Chapter 671: Sniper Rifle (Part 2)

More than a week, ten days to be exact, except for the first few days when Guo Tailai learned about the advantages and disadvantages of existing sniper rifles with senior snipers from the Beijing Military Region, the rest of the time was Guo Tailai's thinking and making.

In the past few days, Guo Tailai has been focusing on nothing else, except for calling home to say hello, all other time is spent on it. Of course, the effect is also very outstanding.

Two sniper rifles with chrome-plated interiors of pure titanium alloy barrels and ten sniper rifles with special steel barrels. Twelve white light sniper scopes, twelve matching silencers, and dozens of matching magazines.

This time, Guo Tailai paid more attention. He only put a T-shaped mark on the top of the pure titanium alloy barrel, and the others were treated as ordinary guns without this mark.

When all this was done, it was already after Christmas. Guo Tailai originally wanted to spend a few days with his senior sister and stay at home to rest when they had time, but the senior sister disagreed and hurried back to the Beijing military area with these sniper rifles.

To Guo Tailai's surprise, there were not only several generals from the Beijing military region waiting for Guo Tailai and Zhao Yanyan on the shooting range, but General Chu from the assembly side was also present again, and Zhao Xiangbei was also present. Take your new gun very seriously.

Faced with this situation, Guo Tailai could only be patient and introduce this gun in detail.

"This gun was born out of the British L115A1. The ordinary rifle weighs 6.5 kilograms and is 1300 millimeters long. It fires NATO standard .338 caliber Lapua special sniper bullets, with a range of up to 1600 meters and a muzzle velocity of 936 meters per second. This gun is manually operated and equipped with a 5-round magazine. It is equipped with a folding stock so that soldiers can carry it in a backpack. It is also equipped with an adjustable cheek piece so that soldiers can Elevated cheeks for more comfort, allowing for natural line of sight alignment with sights."

"In addition, the muzzle of the new gun is equipped with a silencer, which reduces the fire and noise when firing, and reduces the chance of being discovered by the enemy. The magnification of the scope is increased to 25 times, which can observe targets at a longer distance."

Because the barrel is made of the latest special steel, the new gun is 0.3kg lighter than the original L115A3, only 6.5kg in weight. The one made of titanium alloy is lighter, only 5 kg, and the advantages of weight and volume are very prominent.

"The design idea of ​​this gun is to achieve the first hit regardless of whether the barrel is clean or not. The structural design has considered the problem of antifreeze, and designed a special surface protection layer, shallow grooves to absorb ice debris, and three positions. Safety handle, manual bolt opening and closing mechanism that slides freely. But it is not only suitable for use in cold regions, it can operate reliably at -40°C, and it can be used in tropical regions, and its performance in hot and humid climates is also quite good. .”

After briefly speaking, Guo Tailai made a supplementary summary: "Of course, these are design goals, and whether they can be met or not requires a lot of testing."

If a research institute in China said so, they would definitely be scoffed at by a group of people. How unreliable is it to dare to brag like this without being tested? But it was brought out by Guo Tailai, so no one doubted it, they only expected that the performance would be better than this.

Not for anything else, just because the things that Guo Tailai has produced before have always been better than the data on paper. What Guo Tailai told everyone is usually the most conservative data under certain extreme circumstances.

With General Sun's order, the six snipers were divided into three groups, each with a new gun, to be precise, each with a complete set of parts for the new gun, carefully assembled by himself, and then began to debug and return to zero.

Because it is an improved version of AWM, the six senior snipers do not need to relearn to use it at all. Just listening to Guo Tailai's introduction just now is enough for them to master the method of use, and the rest is to test.

Three groups of snipers use three different bullets. One is the domestically produced .338 bullet according to the bullet standard, the other is the imported American-made .338 bullet, and the other is the bullet shell made by Guo Tailai himself, and then the same type of special sniper bullet that is packed with high precision by the factory. Even the propellant uses the latest high-energy propellant, a new high-energy propellant with higher energy burning rate, more uniform burning time, shorter burning time and larger volume expansion. Of course, it is also more expensive.

For this high-precision bullet alone, Guo Tailai produced thousands of them for testing, and spent the first two days making bullets.

Today's weather is fine, breezy, minus five degrees, dry, ideal for gun testing.

Everyone knows that Guo Tailai's manual processing is extremely accurate. Snipers quickly sensed this when they zeroed in.

In the beginning, everyone habitually returned to zero according to 100 meters. The basic method of zeroing is the same, follow the steps of "shooting - adjust the sight according to the deviation - then shoot and verify" until the final calibration is completed. Under normal circumstances, experienced veterans of this process have to cycle three or four times.

But for these new guns, Guo Tailai has made basic adjustments, and the processing accuracy is extremely high, resulting in a very high matching degree between the scope and the receiver. In addition, the magnification is extremely high, and it can be adjusted very finely. In the first round of five shots, several snipers found that they basically overlapped, and only adjusted once. The shooting at a 100-meter target basically meant where to hit.

At a distance of 100 meters, each person took ten shots, and then calculated the accuracy based on the distribution on the target paper. At this distance, the difference between the three kinds of ammunition is not very big, and the difference is only one or two millimeters. The group with the worst score can also distribute the impact points of ten bullets within a circle with a diameter of 14 millimeters. According to the calculation of the density, it should be within Within 0.5moa.

Just seeing this result, everyone around was already very pleasantly surprised. You know, the diameter of the bullet is only 8.6 mm, and the maximum deviation within 100 meters is less than the diameter of a bullet. At worst, it can rub the target!

The target was changed to 200 meters, still ten shots per person. This time the result was a little different. The imported bullets and the bullets made by Guo Tailai are still high in accuracy, but the domestic bullets are slightly worse. They can still be maintained at 0.5moa, but the dispersion of the other two is obviously smaller.

300 meters back to zero again, the target of 500 meters, the result of ten shots, the maximum deviation of domestic bullets has reached 10 cm, and the deviation radius is 10 cm, which is almost within the accuracy of 0.7moa. However, the imported bullets can still be kept at 0.5moa. As for the bullets made by Guo Tailai himself, it is even more amazing, 0.3moa, and the maximum deviation radius is less than 4.5cm.

After returning to zero at a distance of 600 meters, the accuracy of domestic bullets for a target of 800 meters has dropped to 1.25 moa, and the deviation radius has reached 28 cm. Imported bullets are still around 0.87moa, with a deviation radius of 20cm. Guo Tailai's bullet still maintains a scary accuracy, slightly lower than 0.6moa, and the deviation radius is less than 14cm.

Seeing this result, not to mention the onlookers, even the sniper who shot this result was extremely surprised.
