It all started in one place. For example, all animals, regardless of size, shape and species, must attribute the parent-child relationship to the same origin. Similarly, most modern combat rifles in the world can basically be attributed to four origins. Of course, there may be other small origins, but these four are more lasting.
Light weapon is a special mechanical system, which develops with the development of industry and military. At first, someone may have an idea that looks very effective, but after that, the idea will be constantly adjusted and improved over time until it becomes better, more reliable and more effective. But in fact, if you want to study modern light weapons, you can sort out the origins of various light weapons through research.
H & ampk Company: Combat Power Representative
The roller locking mechanism of HK33 is the least common mechanism, which comes from STG45 prototype gun. In addition, the roller locking mechanism later appeared in quite a few rifles and submachine guns of HK Company, and its original concept came from MG42 machine gun which provided chain bullets.
MG42 machine gun is considered as the best machine gun in World War II. The gun is made of steel by stamping, with fast production speed, low cost and extremely fast firing rate. It is indeed a powerful fighting tool, and its core lies in the novel roller locking mechanism.
Like other products produced by HK company, the sight is very complicated, but it is very effective. Both HK rifles and submachine guns with closed rollers adopt stamped steel nail bins, which can be produced in large quantities very economically.
The basic structure of the roller locking mechanism is composed of a pair of rollers, which can be stuck in the roller groove at the rear end of the gun bore. After the barrel is fired, the roller can delay the movement of the barrel and move backwards when the pressure in the barrel drops to a safe level.
The rolling lock mechanism is a semi-free gun automatic mode, which is different from the pneumatic automatic mode, so the weapon using this mechanism has lower requirements on the barrel length. HK33 firearms are not designed with empty bin hook function. Although it is very painful, it can also get very cool operations, such as knocking down the steering wheel after replacing a new magazine.
STG45 assault rifle is an experimental 7.9233mm caliber rifle, which was developed by Mao Se Arsenal for the German Defence Force at the end of World War II. This design was brought to Spain, and the CETME combat rifle was developed after the war. German engineers designed and developed G3 rifle, HK33 rifle, MP5 submachine gun and other series of firearms by using the principle of this mechanism.
There is a slot in the front of the HK frame repeater, which can be used as a line trimmer. When the wire is used, put it into the groove to hold it down. As long as a bullet is fired, the wire can be cut under the impact of the bullet, which can be applied to communication lines and obstacle lines of various sizes.
Although rolling lock guns such as G3 rifle still exist in the war zone where funds are scarce, and some countries are also producing such guns, on the whole, the rolling lock mechanism has been replaced by simpler things. Although somewhat outdated, the HK33 rifle is still an effective fighting weapon.
AK rifle: Kalashnikov meat grinder
AK74 rifle is an upgraded version of AK47 assault rifle after World War II. Firing 5.4539mm small caliber bullets is a Russian standard infantry weapons. Kalashnikov participated in the Battle of Teske, Brignet, as a member of T34 tank convoy in World War II, and fought against the Germans.
After the injury, I taught myself the knowledge of light weapons design in the hospital and sent it to a special weapons school to learn how to design AK47 rifles. Many people don't like the huge shorthand machine of AK74 rifle. It is difficult to operate, it is difficult to operate quietly, but it is still very effective.
The adjustable shutter of AK74 rifles looks old, and not all the handles of AK74 rifles can be easily operated. On the left side of the shell of AK74 rifle, there is a guide for installing optical sight. The long ball brake of AK74 rifle is conspicuous, but it is very effective.
AK rifle adopts long-stroke piston-induced design, the reciprocating gun parts are heavy, and the heavy gun rack has great energy to complete automatic action. If the rest compete with one or more assault rifles, the AK rifle will always be the last broken gun. Although the gun produced by this concept is not the most accurate, it can shoot stably every time the trigger is pulled.
Kalashnikov assault rifles can be found everywhere in the world. Early versions of AK series rifles fired 7.6239 mm ammunition. As the name implies, AK74 was developed by 1974. It uses a 5.4539 mm bullet and has a very long 53-caliber bullet. This deformation was first put into the war in Afghanistan in 1979, and AK series assault rifles developed into AK 100 series assault rifles.
