Chapter 861 Processing the Barrel (Part 2)

"We bring a high-strength steel." Lewis quickly replied: "The hardness and strength are relatively high, and the processing is very difficult."

"Understood." Guo Tai looked at the processing requirements and nodded. If calculated according to the performance of the M200 sniper rifle in his mind, the wall of the barrel will be thinner, which must be achieved with extremely high-performance steel.

Guo Tailai guessed that this design and selection of materials are for weight reduction. After all, the M200 he knows weighs 14 kilograms empty, which is comparable to the Barrett M82A1. The caliber is small, the power is small, but the weight is the same, which is obviously a defect. It should still be in the design process now, trying to achieve the purpose of weight reduction through higher grade steel.

Obviously, this not only increases the cost of materials, but also greatly increases the difficulty of processing. That is to say, during the design period, they need to verify the feasibility before finding Mr. T's name. Otherwise, if Guo Tailai is also sought for normal production, it is estimated that this gun will immediately become a sky-high price.

That's why some sizes are slightly different. The difference in the rifling angle and twist should be due to the fact that the shape has not yet been finalized, so the size will be different.

"If you want to lose weight." After a few glances, Guo Tai raised his head and said to Lewis: "In fact, simply consider high-strength titanium alloys directly! You know, the strength can definitely meet the needs. The heavy effect is even better.”

"Production must also be considered." Lewis agreed with Guo Tailai's statement, but still explained with a wry smile. Of course, using titanium alloy can reduce weight, but if you want to mass-produce, I am afraid that the cost will go to the sea.

In the dream of the future, in 2010, NEMO Arms of the United States launched an all-titanium AR rifle called [Ti] ONE. As the company advertised, this . The 308 Winchester caliber AR rifle is almost entirely made of titanium, only the bolt, firing pin and barrel are made of usual steel parts, while the upper and lower receivers, buffer tubes, bolt frame, and even the guard are used. Many components, including wood, are directly cut from titanium.

Although the unit price of titanium metal is not very expensive, due to the limited industrial processing level at that time, it was very difficult to directly cut titanium, which made this [Ti] ONE all-titanium rifle a veritable "local tyrant". "Gun", the price in the United States is as high as 95,904 US dollars, equivalent to RMB 620,000. This price has exceeded dozens of times that of ordinary AR rifles in the gun market.

Due to the difficulty in processing titanium, a large number of defective products also appeared during the production of the gun. Perhaps considering the purchasing power of users and reducing project costs, NEMO Arms also introduced these defective guns to the market. , which is on sale for $49,789, which is nearly 50% off.

That was the price ten years later. One can imagine how high the price of this gun would be if Guo Tailai could process a titanium alloy barrel for them now.

When Guo Tailai mentioned the titanium alloy barrel, Lewis could only smile wryly, what else?

Continue to turn back, and sure enough, the drawings behind are another barrel of different thickness. These barrels are processed to verify the design.

"I can achieve higher precision than this." After reading the drawings, Guo Tailai said to Lewis: "Of course, only pay according to the accuracy required by the drawings, don't worry. But..."

Hearing that Guo Tai said that higher precision could be achieved, Lewis almost said that there was no need for it, and finally he was relieved when he heard the following sentence. However, Guo Tailai's only two words made Lewis nervous for a while.

"According to your drawings, I can roughly guess that your sniper rifle should be an anti-personnel weapon with an effective range of about 2,000 meters." Guo Tailai ignored Lewis's mood and directly expressed his thoughts : "Although I haven't seen the bullet, I guess it should be a high-precision bullet processed by CNC machining from a homogeneous metal strip. But with all due respect, your rifling design may restrict your shooting range and shooting accuracy."

"What?" Lewis almost cried out. The effective range and design of the bullet that Guo Tailai guessed are not bad at all. It is the numbers and methods that Guo Tailai said. It is unbelievable that he can guess so much just by relying on the blueprint of the barrel.

But what is even more surprising is that Guo Tailai directly said that the rifling design will affect the range and shooting accuracy? How is this calculated? how is this possible?

"Of course, I will process according to the drawings. I charge a lot. I hope you are mentally prepared." Guo Tailai said with a smile: "But I guarantee the time and quality. If the price is negotiated, you can get it by this time tomorrow." Finished barrel. Also, I have some suggestions on rifling design, if you need it, you can also buy it at a reasonable price, believe me, it will save you a lot of time."

"How much?" Dare to find Mr. T, Xia An's tactics must have been mentally prepared for the high price, Lewis directly asked Guo Tailai for the price.

"Please talk to my assistant about bargaining." Guo Tailai politely asked Lin Jiayi to take his place, and started bargaining with Lewis, but after wandering around for a while, he went to find Mr. Pagani.

It may be because Guo Tailai did not expect Guo Tailai to propose his suggestion on the modification of the rifling. Out of trust in his idol, Lewis communicated with the company on the phone for more than an hour, and finally reached an agreement.

Originally, Lin Jiayi had asked for 1.5 million US dollars for the two barrels, which was based on the customized price of the high-precision barrels that Guo Tailai had mentioned to Zhao Xiangbei at the beginning, but after a few years, the processing technology has also developed. Some processing methods will inevitably bring down the price, so we finally talked about 750,000 US dollars.

However, there are prerequisites for this price. Guo Tailai will provide Xia An Tactical with a rifling design. If the new rifling design is better than their own design, Xia An Tactical will provide a design fee of two million US dollars. Of course, Guo Tailai's rifling design must be detailed drawings and reflected in the contract. With a detailed contract, I'm not afraid that Xia'an Company will renege on their bills.

Based on this premise of cooperation, the price of the two barrels will be approved at half price. After the cooperation was negotiated, the two parties drew up a contract and signed it. Guo Tailai also successfully obtained the five round steel rods brought by Lewis to process the barrel.

Xia'an Company's contract is very strict. Except for the finished products, all the debris, leftovers and even defective products in the processing process must be taken away. It is said that this is a brand new steel and cannot be leaked.

Guo Tailai didn't care about this at all. In just one day, Lewis got four barrels, two of the original design and two of Guo Tailai's modified designs.
