Reinforced gas spring for MP-512

Among the great variety of wind instruments, the MR-512 pneumatic rifle became very popular. This is due to its moderate price and a number of advantages that allowed this product of Izhevsk Mechanical Plant to take a place of honor among similar imported samples.

Owners can appreciate the quality of this wind weapon, using it for its intended purpose - carrying out entertaining and sporting shooting at long distances. Today it became possible due to the presence of such an element in the design of the rifle, as a gas spring for MP-512.

Alternative to conventional spring

The gas spring for MP-512 is the best alternative to the obsolete standard coil spring. The owners noted that the use of this spring provides a multiple increase in the resource of the weapon. This is explained by the fact that, like all gas springs, the GP-MP-512, unlike standard metal products, even after a long operation, remain unchanged with a stiffness coefficient, as a result of which they are not subject to shrinkage. With this problem, sooner or later, you have to face all the owners of rifles with classic twisted springs.

What is the device?

The pneumatic spring for МР-512 is a device that is a closed cylinder, inside of which a high pressure is formed by means of injected gas. The design of gas springs is non-separable, adjustable. It is mounted in place of a regular twisted spring.

Inside the cylinder there is a rod (plunger), which comes into motion under the influence of gas pressure on the expansion. One end of the cylinder has a welded steel plug. As a lubricant, manufacturers use oil that is poured into the cylinder. The body contains a polyurethane gasket, which is installed in the cylinder after oil is poured.

The gas is pumped through the stem cuff. For downloading, manufacturers of similar products intended for wind guns use nitrogen. This gas is considered the most optimal option for air rifles. This product is purchased already in a refueled condition. The injection procedure is performed by the manufacturers at a temperature of at least twenty degrees. The pump pressure is 120 atm. Special units, available in the design of gas springs, allow owners to independently perform refueling with oil and regulate by bleeding the pressure in the cylinder. Its weight is 100 g, the total weight of GP is 150 g.

Among a large number of manufacturers engaged in the manufacture of gas springs for air rifles, judging by the feedback of users, the special popularity was obtained by Nitro products.

How does GP work?

Under the influence of compressed gas, the plunger located inside the cylinder, moving in the longitudinal direction, creates a force effect on the piston. When a platoon is produced, the rod is pushed into the cylinder, and when fired, it is pushed back. GP injected with gas (80% nitrogen) do not have bullet speed differences during firing, as is often the case in air rifles with conventional coil springs.

Advantages of Nitro pneumatic products

• The gas spring for MR-512 Nitro is widely used in cases when it becomes necessary to increase the power of this air rifle. Such weapons can be used not only for entertaining shooting. 140 meters per second - this is the initial speed, typical for airguns, in which there is a standard twisted spring. For the MP-512, it is possible to increase the initial speed of the bullet to 240 meters per second by applying Nitro products. The power of the rifle makes it possible to use it effectively and as a means for self-defense.
• Gas spring for МР-512 Nitro allows to hold this air rifle for a long time in the cocked state.
• The tactical and technical characteristics of the rifle remain unchanged even when carried in the cocked position.
• Reduces the impact.
• Resource rifle rises fivefold.
• When shooting improves accuracy.

To strengthen the market power, in addition to gas springs, there are classic twisted reinforced, significantly different from the standard springs for wind guns.

Reinforced steel spring "Magnum" for MP-512. TTX

• Spring-piston products.
• The length is 275 mm.
• The diameter of the product is 18 mm.
• It is made of wire 2 mm thick.
• Consists of 34 turns.
• Manufacturer - "Izhmash".
• Country Russia.
• It is recommended to replace the worn out spring with the cuff.

Intensified spring "Magnum" for МР-512, МР-514, ИЖ-22, ИЖ-38, ПРС and ПРСМ is intended.

What is different from a regular analog?

An alternative to standard springs, as well as modern products working on nitrogen, is a steel double spring for MP-512, reinforced with an internal insert (additional spring). The presence of an additional spring in the design positively affects the power of the gun - it increases by 25%. From twenty meters the lead caliber 4.5 mm caliber is able to pierce a centimeter sheet of plywood, which is impossible with the use of a standard twisted spring.

The standard spring provides a speed of flight of the pellet 140-150 m / s. 185 m / s - this rate reaches a double spring equipped with a soft and elastic polyurethane cuff for MP-512.

Characteristics

• The length of the main spring is 245 mm.
• The diameter is -19 mm.
• The turns are made of wire 3 mm thick.
• Number of turns in the outer spring - 34.
• The length of the additional spring (insert) is 250 mm.
• The diameter of the insert is 12 mm.
• The wire thickness is 1.6 mm.
• The number of turns is 54. Of these, 10 are end plates.
• In the production of cuffs, plastic, capron and polyurethane are used.

In the manufacture of a reinforced double spring for insertion, reverse-winding technology is used. This will prevent during the compression possible snack coils.

Springs are sold as a set (basic and optional) or separately. You can buy this product by ordering online.

How to properly operate the gas springs?

• After eight thousand shots, the gun needs to be replaced by oil and pumping pressure. This can be done for maintenance - (maintenance), after which an estimate will be given of the degree of deterioration of the pneumatic weapon.
• A rifle should be included in the inspection if there is an oil leak in it.
• The stem and cylinder of the gas springs should be protected against mechanical damage.
• All GPs are very dependent on the temperature regime. It is undesirable to use them at high temperatures, since hot air increases the pressure inside the cylinder, hence the power of the weapon also rises. This can be bad for the hitfulness of hits. At subzero temperatures in excess of 5 degrees, the gasket seals in the gas spring lose their tightness. This entails venting the gas in the cylinder. In the extreme situations described above, experienced owners and fans of pneumatic weapons recommend not using the GPU, and for a while replace them with conventional wire.

Gas springs are not susceptible to shrinkage, they have a long service life. The guarantee of the continuous smooth operation of the GP is the strict adherence of the owners to the instructions and recommendations of specialists for their application.
