The sniper starts from the bright sword escape period

Chapter 224 Muzzle brakes and silencers.

Of course, one of the biggest advantages of this kind of Kepler scope is that it can correct the center of sight according to the point of impact anytime and anywhere, making the shooting of the sniper rifle more accurate.

There is no need to waste time and trouble to adjust the fixed position between the sniper rifle and the scope.

And not only that, the Kepler scope can also make the magnification higher, for example, it can be made into a 22x mirror, or a [-]x mirror or even higher.

As for why there was only an eight-fold mirror at most during World War II, and it was not very commonly used. Could it be that there is no way to manufacture a sight with a higher magnification!

This is of course not, but it is basically unnecessary, because the sniper rifles during World War II were all small-caliber rifles modified, and their calibers are all about 600 mm, so the effective range of the bullets is also between 1000 meters and [-] meters. .

And I also thought that the weight of the bullet head of the bullet is generally around ten grams because of the small caliber, so the wind resistance is poor, so basically if the distance is far away, if there is a little wind, the bullet will not know where it will be blown.

But it is different for the large-caliber anti-material rifles that became popular after the 80s. For example, the Barrett anti-material rifle with a 45mm caliber has a bullet weight of [-] grams. Four or five times the weight of the caliber bullet.

And because of the weight of the bullet, the bullet's ability to store speed is also strong. With the same initial velocity of the bullet, the supersonic flight distance of the 800mm bullet can reach 800 meters, while the [-]mm The supersonic flight distance of the bullet head is only [-] meters.

This also means that it is not necessary to equip a high-magnification scope for this kind of sniper rifle with a range of only 800 meters, because it is completely unnecessary. An eightfold scope is more than enough, and even a fourfold scope is barely enough.

But for Barrett, whose effective range can reach 800 meters, [-] mirrors are not enough, so the [-]mm sniper rifles like Barrett are equipped with a [-]x ratio at the beginning. scope.

Sniper rifles like the TAC50, which pursue high precision, have already used a [-]x magnification scope.

However, the magnification of the scope used by the most accurate M200 sniper rifle has reached 22 times.

Because the gun to be assembled with the Bailixiu scope is not an ordinary small-caliber rifle, but a large-caliber anti-tank rifle such as PTRD-41.

For an anti-tank rifle with a caliber of 64, a warhead weighing 2000 grams, and a bullet with a muzzle velocity of [-] meters per second, the supersonic flight distance of its bullets will naturally not be less than [-] meters.

Therefore, the sight with a magnification of [-]x is obviously not enough, so Xiucai Baili used a [-]x scope as soon as he came up.

That's right, the magnification of the first domestically produced scope produced by Bailixiu was set at [-] times. Only such a magnification can satisfy the ultra-long range of anti-material rifle bullets.

Of course, the high-magnification scope also has a very bad disadvantage, that is, the field of view is small. This is a disadvantage of many high-magnification scopes. The larger the magnification, the smaller the field of view of the scope.

This is why in modern sniper warfare, snipers are often equipped with an observer.

In addition to providing the target distance for the sniper, the observer has to observe the surroundings, so as not to be embarrassed by the sniper's aiming too hard and being touched by the enemy without being noticed.

Although the Soviet Union was puzzled by the PTRD-41 anti-tank rifle they wanted here, the Soviet State naturally looked down on this old-fashioned anti-tank rifle, so they were very generous and gave away a thousand of these anti-tank rifles. The tank rifle also comes with [-] rounds of [-]mm bullets.

Of course, this is not free, but it is still very cheap in comparison, but although the idea of ​​​​the anti-material sniper rifle proposed by Bailixiu is very good.

However, he did not choose to take more. You must know that the output of PTRD-41 anti-tank rifles was not low during World War II, at least [-] or more, so even if you ask Su to get [-], Su can immediately Take it out.

The main reason for this is that the idea put forward by Bailixiu is still in theory, and the actual combat has not yet produced results!

After Bailixiu got the PTRD-41 anti-tank rifle, he conducted a test shot.

Then I found that the recoil of this gun was not as exaggerated as in the rumors, one shot in the left shoulder, one shot in the right shoulder, and then went home to receive the medal.

Of course, if you think about it, if the recoil of this anti-tank rifle is really so exaggerated, then there will not be such a large output.

It's just that this anti-tank rifle wants to become an anti-material sniper rifle, and there is still a major flaw that needs to be corrected.

That's right, the defect is the muzzle brake. Like the anti-material sniper rifle like Barrett, the muzzle brake is also added to reduce the recoil.

Of course, unlike Barrett’s inverted V-shaped muzzle brake, the PTRD-41’s muzzle brake is flat. When shooting, the high-speed and high-pressure airflow does not jet towards the oblique rear like Barrett. Just spray left and right.

Therefore, the efficiency of the muzzle brake of such a muzzle brake is naturally not comparable to that of Barrett's muzzle brake, only 30.00%.

Barrett's inverted V-shaped brake has a braking efficiency of 70.00%.

This is also the main reason why Barrett can shoot continuously.

However, Bailixiu does not dislike the low efficiency of the PTRD-41 muzzle brake, mainly because using the muzzle brake on a sniper rifle will reveal the position of the sniper.

No matter whether it is spraying high-speed airflow to the left or right or backward, a large amount of dust will be raised. Even if it is shot in a snowy environment, it goes without saying that it will also raise a lot of snowflakes.

In Bailixiu's view, the most important thing for a sniper is to save his life, so hiding himself is the most important thing, so the three-piece suit for a sniper, in addition to the most important scope, the remaining silencer and auspicious Clothing is very important.

In particular, the muffler can not only greatly reduce the sound of shooting, but also reduce the high-speed and high-pressure airflow from the muzzle to the point where it can't blow the dust on the ground.

Before Bailixiu crossed, many people did not know where they heard the news that the sniper rifle equipped with a silencer would affect the accuracy of sniping.

Snipers pay attention to killing with one shot, so in order to complete the task, they should try to kill with one shot.

But I never thought about what would happen to the sniper after he fired without a silencer and was exposed.

Besides, the design of the muffler in the world before Bailixiu crossed was very reasonable, and it was no longer the stupid way of using the rubber ring to avoid the wind.

Therefore, installing a silencer has little effect on the sniper rifle. After all, the M200 is equipped with a special silencer when it leaves the factory.
