M40 and M24 repeating sniper rifles
Even during the Vietnam War, the question of sniper rifles with better accuracy rates arose. The Winchester repeating rifle did not completely satisfy customers. In 1966, the Marine Corps accepted as a sniper rifle under the designation M40 the Remington Model 700 commercial repeating rifle chambered for the .308 Winchester cartridge with a Redfield scope of variable magnification 3x-9x.
Model 700 was released by Remington Arms in 1962 based on M. Walker’s design, and within the first five years it had already earned popularity among athletes and hunters, so its choice was quite understandable.
7.62 mm M40A1 repeating sniper rifle with a McMillan plastic stock and a 3x12 Schmidt und Bender optical sight. The night attachment “Simrad” is installed on the optical sight.
The chamber was chambered for the stock 7.62x51 NATO round. For the conversion, rifles of the Varmint modification were taken, and with a matte finish on the external surfaces. As the service life of the M40 expired, they were replaced in units by the M40A1 modification, which was assembled, debugged and tested in the workshops of the Marine Corps Training Center. The M40A1 was assembled on the basis of the Model 700 from components produced by a number of companies:
– the standard barrel was replaced with an Artkinsen barrel made of stainless steel;
– the wooden stock was replaced with a plastic one made by McMillan, reinforced with fiberglass;
– the aluminum trigger guard with the lower hinged magazine cover was replaced with steel ones from the Model 70 Winchester rifle;
– a “Yunertle” sight with a magnification of 10x was installed. The sighting range is up to 1000 m, the field of view is 1.7–2° (at a distance of 100 m this is 3 m), and the resolution is about 5 seconds. The rifle and scope are coated with a matte epoxy coating that prevents glare and also serves as a primer for camouflage paint to suit the terrain and time of year.
The kit includes a night attachment of the amplifying type “Simrad” KN200/KN200F, which is attached to the sight lens without additional adjustment. KN200F allows you to detect a person at a distance of up to 700 m in moonlight and up to 560 m in starlight.
When using a 7.62 mm match grade cartridge, the M40A1 can reliably hit a live target at a range of up to 914 mm (1000 yards). At this range, the diameter of the hit dispersion circle for a series of 5 shots should not exceed 35 cm. The deviation of hits from the aiming point when firing from a rest is 38 mm at a distance of 300 m.
For training snipers, a 5.6 mm rifle chambered for .22 LR is used, which is similar in appearance, weight, balancing, and trigger mechanism behavior to the M40A1. Its accuracy and accuracy indicators at a range of 100 m are similar to the 7.62 mm prototype at a range of 600 m. This allows not only to reduce the cost of sniper training, but also to use smaller shooting ranges.
The US FBI snipers also adopted the M40A1 from the Marine Corps - apparently, the location of the FBI Academy in Quantico next to the Marine Corps Training Center played a role.
7.62 mm M24 repeating sniper rifle on a bipod, standing on a box-capper
To replace the M21 rifle in the army, the US Department of Defense in 1980 issued requirements for the SWS (sniper weapon system) program, developed taking into account the operating experience of the M40 and M40A1 in the Marine Corps. M118 cartridges of the 7.62x51 type or reinforced .300 Winchester Magnum were assumed. In 1986, the requirements were clarified, and in 1987, from a number of contenders (among which was the Austrian SSG), the same Remington Model 700 chambered for the 300 Winchester Magnum cartridge was chosen. In tests, this rifle at ranges up to 500 m showed accuracy similar to the Austrian SSG, at a range of 700–800 m slightly better accuracy. The rifle was designated M24.
The bore of the heavy free-floating barrel has 5 grooves. The barrel is threaded into the receiver so that the box covers the barrel. The rotary sliding bolt of the rifle (“long-stroke bolt” of the M70 system) has two lugs, the head of the cartridge case is placed in its cup, and an ejector and a spring-loaded reflector are mounted there, pushing the cartridge case out of the receiver window after removal from the chamber. This ejection of the cartridge case is an advantage of the Remington bolt, since it allows reloading with the least noise. In addition, the absence of a cutout in the combat cylinder for the passage of the reflector and the insertion of the bolt cup into the chamber make locking the barrel more reliable and safe. The case head is surrounded by three concentric rings - the bolt cup, the chamber and the receiver - and is well centered. The bolt lugs fit into the grooves of the receiver. A trigger with a combat cock is placed on the tail of the striker, covered with a rear cover that serves as a finger grip. The curved bolt handle in the locked position fits into the recess of the stock above the trigger guard and creates an additional bolt stop. The bolt is held in the receiver by a latch with a button.
