Air rifle MP-512 fans wind weapon is considered to be one of the most popular. A worthy competition to this model in the market is only for the pneumatic Makarov pistol.

Initially, the popularity of the rifle Mr-512, among other specimens of the brass arms was caused by the absence of the buyer's choice. On the shelves there were only these pneumatic rifles and Makarov. Eventually, when the Windows of gun shops filled with expensive German and Spanish wind models, on the popular rifle Mr-512 significantly influenced by its relatively low price.

MP 512 with gas spring velocity

“cat”, as the people call this model became one of the most purchased among the rest of the airguns. The cost is several times less, and picking huge spring mechanism significantly improves performance characteristics. Izhevsk mechanical plant successfully produces an air rifle MP-512 with a gas spring, the velocity and power of which are not inferior to foreign Pneumatics.

Rifles "Murka"

Today in the sale is a stronger version of the “cats”. This air rifle MP-512 m caliber 4.5 and 5.5 mm and a capacity of 25 joules. Initially, Mr-512 was presented in two versions – for the production of the bed was used, wood or plastic.

The Model of this rifle first appeared on the shelves of gun stores in 1998.

What is a gas spring & how does it work?

Spring pneumatic is a hollow cylinder inside of which contains a compressed gas. In one part of the plunger is located – a special rod, which moves under the influence of compressed gas in the longitudinal direction. By pushing the plunger out of the cylinder creates a force on the piston Pneumatics. During the platoon is Whtie of the rod into the cylinder, and when fired the gas, which is the force the spring pushes the rod back.

spring - piston pneumatic

According to this principle works MP-512 with a gas spring. The velocity of the bullet (photo below is work features spring-piston airguns) depends on the speed accelerates, the compressed gas plug and piston.

If necessary, you can increase cylinder pressure to 250 atmospheres, which significantly increase the bullet speed (up to 230 meters per second).

Gas spring Premium series

Reinforced springs are used for such Premium air rifles of Russian production, as Mr-514 Mr-512. With gas spring velocity is unchanged. What can be said about wind variants, equipped with conventional coil springs. Such weapons muzzle velocity is unstable, observed it changes from shot to shot.

bullet speed MP 512 with gas spring

Features:

  • Diameter of the stock springs is 0.8 cm;
  • Length gas springs – 119 mm;
  • Stock spring has a length of 88 mm;
  • Runs the force on rod 55 kg;
  • Pressure pumping – 120 atmospheres (depending on the individual preferences can be ordered setup for pressure, to increase it to 250 atmospheres);
  • Used for filling gas-nitrogen 80 %;
  • The body of the spring and its rod are made from steel.

During the operation of the airguns, reinforced gas spring, it is necessary periodically to carry out its technical inspection. It is advisable to do it after eight-ten thousand shots.

Gas springs from Vado

Reinforced springs manufacturer Vado adapted for such Russian air rifles like MP-512 "Murka" and the standard IZH-38.

Features:

  • Spring has a diameter of 0.8 cm;
  • Pressure pumping – 115 atmospheres;
  • On the stock is running pressure 53 kg;
  • Used for filling nitrogen 80 %;
  • In the production of spring steel is used.

This spring is sold individually. It is attached to a hard-centering washer. Once a year or after ten thousand shots air rifle must be handed over at check in.

Features and Advantages of the shooting of the MP-512 with gas spring

  • Bullet Speed increases significantly (up to 2 m/s). There was an increase in capacity to 15 %.
  • Increased accuracy of hits. The sound of the shot is very short and scathing.
  • Reinforced gas spring for Mr-512 easily mounted on the Pneumatics standard, without requiring changes to its construction, turning or milling to its refinement. At the same time, using hard-centering washer thru the spring you need only to center the heel. Washer provided in the kit. The ease and simplicity of installation of reinforced springs are characteristic only for the rifles in 2008. The products are released before this time, the installation of the gas spring is done with the mandatory modifications in the structure. The owner is required to pierce the heel with a diameter of 20 mm to 32 andto Refine mechanisms for the platoon and descent. New models and a standard air rifle IZH-38 with installed reinforced spring once a year should be given to the center of technical inspection for verification.
  • Comfort when shooting. Velocity MP-512 with gas spring increases due to the elimination of vibrations and side oscillations, which is typical in the operation wound spring in a standard air rifles.
  • Uniform platoon, requiring the minimum of effort.
  • Due to the spring increases the efficiency of Mr-512.
  • The Ability to store a cocked weapon without negative consequences for the quality of the shots. No change of characteristics takes place at the MP-512 with a gas spring. Speed of bullet (up to 2 meters per second) is characterized by a stability that is highly valued by hunters. The opportunity to leave the rifle with the gas spring when it is cocked due to its low load on the details of USM. Coil springs to put in the cocked position is not recommended – will lead to reduction of service life of details of USM.
  • Soft down.
  • Unlike the air rifles with coil springs, brass products, features of their gas counterparts, there are no extraneous clanking sounds in the system when firing and platoon. This feature provides for Mr-512 gas spring, which develops a speed of two meters per second.
  • The Operational lifetime of the gas spring 5 times more than twisted.
  • Equip wind weapons gas springs enables the owner to use rifle scopes. This is due to the low recoil while firing.

What you need to remember the owners of the MP-512 with a gas spring?

Air rifles with reinforced spring, in addition to increasing the bullet velocity, power, increase comfort during shooting and other positive qualities, there are two drawbacks caused by the characteristics of the gas springs:

  • SE depends on the temperature. This is due to the quality of the presence of gas used. In sub-zero temperatures, a decrease in pressure in the cylinder, which adversely affects the power of weapons (crashes 5 %). Owners of rifles MP-512 with a gas spring it is not recommended to shoot in the cold, because in such conditions the metals used in weapons, become very fragile, and the lubricant is viscous. Thus all seals of rubber and polyurethane lose flexibility, harden.

Mr 512 of the gas spring speed

  • Gas springs are complex mechanical product, which is sensitive to different contaminants, and mechanical hazards. This spring is more likely to be broken than twisted. Therefore, in the absence of the right skills to perform its installation is not recommended. Better this work to professionals.

Gas springs are used in air rifles since the late 80-ies. The development of technology allows to improve wind weapon. The market is constantly updated with new products of manufacturers that supply a variety of models of spring-piston airguns.
