Type 95 automatic rifle was put forward in 1989, and was designed and finalized in 1995. It was named QBZ95 5.8mm caliber automatic rifle (hereinafter referred to as Type 95 automatic rifle, Q light weapon, B rifle, Z automatic, designed and finalized in 1995-95). This gun first appeared in 1997, and it is the weapon of PLA troops stationed in Hong Kong. The troops have been equipped one after another. Become a new generation of automatic rifles in China. It is the first type 95 automatic rifle of China People's Liberation Army and Armed Police Force.

Small caliber automatic rifles for large-scale troops. Type 95 automatic rifle is a rifle with no supporting structure and air-guided automatic mode. The automatic machine adopts short-stroke air guide piston, and the nose is locked by rotation, which can be used for single and continuous shooting. It has 30 rounds of plastic magazines for ammunition. The mechanical sight is a keyhole door. Equipped with muzzle device to reduce noise and flame. Engineering plastics are widely used as external materials. 5.8 mm bullet has small recoil, stable dynamic characteristics of the whole gun, reasonable overall layout, small gun shock when shooting, and high single shot and point ejaculation. The mechanism is reliable. Type 95 automatic rifle can be attached with 35 mm caliber Grenade launcher, which can be quickly disassembled; Equipped with a white sight and a low-light sight, the low-light sight can accurately aim at realistic targets within 200 meters under the condition of low light at night. Equipped with multifunctional bayonet for quick loading and unloading. 95 automatic rifle

Type 95 automatic rifle and QBB95 5.8mm class machine gun (referred to as Type 95 class machine gun) form Type 95 gun family. Later, QBZ95B short barrel short assault rifle was added. These three weapons are generally referred to as Type 95 gun family. QBZ97 automatic rifle is the export type of QBZ95 automatic rifle, and its caliber is West 95 automatic rifle.

The national standard of 5.56 mm is mainly used to launch rifles with SS 109 specifications. The development index requires that the total weight of automatic rifle is less than 3.5kg, and the total weight of machine gun is less than 4.4kg. After the initial design, it is difficult to achieve the index by keeping the high parts common. From the system point of view, it is necessary to increase the gravity reduction, and choose to design the basic gun rifle as the optimization core, and control it at 3.2kg, and the machine gun at 4kg accordingly, so as to get the index of the whole system and each product in the system and maintain the advanced level. The index requires that the total gun length of automatic rifles should not exceed 760mm (barrel length 440mm) and machine guns should not exceed 840mm (barrel length 520mm). After the initial design, under the condition of keeping the universality of parts, the index of machine gun is the most tense. Therefore, the shift machine gun is selected as the optimization core in the whole gun length, and the optimization index is set at 840 mm The whole gun length is closely related to the length of the gun barrel, which directly affects the power level of the product. Therefore, when optimizing the total length of the gun, the selected barrel length must be taken as the boundary condition. When the total gun length of the system reaches the standard, it is difficult to make the power performance advanced. The automatic parts in the 95 gun family are completely universal, and the proportion of common parts between rifles and squad machine guns is high, which is very beneficial to production and maintenance. Steel parts are treated with chemical composite film-forming black phosphating, aluminum alloy parts are treated with hard anodic oxidation, and upper and lower hand guards and upper shell are treated with engineering plastics. When Type 95 gun family passed the reliability test of national shooting range, the failure rate of automatic rifle was between 0.4 and 0.6 ‰, and that of squad machine gun was about 0. 1‰.

Edit the structural features of this paragraph.

