Story
Until the 1980s, American soldiers used M21 sniper rifles, which were based on the semi-automatic M14. However, the M21 soon began to fall into disrepair, and getting spare parts for the weapon was quite problematic. Due to the changed situation in the world, American soldiers had to carry out their military operations in the Near and Middle East. In open desert spaces, the military needed a weapon that could provide high-precision shooting at a distance of at least 1 thousand m. Due to the requirements imposed by the Marine Corps, US weapons designers had to design a new sniper rifle with a longitudinally sliding bolt, a polymer stock and a barrel made of stainless steel A competition was announced to create such a rifle unit. In the end, the finalists were the SSG69 Steyr and the Remington Model 700BDL. After the tests, Remington won, and in 1987 the United States Army adopted the M24 rifle.

Description
M24 rifle with a monolithic stock, for the manufacture of which combined polymer materials are used: glass and carbon fibers, polymer foam reinforced with Kevlar. At the bottom of the fore-end and butt there are special mounting swivels, through which the weapon is equipped with a tactical belt. Adjustable folding bipods are attached to the forend. In the version of the rifle intended for use by special police forces, an integrated laser designator (laser designator) is provided at the end of the forend. The shooter has the ability to adjust the length of the butt up to 5 cm, adjusting the rifle to his anthropometric data.
About sights
The M24A1 uses the standard Leupold Ultra M3A or Mk4 LR/T M1 optical sight. They are characterized by a fixed magnification, using a range-determining factor and a special compensator, the task of which is to take into account the decrease in the trajectory of the fired projectile. Additionally, the rifle is equipped with an open mechanical sighting device: a diopter rear sight and a front sight. Initially, sights on sniper rifles were installed using special brackets. Later, a standard Picatinny rail was used for this purpose.
About the trunk
The M24 rifle is equipped with a barrel made from high-quality stainless steel. The length of this element was 60.9 cm. The barrel was subjected to special processing, allowing the use of this sniper weapon with 7.62 mm NATO-style M118SB cartridges. The barrel is provided with a 5R drill, which is represented by five rifling. According to weapons experts, in this drill, which is a development, the rifling has rounded edges. Unlike other sniper systems with a bevel angle of 90 degrees, in the M24 rifle it was 65. This was done specifically in order to minimize friction and contamination as much as possible. The rifling pitch length is 2.86 cm. The service life of the barrel is no more than 5 thousand shots. According to military experts, due to the odd number of rifling, none of them are at an angle of 180 degrees, which reduces the deformation of the projectile as it moves along the barrel channel.
Excerpt characterizing the M24 (sniper rifle)
Rostov looked at what was happening in front of him as if he were being persecuted. He instinctively felt that if he now attacked the French dragoons with the hussars, they would not resist; but if you hit, you had to do it now, this minute, otherwise it will be too late. He looked around him. The captain, standing next to him, did not take his eyes off the cavalry below in the same way. “Andrey Sevastyanich,” said Rostov, “after all, we will doubt them...” “It would be a dashing thing,” said the captain, “but in fact... Rostov, without listening to him, pushed his horse, galloped ahead of the squadron, and before he had time to command the movement, how the entire squadron, experiencing the same thing as him, set off after him. Rostov himself did not know how and why he did it. He did all this, as he did on the hunt, without thinking, without thinking. He saw that the dragoons were close, that they were galloping, upset; he knew that they could not stand it, he knew that there was only one minute that would not return if he missed it. The bullets squealed and whistled around him so excitedly, the horse begged forward so eagerly that he could not stand it. He touched his horse, gave the command, and at the same moment, hearing behind him the sound of the stomping of his deployed squadron, at full trot, he began to descend towards the dragoons down the mountain. As soon as they went downhill, their trot gait involuntarily turned into a gallop, which became faster and faster as they approached their lancers and the French dragoons galloping behind them. The dragoons were close. The front ones, seeing the hussars, began to turn back, the rear ones stopped. With the feeling with which he rushed across the wolf, Rostov, releasing his bottom at full speed, galloped across the frustrated ranks of the French dragoons. One lancer stopped, one foot fell to the ground so as not to be crushed, one riderless horse got mixed up with the hussars. Almost all the French dragoons galloped back. Rostov, having chosen one of them on a gray horse, set off after him. On the way he ran into a bush; a good horse carried him over, and, barely able to cope in the saddle, Nikolai saw that in a few moments he would catch up with the enemy whom he had chosen as his target. This Frenchman was probably an officer - judging by his uniform, he was bent over and galloping on his gray horse, urging it on with a saber. A moment later, Rostov’s horse hit the rear of the officer’s horse with its chest, almost knocking it down, and at the same moment Rostov, without knowing why, raised his saber and hit the Frenchman with it. The instant he did this, all the animation in Rostov suddenly disappeared. The officer fell not so much from the blow of the saber, which only slightly cut his arm above the elbow, but from the push of the horse and from fear. Rostov, holding back his horse, looked for his enemy with his eyes to see whom he had defeated. The French dragoon officer was jumping on the ground with one foot, the other was caught in the stirrup. He, squinting in fear, as if expecting a new blow every second, wrinkled his face and looked up at Rostov with an expression of horror. His face, pale and splattered with dirt, blond, young, with a hole in the chin and light blue eyes, was not the face of a battlefield, not an enemy’s face, but a very simple indoor face. Even before Rostov decided what he would do with him, the officer shouted: “Je me rends!” [I give up!] In a hurry, he wanted and could not untangle his leg from the stirrup and, without taking his frightened blue eyes off, looked at Rostov. The hussars jumped up and freed his leg and put him on the saddle. Hussars from different sides fiddled with the dragoons: one was wounded, but, with his face covered in blood, did not give up his horse; the other, hugging the hussar, sat on the croup of his horse; the third, supported by a hussar, climbed onto his horse. The French infantry ran ahead, shooting. The hussars hastily galloped back with their prisoners. Rostov galloped back with the others, experiencing some kind of unpleasant feeling that squeezed his heart. Something unclear, confusing, which he could not explain to himself, was revealed to him by the capture of this officer and the blow he dealt him. Count Osterman Tolstoy met the returning hussars, called Rostov, thanked him and said that he would report to the sovereign about his brave deed and would ask for the St. George Cross for him. When Rostov was demanded to appear before Count Osterman, he, remembering that his attack had been launched without orders, was fully convinced that the boss was demanding him in order to punish him for his unauthorized act. Therefore, Osterman’s flattering words and the promise of a reward should have struck Rostov all the more joyfully; but the same unpleasant, unclear feeling sickened him morally. “What the hell is tormenting me? – he asked himself, driving away from the general. - Ilyin? No, he's intact. Have I embarrassed myself in any way? No. Everything is wrong! “Something else tormented him, like remorse.” - Yes, yes, this French officer with a hole. And I remember well how my hand stopped when I raised it.”
About the options

Recharge principle
From the point of view of the reloading method, all rifles can be divided into two types:
- Bolt-action rifles have higher accuracy and shot accuracy, they are easy to clean and maintain, but they allow the hunter to quickly fire the next shot, which is extremely necessary for some types of hunting.
- Semi-automatic self-loading rifles - allow you to quickly fire the second and subsequent shots, but at the same time they have less accuracy and accuracy of the shot, and require more thorough cleaning and maintenance.
