Chapter 516： Big surprise for the sister (below)

Forget it, the car first like this, a commuter car, it is estimated that the sister is more concerned about sniper rifles.

The domestic sniper rifle is actually lacking in truth. At first, it was only with the Mosinnagan sniper rifle. Later, the SVD of the old Maozi, which was copied, became the 79-type sniper rifle and the modified 85 in the 1979. Both of these are essentially SVD imitations, but differ slightly in the production process and some subtleties.

The 85th type began to equip the troops in 1987. In the following ten years, the gun was heavily equipped with our army and the domestic armed police and public security special police units, and exported.

Since the Soviet Union was a socialist country at that time and did not recognize intellectual property rights (China was the only socialist country with patent law at the time), it did not pursue such a direct imitation of the Soviet Union.

Although the 79/85 type has the advantages of long range and great power, it also has the disadvantages of large recoil, high noise, less bombs and poor maneuverability. In particular, the full gun length of more than 1200 mm is not suitable for the street fighting environment, as well as access to work and vehicles, and it is not convenient to cover the scene when incidents are hidden. On the other hand, the weight of the whole gun is too large to increase the individual load, and it is inconvenient to carry it over long distances, and it is not suitable for mountain and jungle operations.

Then there is the 88 style, which is familiar to everyone and is in active service. But everything is not perfect. Although the 88-type sniper rifle has excellent overall performance, it also exposes some shortcomings in the use of the troops and needs further improvement. Corresponding to the Type 88 is the Type 97 sniper rifle, which is a Type 88 foreign trade type that launches a 5.56mm NATO bullet.

The JQ 12.7mm large-caliber sniper rifle only solves the problem of presence or absence, and does not catch up with foreign products in terms of range accuracy and versatility.

Therefore, the current situation in China is that there are 88 styles for small caliber, 85 styles for medium caliber and 00 style (L115A3) for Guo Tailai later, and JQ for large diameter. Among them, only 00 can be called the world. The advanced level, the other basically solves the problem of whether there is a problem, and has not yet solved the problem of good or bad.

The teacher and sister are more concerned about it, and it is normal. The problem of historical debts is not something that can be caught overnight, but the sisters really want to catch up. Without advanced ammunition, even if you use NATO's already-tested ammunition. At this point, Guo Tailai's 00 is a typical example. It uses the internationally popular .338 Lapu Amagnan special sniper ammunition. In fact, many high-performance sniper rifles in the future use this 8.6mm sniper. bomb.

There are many requirements for the design of firearms in China, and the versatility must be good. The tests in various complicated environments are particularly strict. Many world famous guns have failed to pass the strict Yellow River sediment test in China, such as the famous rifle-free stalwart Styrian AUG. Before the test, everything was fine, that is, the Yellow River sediment test could not be passed, and it was regrettable to give up.

However, the versatility of various environmental tolerances is achieved at the expense of precision, so it is unlikely that these standards will be applied to high-precision sniper rifles. Also need high precision, but also to be resistant? Whose high-precision sniper rifle is okay in the water to soak into the sand and still use the jeep to crush it? After this play, the shooting accuracy of the barrel can be guaranteed? Or is the installation accuracy of the sniper mirror still in line with the shooting requirements of one kilometer?

Therefore, Guo Tailai considers more high precision, low weight, good balance, short size for easy carrying, good man-machine performance, and then naturally chooses the unsupported structure, consistent with the original intention of the 95 type, and also domestic The current weapons and equipment design ideas are similar.

After pondering, Guo Tailai finally chose the US Desert Tactical Arms (DTA) unsupported structure to rotate the pull-type sniper rifle SRS, the SRS sniper rifle is called "StealthReconScout" (StealthReconScout). The structure is simpler, lighter in weight, and easier to produce and maintain.

In addition to all the advantages of a rifle-free rifle, SRS has a feature that is very popular with shooters, and that is the SRS's caliber conversion function. Its rifle machine and magazine are completely versatile, and you can switch between several calibers by simply changing the barrel and the gun. The caliber conversion function gives the rifle greater flexibility in many types of missions, and the smaller caliber is also sufficient for combat in urban environments. Moreover, the same weapon can be used to convert a variety of caliber designs, so that the shooter only needs to familiarize himself with a rifle system, which is beneficial to reduce training costs and improve training efficiency.

The SRS rifle has four caliber support, .338 Rapp Amagnan, .308 Winchester Magnum, .300 Winchester (7.62X51mmNATO) and .243 Winchester, basically medium caliber Sniper rifle.

However, DTA later based on the SRS rifle, a series of large-caliber unsupported structure sniper rifles named HTI, meaning "Hard Target Interdiction". In terms of structural principle, the HTI rifle and the SRS rifle can be said to be identical, basically an amplified and reinforced SRS rifle.

HTI sniper rifles also have four calibers, .50BMG, .416 Barrett, .408 Cheyenne tactics and .375 Cheyenne tactics. However, two high-precision bullets of the Cheyenne tactics have appeared, but the .416 Barrett bullets have not yet appeared. Guo Tailai is considering whether to grab the front of Barrett and put the .416 Barrett ammunition first. It is also considered to be a special large-caliber sniper in the country. Or take the .460 Steyr out in advance? The ballistic performance of these two bullets is much stronger than the .50. But forget it, the bullets are too complicated, so don't be so troublesome.

Like SRS, HTI can be arbitrarily converted among these four calibers. The lengths of the four caliber barrels are all 29 inches, but the size of the muzzle retractor is different, so the length is slightly different, but the length is very close.

This time, basically, the sniper rifle design of the large and medium caliber is gathered. After pondering it, Guo Tailai still took a look at the calibre. Based on the SRS, he simply reduced the design of some casings and magazines. He used 5.45mm Soviet small caliber ammunition, 5.56mm NATO standard ammunition and 5.8mm88 sniper rifle. The heavy bombs used are included, thus forming a small-caliber series. Of course, Guo Tailai estimates that the domestic use of 5.8mm heavy bombs will not be used, so the logistical pressure is minimal.

Because of the use of a floating barrel and the bipod on the guard, unlike the Type 88, which is fixed to the barrel, the accuracy of the shot is less affected. In fact, the original 88-range range is not far away. Within a few hundred meters, this effect is really negligible.

However, the 620mm barrel of the same length as the 88 type is used, but the length of the small-diameter SRS is shorter than that of the 88 type due to the difference between the casing and the butt, and the weight is just four kilograms, which is also lighter than the 88 type. So little.

In this way, a structure of sniper rifles can meet the use of nine caliber bullets in three ranges of large, medium and small. After the arrival of .416 Barrett and .460 Steyr, add two more calibers, presumably for the current domestic troops. The use of it is enough?

Maybe the sister will be very happy to see it all.