It consists of a gas regulator, a piston and a piston spring. The gas regulator is used to adjust the size of gunpowder gas, and the numbers marked with "0", "1" and "2" respectively indicate the positions of gas closure, small holes and large holes. The general setting is "1", and it is set to "2" when the weapon is too dirty to wipe or shoot in cold conditions. When firing a Grenade, it must be turned to the "0" position to prevent the moving parts in the gun from being damaged. The piston is used to bear the pressure of gunpowder gas and push the bolt backwards. The piston spring is used to return the piston to its original position. Exploded view of type 95 rifle

bolt

It is composed of a machine body and a machine head, and is used for feeding, locking, firing and shelling, and can make the hammer enter the ready-to-go state backwards. The machine body is provided with a round hole and a bamboo shoot guide groove for accommodating the machine head and guiding the machine head to rotate, lock and unlock, and the machine body is also provided with protruding bamboo shoots, a machine handle and a return spring seat. The needle is used to hit the primer of the bullet; Shell-pulling hooks are used to grab shell casings (or bullets) from the bore, as well as guide bamboo shoots, protruding bamboo shoots for delivering bullets, protruding bamboo shoots for opening and closing, guide grooves and bullet pits. The machine head has three locking bamboo shoots, and the connection between the machine head and the gun rack is completed by a cylinder, and there is a conjoined opening and closing driving protrusion on the cylinder that can move back and forth. The opening and closing action surface is designed at the top of the protrusion, and the recoil driving surface is designed at the root of the protrusion.

recoil spring

Its function is to store part of recoil energy of bolt and bolt holder, so as to give bolt and bolt holder the necessary energy to advance and complete the safety of pushing, grasping, locking and releasing.

trigger mechanism

Comprise a trigger, a trig pull rod, a stop iron, a firing stop iron, a single-shot stop iron, an out-of-position safety device, a release lever, a reducer, a hammer head, a ham spring, a hammer spring guide rod, a plug and a firing machine seat. Used to control equipment, control shooting and insurance. "0", "1" and "2" on the reducer are safe, single engine and continuous engine positions respectively.

Box receiver

Used to fix bolts, speed reducer and magazine. The outer side of the magazine is provided with a magazine clamping bamboo shoot and a magazine combination opening for combining magazines or drums; There is a locking groove in the shell to ensure the locking of the gun barrel; Pull out a bullet and stick out a bamboo shoot just to pull out a shell (or bullet). 95 automatic rifle

buttstock

It is used to ensure that there is no dust inside the shell and it is easy to operate. There is a cannonball (or bullet) throwing port on the right side of the stock, and there is a double buffering mechanism in the stock consisting of a lever buffer and a rear variable stiffness support plate, which can reduce the impact of the moving parts when they recoil.

Magazine feed

Type 95 automatic rifle generally uses magazine to load ammunition, and can also use drum to load ammunition when necessary. Short shot (2 ~ 5 rounds), long shot (6 ~ 10 rounds) and single shot can be implemented. The rate-of-fire part fires 40 rounds per minute 100. The barrel life is 10000 rounds. Type 95 automatic rifle is equipped with 5 magazines per gun. The magazine consists of a magazine body, a magazine support plate, a magazine support plate spring, a splint and a magazine cover, and is used for containing and supporting bullets. There are three observation holes at the rear end of the magazine body, which are aimed at the bottom of 10, 20 and 30 rounds respectively, so as to observe the remaining amount of bullets.

attachment

Used for disassembly and assembly, wiping and oiling, handling and troubleshooting. Accessories include club head, rod connecting rod (7 pieces), spear, spear rod, sight wrench, oil brush, oil pot, shoulder strap and magazine bag. When in use, the through rod connecting rod and the through rod head or the oil brush are screwed together, so that the internal organs of the barrel can be removed and oiled; Chisels are used to take out pins, shell-pulling hook shafts, etc. The sight wrench is used to adjust the height of the sight when calibrating the gun; Chisels are used to remove the powder residue from the air holes in the barrel.

