Reinforced gas spring for MP-512

Among the wide variety of wind weapons, the MP-512 air rifle was especially popular. This is due to its moderate price and several advantages that enabled these products of the Izhevsk Mechanical Plant to take pride of place among similar imported samples.

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

Alternative to conventional spring

The gas spring for the MP-512 is the best alternative to the outdated standard coil spring. The owners noted that the use of this spring provides a multiple increase in the resource of weapons. This is due to the fact that, like all gas springs, the MP on the MP-512, unlike standard metal products, even after long-term operation, remain with the same stiffness coefficient, as a result of which they are not subject to shrinkage. Sooner or later, all owners of rifles with classic twisted standard springs have to deal with this problem.

What is a device like?

The air spring for MP-512 is a device that is a closed cylinder, inside of which high pressure is generated using the injected gas. The design of gas springs is non-separable, adjustable. It is mounted in place of the standard twisted spring.

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

Gas is pumped through the stem cuff. For injection, manufacturers of similar products intended for blowguns use nitrogen. This gas is considered the best option for air rifles. These products are purchased already in the filled state. The injection procedure is carried out by manufacturers at a temperature of at least twenty degrees. The pump pressure is 120 atmospheres. Special components available in the design of gas springs allow owners to independently refuel and regulate by bleeding the pressure in the cylinder. Its weight is 100 g, the total weight of the GP is 150 g.

Among a large number of manufacturers engaged in the manufacture of gas springs for air rifles, judging by user reviews, Nitro products were especially popular.

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 made, the rod is pressed into the cylinder, and when fired, it is pushed back. GP injected with gas (80% nitrogen) do not have bullet velocity drops when firing, as is often the case with air rifles with conventional coil springs.

Benefits of Nitro Pneumatic Products

The gas spring for the MP-512 Nitro is widely used in cases where there is a need 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 characteristic of airguns, in which there is a standard twisted spring. For MP-512, it is possible through the use of Nitro products to increase the initial bullet speed to 240 meters per second. The power of the rifle allows it to be used effectively as a means of self-defense.
The gas spring for the MP-512 Nitro keeps this air rifle cocked for a long time.
The performance characteristics of the gun remain unchanged even when worn in cocked position.
Reduced recoil.
The resource of the rifle is increased five times.
When firing accuracy improves.

To strengthen the power on the market, in addition to gas springs, there are classic twisted reinforced, significantly different from standard springs for air 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 2 mm thick wire.
Consists of 34 turns.
The manufacturer is Izhmash.
Country Russia.
It is recommended to replace a worn spring with the cuff.

The reinforced Magnum spring is intended for MP-512, MP-514, IZH-22, IZH-38, PRS and PRSM.

What is the difference from the standard analogue?

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

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

Characteristics

The length of the main spring is 245 mm.
Diameter -19 mm.
The turns are made of 3 mm thick wire.
The number of turns in the outer spring is 34.
The length of the additional spring (insert) is 250 mm.
Insert diameter - 12 mm.
The thickness of the wire is 1.6 mm.
The number of turns is 54. Of these, 10 pieces are end ones.
In the manufacture of cuffs, plastic, nylon and polyurethane are used.

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