Godfather of Rifle: Eugene stoner
M 16A 1 is the final version of the AR 15 rifle used by the US military in the Vietnam War. It is light and maneuverable, and its early failures have been solved. 1956, Eugene stoner and other former marines tried to integrate aviation technology into the emerging world of modern light weapons. He designed a new AR 10 rifle.
The shell is made of aviation aluminum and adopts a novel and simple direct wind-induced automatic mode. M 16A 1 The upper and lower boxes of rifles are made of aviation aluminum. The early model of this structure is AR 10 rifle, equipped with 7.625 1mm bullets. It was first used in the rifle test of the US Army in 1956, but the AR- 10 finally lost to the T44 rifle which later became the M 14 rifle.
However, this structure was later miniaturized. The .223 Remington rifle bullet and the .223 Remington rifle bullet were actually designed by Eugene stoner. Through the small caliber design, the 55-grid .223 caliber bullet is accelerated to about 3000 feet per second. It can be said that this kind of ammunition represents a great leap in military and police weapon technology.
The straight air guide structure of M 16 rifle makes the shape of the front end of the guard wood smaller, and at the same time, the closed cage anti-inflammatory brake is used to replace the original three-legged muzzle device, because the previous open type is easy to be damaged.
The miniaturization of the AR- 10 rifle became the AR- 15 rifle, and later became the M 16 rifle, which was adopted by the US Air Force in the early 1960s, and was later taken part in the Vietnam War by soldiers of the Army Special Forces. During the war, there were problems with the new rifle, but they were finally solved. Eventually it became a military rifle with a long service time in American history.
The original M 16A 1 rifle was a very light combat weapon. Since then, various accessories have been installed. M 16/M4 series rifles are very light and easy to operate. Usually 30 detachable magazines are used to supply bullets, which is very accurate. Bullets are still lethal at a distance of 1000 meters, but the direct wind guidance mechanism needs regular maintenance, but there is no doubt that the US military will continue to use this rifle.
Eugene stoner's New Ambition
AR 18 rifle is a new generation of evolution of M 16, which has the advantages of convenient production, cleaner automatic action, lower temperature and more reliable gas piston system, and has produced several other commonly used advanced combat rifles.
1963, Eugene stoner and arthur miller began to study a new generation of substitutes for AR 15 rifles. The patent of AR 15 rifle has expired, so it is time to develop follow-up weapons that are easier to manufacture. The original AR rifle was truly revolutionary,
However, production requires advanced industrial capabilities. Later, stoner left the project, but the project finally developed into a 5.56mm AR 18 rifle, which was put into production in 1969.
The AR 18 rifle adopts a more traditional design, and the silo adopts stamped steel, such as HK33 or AK74 rifle. Semi-skilled workers can mass-produce these parts on industrial-grade presses. The direct blowing mechanism is also changed to the traditional piston guide design. The cover spring of AR 18 is designed at the front of the gas piston, so the stock can be folded.
The production cycle of AR 18 rifle is 1969 to 1985. These rifles are produced in the United States, Britain and Japan, but they are rare in combat operations. Although AR 18 itself is not eye-catching, guns designed with reference to AR 18 rifles continue to dominate the gun market. AR 18 upper and lower cabinets are made of stamped steel, which is easy to produce.
The basic movements of AR 18 rifle were later used for reference by Steyr AUG rifle, HK4 16 rifle and G36 rifle. These rifles still serve in various forms in the world army and law enforcement departments. For example, the AUG rifle is equipped in the Australian Army, and HK4 16 is equipped in the US Special Operations Force.
The United States Marine Corps is equipped with M27 rifle developed by HK4 16, while G36 has been serving in the German Bundeswehr since the end of 1990s. The muzzle device of AR 18 rifle is similar to that of M 16. AR 18 rifle adopts rigid follow-up handle, the cover spring is designed as air guide system, and the stock can be folded.
The piston type is cleaner than the direct blowing type, so the gunpowder gas will not directly enter the filter cartridge, and there will be no problem of temperature rise of the filter cartridge. AR 18 rifle adopts straight gun seat design, which is beneficial to reduce muzzle jump. Will believes that the basic structural origins of modern rifles mainly include the rolling lock mechanism adopted by HK33 rifle, the traditional AK design adopted by AK74, the classic AR design of M 16A 1 and the piston-oriented AR design of AR 18.
