Today, on arms counters, a wide range of various "pneumatics" is presented to the attention of fans of wind weapons. Of all the available types of pneumatic weapons, the spring-piston system has proven itself well. The article contains information on what constitutes a pneumatic pistol with a spring-piston mechanism.
How does a wind weapon work?
Unlike military weapons, air pistols and rifles are fired without burning gunpowder. The bullet is ejected from the barrel channel due to compressed gas or air, which gives the bullet the necessary energy.
How are products classified?
"Pneumatics" can have a different purpose, design, workmanship, and, therefore, different costs. The main criterion by which a wind weapon is classified is the method of initial gas compression. Modern models of "pneumatics" are products equipped with the following mechanisms:
- Pneumatics PCP. Systems with manual or compressor pre-pumping. Pistols are equipped with special containers into which air is pumped with a pump.
- Pneumatics using carbon dioxide. Pistols are equipped with special cylinders that contain CO 2.
- Wind weapons with a spring-piston system. A pneumatic spring piston (PPP) pistol fires using compressed air, which is formed due to the movement of the piston under the influence of an expandable spring. This type, unlike other "pneumatics", has a simple design.
How does the RFP mechanism work?
The design, which is equipped with a pneumatic spring-piston pistol, consists of the following parts:
- Cylinder.
- Springs
- Piston and cuffs.
During the cocking of the piston, the spring is pulled back and locked in the rear position. The piston is cocked using the lever. This function is performed by a breakable trunk. After pulling the trigger, the spring is released and, moving forward, pushes the piston, which, as it moves inside the cylinder, reduces the air gap, thereby creating the pressure necessary for the bullet.
According to the owners, the spring is considered the weak point of such "pneumatics". Improper use and storage of weapons can adversely affect their resources. To avoid this, it is recommended to store "pneumatic" only in a discharged form. To do this, after operating the gun, unclench the cocking spring by firing a blank shot.
If the standard spring or piston cuffs have already fallen into disrepair, this can be fixed by supplying a pneumatic piston spring-piston gas spring. In GP models, the piston is affected by compressed gas. Reduced spring shrinkage, recoil and noise are characteristic features of such "pneumatics". Despite the high cost of gas springs, air guns equipped with a GP have several advantages:
- Shooting is much quieter. This is achieved due to the absence of stresses on each other of the turns of the steel spring.
- The return is reduced.
- Shooting is characterized by constant power. This is due to the fact that the gas spring is not subject to shrinkage during operation.
Product from IZhmash
Among fans of wind weapons, pneumatic pistols spring-piston IZH MP-53M gained great popularity.
Externally, this model is very similar to a rifle with a removed butt and a half-shortened barrel. This weapon has an initial speed of 100 m / s. According to the owners, the manufacturer underestimated the speed a bit: in reality, it is 110 m / s. Also, the characteristics of the aiming range were underestimated. The product data sheet indicates an aiming range of 10 meters, while this “pneumatic” has high accuracy at a distance of 25 meters. The maximum range is 100 m. For shooting, lead bullets of 4.5 mm caliber are used.
The gun has a muzzle energy of 3 J, which allows it to be effective only for training shooting, but not for hunting, since for hunting “pneumatics” 15 J. planes.
Kickback
In the design of "pneumatics" using preliminary pumping, there are no moving massive elements, which cannot be said about spring-piston mechanisms. Judging by the reviews of the owners, the pneumatic spring-piston pistol has a strong recoil. When firing marked twitching arms back.
Diana MP-5 Magnum
This is the most powerful pneumatic spring piston pistol. Unlike the Russian MP-53M and Turkish Hatsanov, this “pneumatic” has a capacity of 7.5 J, which has already been appreciated by many owners.
The gun is cocked by breaking the barrel. The bullet flies out under the influence of air, which is formed as a result of compression of the mainspring in the cylinder. The trigger mechanism is somewhat different from the MR-53M.
In the MP-5 Magnum, a cocked piston extrudes the sear. The lock is triggered. As a result, there is no dependence on the strength of the mainspring. This had a positive effect on low recoil when firing. The descent is characterized by ease, it does not require idling.
Advantages of the RFP
- "Pneumatics" with spring-piston mechanisms are easy to operate.
- They have sufficient power at short distances.
- Low price.
- Noiselessness.
- Caring for "pneumatic" does not require large financial investments from the owner.
disadvantages
- The lack of automation forces the shooter to reload every time after a shot.
- The reload process takes a long time.
- High return. It complicates the use of optical sights.
