Now the time is already the beginning of June, Chen Er's heart can't help but be anxious, seeing that a big war is coming, he knows what will happen but he can't stop it, and a deep sense of powerlessness also makes Chen Er seem more and more tired. Walking in the research room of the special research team, Chen Er also had no intention of looking at the materials sent by the factory director.

Wen Jing also seemed to see that the team leader had something on her mind, and asked carefully: "Team Leader Chen, what's wrong with you, is there anything uncomfortable, I see that you have been frowning for a long time, have you encountered any problems?" Although I am just getting started, I believe that everything is not up to the truth, and Team Leader Chen does not need to be too anxious, and he will get better slowly. ”

Listening to Wen Jing's words, Chen Er nodded, he was indeed too worried, after all, it was the history of life, even if he crossed over, some major historical events were still powerless to change, since this is the case, then he should work his work. The only thing that can be done now is to increase the level of weapons in the army as much as possible, and sacrifice the lives of some soldiers.

After making up his mind, Chen Er picked up a blank drawing and drew it, anyway, with the title of the special research group, even if he researched something strange, everyone would not say anything, which was more conducive to his own waving. In less than half an hour, the drawings of the firearms that have been brand new are on the paper, Chen Er looked at it and nodded with satisfaction, the 63-type automatic rifle, this is the first rifle developed by itself in China's modern history, and it can be regarded as a real military product of its own.

Compared with the Type 63 automatic rifle and the Type 56 semi-automatic rifle, it has been further improved, the Type 63 automatic rifle automatic machine borrows from the structure of the Type 56 submachine gun, the bolt is rotated and locked, and the spiral protrusion on the nose is matched with the spiral groove on the frame, and the bolt frame drives the nose to complete the opening and locking actions and forward and backward movements. Most of the structural parameters were the same as those of the Type 56 submachine gun. The Type 63 automaton had two improvements, one was to separate the piston from the frame, and the other was to reduce the distance between the center of mass of the automaton and the axis of the barrel. Both of them are derived from reducing the power couple and increasing the point.

The receiver is a machined forging receiver, and the barrel is connected to the receiver with a threaded connection. The receiver structure is similar to that of the Type 56 semi-automatic rifle, with the front and rear legs protruding from the receiver to snap into the shooter mount and the butt to the body. The front part of the receiver is the barrel hole and the locking bearing surface, the middle of the receiver is connected by the front foot, the rear part of the receiver is connected by the rear foot and the rear impact surface, and the two sides of the receiver are relatively thin, 2.5mm. Overall, the receiver is stiff, strong enough, and not heavy.

The gas guide system was completely redesigned, and the gas regulator structure was adopted on the rifle, and the piston and adjusting plug were loaded into the piston barrel on the gas guide hoop from the front. There is a gas regulating device, under normal conditions with a small air hole shooting, the automaton moves smoothly, reduces the impact to ensure the improvement of shooting accuracy, under special circumstances, the automatic machine with a large air hole shooting has a large energy, to ensure the reliability of the action, at the same time, a large number of shooting is carried out under normal conditions, the life of the whole gun can also be guaranteed. The structure of the gas conduction system is relatively simple, the assembly, disassembly and conversion are very convenient, and the performance of the power parameters is also very reasonable, which is a powerful measure to ensure reliability.

The machine is also redesigned, with a rotary hammer and a hook to block iron. Its important feature is that the hammer spring still uses cylindrical coil springs, which are more convenient to manufacture and use. The machine is still assembled into independent parts using the machine bracket, which can be easily assembled and disassembled on the receiver when the whole gun is disassembled and combined. The process manufacturing is simpler than that of the Type 56 submachine gun, and the blocking iron, hook, and bracket can all be stamped and formed. The action of the shooter is reliable, and the service is also very good.

The ammunition supply is made of O.75mm thick steel plate punching and welding combination, and the structure is the same as that of the Type 56 submachine gun magazine, except that it is changed to 2O ammunition loading, and the empty compartment hang-up guide groove is added, and the ammunition supply route is adjusted to make it more reliable. At the same time, it also maintains the function of the Type 56 semi-automatic rifle, which can press bullets into the magazine through the guide slot in the front of the frame without removing the magazine. The butt is the same as the Type 56 semi-automatic rifle, with a full-shaped long wooden butt, holding the neck of the butt, and pulling the trigger with the index finger, mainly to facilitate the holding of the stab, and if necessary, you can also immediately pull the trigger to shoot.

The bayonet was put forward as a prominent requirement on the Type 63, so the fixed foldable bayonet like the Type 56 semi-automatic rifle was still adopted. The knife-shaped section is ** type, the blade length is 31omm, and the tip of the knife is sharp to enhance the killing power.

The ruler and crosshair of the sighting device are the same as those of the Type 56 submachine gun, and the circular vernier of the curved ruler base is adopted.

Due to the fact that the Type 63 automatic rifle adopts a series of technical measures according to the performance requirements in the main structure, on the whole, this automatic rifle meets the tactical and technical requirements and has good performance, which mainly has the following points:

The tactical performance and requirements of the rifle were highlighted in general, and the company firing was realized, the firepower of the rifle was strengthened, and the combat performance was improved.

