the warhead. For example, QBZ03 automatic rifle fires DBP87 5.8mm ordinary ammunition with a caliber of 5.8 mm, but the caliber of shotgun is different, because the shotgun fires a shotgun, and its "warhead" is a spherical projectile, which is encapsulated in a shell, and the shotgun is not the same. The caliber of the shotgun refers to the diameter of the sliding chamber, which is distinguished by the diameter of the shot made by dividing each pound of pure lead into several parts. For example, the caliber of 12 means the diameter of112 lb of pure shot put (18.5mm). The larger the caliber, the smaller the diameter. This method is used for 1 to 32. Shotguns No.4 to No.00 are also called deer bullets or large lead bullets. Commonly used are 10, 12,16,20 and so on. At present, most military/police shotguns use 12 caliber. According to the international standard, the actual caliber of 12 is18.5 mm.

The 97 18.4mm riot gun is named after China's characteristics, and its bore is 0. 1mm smaller than the most popular shotgun in the world, so it is difficult to determine the caliber by the international standard, which is an innovation. At first, this scholar thought that this series of riot guns could fire 12 shotguns. Later, he read the training program of 97 18.4mm riot gun, and clearly stipulated in the "main elements and performance indicators" that "12# shotgun bullets cannot be fired."

In the picture, the soldiers are holding riot guns driven by 97-2 18.4mm magazine pump. The finalized product published on the manufacturer's website belongs to the folding stock, but the stock of the riot gun in the picture is too short to stick on the cheek. It is suspected that it is a newly developed and finalized telescopic stock riot gun (the stock is retracted).

The gun is supplied by magazine, and the shooting mode is driven by pump (referring to semi-automatic shooting, pulling the front guard by hand, driving the automatic machine to complete automatic actions such as shell extraction and shell throwing). This action is similar to the process of inflating with a pump, also known as pump. )

In fact, everyone has seen riot guns inside and outside banks-as security guards escorting banks, most of them are equipped with 97- 1 model 18.4mm riot guns (folding brackets).

The ammunition supply mode of this gun is tubular magazine. Tubular magazine (also called tubular magazine) is usually installed under the barrel, and the front and rear bullets are loaded one by one. Because the warhead of the latter bullet is connected to the bottom of the shell of the previous bullet, a pointed bullet cannot be used, and a flat or round bullet must be used. Modern tubular magazines are mostly used on shotguns. When transporting bullets, pull back the guard wood, send the last bullet to the ammunition feeder, and the ammunition feeder lifts the bullet; In the process of resetting the wooden guard, the ammunition feeder sends the ammunition into the gun bore. The whole process also completes the actions of bolt retreating, breaking hammer, bolt re-entering and locking. When loading ammunition, the front end of the warhead lifts the ammunition feeder, and the finger pushes the ammunition into the magazine. Ejecting bullets is also very convenient-in the process of pulling back the guard plate, you can eject a bullet by lifting the bullet with your fingers, and then you can eject a bullet every time you press the switch spring.

In combat, it is often necessary to replace different kinds of bombs according to different needs. Tubular magazines are more convenient to change ammunition types than magazines.

Whether it is a shotgun with a tubular magazine or a shotgun with a magazine, the shotgun can be loaded directly from the shell throwing window without a magazine.