After pulling the trigger

The trigger pull rod pulls down the firing resistance iron, the hammer moves forward to strike the needle, and the needle hits the bottom fire of the bullet, igniting the propellant, generating gunpowder gas, and pushing the bullet to move forward along the rifling; When the warhead passes through the air guide hole, part of gunpowder gas flows into the air guide hoop through the air guide hole, impacting the piston, pushing the bolt backward, compressing the recoil spring, unlocking the shell, and making the hammer enter the preparation state backward; When the bolt moves backward to the last side, the bolt moves forward due to the extension of the recoil spring, pushing the next bullet into the gun chamber and locking it. At this time, if the reducer is set in the continuous firing position and the trigger is not released, the firing resistance iron cannot stop the hammer, and the hammer strikes the needle again to form continuous firing; If the reducer is set in the single-shot position, the hammer is stuck by the single-shot iron and cannot move forward. If you want to launch again, you must release the trigger and then buckle it. If the reducer is set in a safe position, the shaft of the reducer is stuck, and the soldering iron is ignited to make it unable to rotate and become a safe state; When the hammer is in the rear (that is, in the ready-to-go state), the trigger cannot be pulled and the hammer cannot be fired; When the hammer is in the front (i.e. in the firing state), the moving parts cannot press the hammer backwards to get ready. The aiming device of Type 95 gun family includes traditional mechanical aiming device, simple night aiming device, low-light aiming device with white light aiming device and second-generation low-light tube. There is a pinhole photo door on the scale, which is marked with the words 1, 3, and 5, indicating 100m, 300m, and 500m respectively. It is simple to scale the fluorescent spots on the photo door and the fluorescent spots on both sides of the scope. The sight consists of a sight base, a sight connecting base, a sight fixer and a sight. The sight can be screwed up and down, and the connecting seat of the sight can move left and right. Scribe lines are respectively engraved on the sight connecting seat and the sight connecting seat to check whether the position of the sight is correct. The sight base is used to install white light and low light sight. The magnification of the white-light sight is 3 times, which is used for accurate aiming of long-distance targets. The white-light sight is used for aiming shooting and battlefield observation of targets within 600 meters (when equipped with automatic rifles) or within 800 meters (when equipped with machine guns). When the target width is 0.5m, the target distance can be roughly measured. The white light sight is mainly composed of objective lens group. Indexing adjustment mechanism. Eyepiece group. Eye mask, lighting mechanism and locking mechanism matched with the gun. The magnification of LLL sight is also 3 times, which can accurately aim at vivid targets within 200 meters under the condition of low light at night. Two sights are often used in automatic rifles and squad machine guns, which can be quickly loaded and unloaded on the gun body. The LLL sight is a portable passive aiming device at night, which can aim effectively and accurately at night. Observe and find the location of infrared light sources or other light sources used by the enemy. Under the conditions of moonless starry sky, medium contrast and opaque background, people standing at 200m can be identified. LLL sight is mainly composed of mirror body, imaging system, reticle adjusting mechanism, low-temperature external battery and cover. Bayonets (daggers) are used to assassinate enemies, and can also be used as fighting daggers and field tools. Multifunctional bayonet QBZ95 with bayonet

Consists of a bayonet and a scabbard, wherein the bayonet is provided with a scissors part, a scissors shaft hole, a filing part, a knife ring, a handle seat, a cutting part and a saw part; The scabbard is provided with a sling, a buckle, a millstone, a flat screwdriver, a scissors seat and a shaft. (Note: If you need to stab the enemy with a bayonet in battle, the bayonet should be mounted on the gun. The key points are: put the knife ring in the front end of the muzzle device of the gun, align the T-shaped groove of the handle seat with the T-shaped protruding bamboo shoot of the bayonet seat on the gun, and pull it back to position. When pulling the bayonet, hold the protective sleeve with your left hand, hold the bamboo shoots protruding from the left and right sides of the handle with your right hand (there is a straight line), then pull the bayonet out towards the muzzle, put it in the scabbard and hang it on your belt). Multi-purpose bayonet integrates the functions of cutting, shearing, filing, bottle opening and sharpening. It can be used for both automatic rifles and squad machine guns. Type 95 gun family can fire a series of 5.8mm ordinary bullets and a series of 5.8mm machine bullets when necessary. Step, the machine gun can also fire live ammunition with standard interface size (Ф 22x125mm), and it can also install a quick disassembly 35mm caliber Grenade launcher. Type 95 automatic rifle has fast firing speed, great power and long range. Its performance has far exceeded that of 8 1 automatic rifle. disadvantage?