The shooting accuracy is good, the single accuracy is equivalent to the five or six type semi-automatic rifle, the 1oom distance on the R5o is about 5cm, the point ** degree is much better than the five or six submachine guns, when shooting, the gun is smooth, and the muzzle does not jump.

Reliable movements, able to shoot reliably under special conditions such as wind and sand, severe cold, and swimming across rivers, the 63-style passed these severe tests during the national shooting range test. To meet the life of 15, OOO requirements, the five or six type semi-automatic rifle only 6, ooo life, six three type neither increased weight, nor did not use special materials, but increased the life of more than 1 times, mainly the structural design is reasonable, the power parameters are properly matched, the reliability, accuracy, life, weight of the most important performance, through the overall technical measures of the organic unity.

In terms of combat service performance, the rifle maintains the characteristics of the rifle, such as highlighting the role of the bayonet, strengthening the rigidity and length of the bayonet, and improving the convenience and strength of the gun when fighting the stab; The barrel is long, to ensure the power of the effective range, there is an empty compartment hang-up, the upper pressure mechanism brings great convenience for time and at any time, the whole gun structure is simple, and the disassembly and combination are quick and convenient.

Although it seems that the magazine has only increased by ten bullets, it has greatly improved its firepower, and Chen Er believes that this is definitely an epoch-making weapon. After drawing the drawings, Chen Er began to prepare for the production of sample guns, first the processing of each individual part, because the equipment of the whole factory can be used at will, so although the machine tools here seem to be relatively backward, but with the great help of the machine tool masters, Chen Er has completed the processing of most of the gun parts in more than a week.

Watching Chen Erben walk between various machine tools and masters, and asking something from time to time, Wen Jing felt that she was really useless at this time, thinking that she was also a talented girl of Beiping Women's Normal University, but now she is like a primary school student, she suddenly felt a little hurt in her heart, it seems that she has to work harder, otherwise she will not be able to keep up with the pace of the team leader.

After another three days, Chen Er finally got the last few parts, and at this time, he finally let out a big sigh of relief, and handed over Li Jun to the shooting range, Li Jun asked suspiciously: "Second brother, what did you ask me to come to the shooting range for?" ”

Chen Er pointed to the bag on the ground and said, "See for yourself." Li Jun squatted down and opened the bag to see that a pile of firearm parts were presented in front of him, and there were four or five magazines, Li Jun suddenly said with joy on his face: "Second brother, could it be that you have made something good again, and you want me to test the gun." ”

Chen Er didn't speak, squatted down and began to assemble it, and in less than five minutes, a brand-new firearm appeared in his hand, inserted the magazine up, Chen Er said, "How about it, let's try it." Without waiting for Chen Er to explain the specific number of firearms, Li Jun took it and lay down and pulled the bolt, shot at the target and said: "Second brother, this is nothing special, I think that in addition to the accuracy of the previous 50-type semi-automatic rifle, there are a little more bullets, and the other advantages are really not seen." ”

Chen Er didn't explain, changed a magazine for him, casually wrenched it on a protrusion on the firearm, and said, "Now you try again." With the pull of the trigger, twenty bullets were fired out at once, Li Jun was stunned for a moment before saying: "Second brother, how is this like a machine gun, a trigger and a shuttle bullet is out, this is still a rifle, it is simply a miniature version of the machine gun." ”

Chen Er said: "Of course it's a rifle, but this is my latest research on a fully automatic rifle, which can shoot both point and shot, so it can be said that it has been greatly improved in terms of firepower, and the weight of the whole gun is still about the same as the 50 type, what do you think of this gun?" ”

Li Jun thought for a while and said: "If you want me to say just one word, Niu, anyway, this is the best rifle I think, by the way, second brother, this rifle has not been named yet, I think it is simply called Chen's automatic rifle, anyway, it is also researched by you, and it is nothing to have your surname, many of those foreign rifles are named after those weapon masters." ”

Chen Er smiled awkwardly, and said in his heart what kind of weapon master he was, but because of the reason of the crossing, he took the things that were not from this era and used them in advance, and hurriedly said: "Let's talk about this again, I haven't reported to the master yet, let's listen to the master's opinion when the time comes." ”

With this brand-new rifle, Chen Er came to Wang Shengli's office, and simply said to Wang Shengli, Wang Shengli was so happy that he couldn't keep his mouth shut, good guy, this apprentice of his own is really a talent in this area, this has just been semi-automatic for less than a month, this fully automatic rifle is coming out, if you follow this research degree, maybe it is not a problem to point to any aircraft cannon. encouraged Chen Er, Wang Shengli took this treasure to report to his superiors, after all, if the firearms can reach the number of jù mentioned by Chen Er, it will definitely be a major innovation in the history of China's light weapons.

Time is slowly on the night of June 24th, Chen Er is lying in bed alone but can't sleep, tomorrow is June 25th, thousands of kilometers away is being dispatched troops, the Korean War is finally about to break out.