The tactical performance of Type 95 artillery group is better than that of the Chinese Army in the past, but in the use of the Army, some Type 95 automatic rifles of Type 95 artillery group have also been put forward.

For example, due to the limitation of understanding and technical level, the simplest connector is adopted to expand the function. Although the structure of this method is simple, it can't form a modular function and can't meet the demand of diversified functions of the army. The 95-type automatic rifle is not empty, which is also one of the focuses of the gun dispute. Generally speaking, hanging empty warehouses has two main functions, one is to remind soldiers that the bullets have been finished, and the other is to load them conveniently and quickly. From the point of view of actual combat, whether it is an automatic rifle or a semi-automatic rifle, it has certain practical value to hang an empty position. However, the 95-type automatic rifle that was finally equipped with troops did not hang empty, and many decisive factors are worth pondering. The simple night vision device is filled and assembled with radioisotope 147, which has some problems such as insufficient brightness and easy to fall off, and the half-life of 147 can not meet the requirements of long-term storage of military products, which brings many inconveniences to the use of troops. The second-generation low-light-level sight developed cannot be fully equipped because of the price problem, and the night vision distance of 200m is also insufficient, so the all-weather combat capability needs to be improved. The inconvenient aiming of optical sight is a problem reflected by the army, which is mainly caused by the limitation of "taking mechanical sight as the main aiming mode" of Type 95 automatic rifle. After installing the optical sight, the aiming baseline is too high and the aiming is uncomfortable. The support rifle similar to M 16 usually uses the magazine as the grip part of the lower hanging Grenade launcher. Because of the unsupported structure, the Type 95 automatic rifle can only use the small grip as the holding part after adding the anti-riot Grenade launcher, which is not convenient for practical use. Type 95 gun family adopts the structure without support, which makes the layout of the whole gun very compact. However, when shooting, the shooter's cheek is close to the smoke source, and the incompletely burned gunpowder gas overflows from the shell throwing window, the pistol handle slot and the upper cover cooling slot, which directly stimulates the shooter's eyes or spreads on the aiming baseline, affecting the shooter's continuous aiming shooting. This situation also brings inconvenience to the use of weapons. The double-base flat ball powder used in 5.8mm ordinary ammunition burns incompletely. After firing 2000 rounds (the number of bullets that need to be cleaned in the whole gun), it is usually difficult to take out the gas regulator and piston. Moreover, after more projectiles, the air guide holes will become smaller because of the accumulation of powder and slag. In addition, in order to obtain good external ballistic performance, the 5.8mm ordinary projectile transferred some difficult problems to the internal ballistic, which led to the high muzzle pressure and brought many difficulties to solve the muzzle noise and flame problems. Conventional mercury mine primer is used for 5.8mm ordinary ammunition, which has the problem of primer corrosion for long-term storage, leaving hidden dangers for reliable use. Plastic parts are easy to grind white, mainly because of the plastic material itself. In order to meet the requirements of reliable use at low temperature -45℃, the glass fiber content in plastics should not be too high, and the whitening problem is mainly due to the insufficient strength of plastics, which is difficult to solve. Whitening of plastic parts affects the beauty of type 95 gun family. Type 95 gun family Type 95 automatic rifle

When assembling and disassembling, sometimes there are problems such as missing parts, flip-chip and wrong assembly of parts, which brings inconvenience to the normal use of weapons. Many of the above problems were raised at the beginning of the military test. The Type 95 artillery family has been improving, and some problems may have been solved now. From the published picture analysis, it has gone through at least three stages. The distinguishing features of these three stages can be identified from the shape of the handle of the wire drawing machine and the number of cooling holes in the upper protective wood. Anyway, this gun made China's rifle take a big step forward. As far as China's current production level and comprehensive national strength are concerned, it is still too early to equip weapons with the same advanced technology as American M4 and FN companies. Although there are many controversies, it is the best scheme among more than 80 schemes. Whether there is room for improvement in this kind of gun in the future remains to be seen.