The one-piece rifle stock was developed by H-S Precision and is made of Kevlar with the addition of graphite, reinforced with fiberglass, the main longitudinal loads are absorbed by an aluminum strip placed inside. The adjustable buttstock is mounted on three rods and can be extended up to 70mm. There is a “cheek” on the butt.
The main components of the Remington Model 700 rifle. Clockwise from top left: safety catch, trigger cover, receiver, bolt, receiver grooves for the optical sight bracket, barrel, barrel lug, magazine, magazine hinged cover, trigger, trigger guard with screw for mounting in the stock
The rifle uses the M/40X system trigger, assembled in a separate housing at the bottom of the receiver. The trigger force is adjustable from 0.9 to 3.6 kgf. A safety lever is mounted on the right side of the body; its head protrudes to the right of the bolt and has two positions - “safety” (“S”) and “fire” (“F”). The double-row magazine cover can be folded down for inspection and cleaning. To attach the belt, there are three swivels at the bottom of the stock, so it is possible to use the belt to hold it when shooting in a standing or sitting position without a stop - similar to sports or hunting rifles. A folding bipod of the Harris Bipod type is attached to the top swivel, and the bipod mount has its own eyelet (swivel) for a gun belt.
The rifle is combined with the M3 “Ultra” 10x or MZA “Leupold” sight with a reticle corresponding to the cartridges. The sight bracket has a base plate with four screws; collapsible rings are installed on the plate, in which the sight body is secured. There are spare removable sights with an open adjustable iron sight. The standard AN/PVS-4 amplifier type sight, which allows effective shooting up to 300 m, has been adopted as a night sight; it must be replaced by a new one, developed under the NSSS project.
When firing M118 cartridges at a distance of 550 m, the diameter of the dispersion circle does not exceed 30.5 cm.
The M24 is also used by the US police - primarily in SWAT teams. Based on the M24, a “medium sniper rifle” MSR project is being developed for “counter-sniper” combat.

The M24 7.62 mm sniper rifle was created in 1988 on the basis of the Remington 700 sporting rifle. The M24 has a 609 mm long stainless steel barrel, specially treated to fire M118SB 7.62 mm NATO sniper ammunition. The barrel has a Remington-designed 5R drill, which has 5 grooves with rounded edges (to reduce friction). The rifling pitch is 1 turn per 286 mm. The butt plate is adjustable to a length of 69 mm back and forth to suit any shooter.
In the mid-1980s, the US Army came to the conclusion that a completely new sniper system was needed, consisting of a rifle, scope, shipping case, accessories and specially designed and manufactured ammunition, the M118 cartridge with a special 7.62 mm caliber bullet. The task was complicated by the requirement that the rifle could be converted to use the .300 Winchester Magnum cartridge if, based on the results of long-term testing and combat use, it showed better performance.
These requirements were presented to small arms manufacturers in early 1986. Bids had to be submitted by November of that year, and the contract was awarded in July 1987. The winner of the competition was Remington Arms. This company already had some experience in the production of army sniper rifles: it was the company that supplied the M40 rifle to the US Marine Corps. The designers chose a repeating rifle with a long stroke bolt and a stock made of synthetic materials.
After researching various types of plastics, a graphite-kevlar composition with an aluminum core was selected. The stock is adjustable. Then open and optical sights, a carrying case and other accessories were developed. Barrels with different rifling were practically tested, and in the end one was found in which a bullet weighing 173 grains remained stable throughout the entire trajectory.
After the prototype was accepted, the company produced 25 rifles for full-scale testing, during which reliability, accuracy, endurance and many other indicators were examined. These tests were completed in July 1988, after which mass production of the rifle began, and the first batch of one hundred units of a total order of 2,510 rifles entered the army in October 1988.
The M24 sniper rifle is essentially a Remington M700 rifle with a specially cut barrel and a special M/40X trigger. The M24 has a 609mm stainless steel barrel specially treated to fire M118SB 7.62mm NATO sniper ammunition. The barrel has a Remington-designed 5R drill, which has 5 grooves with rounded edges (to reduce friction). The rifling pitch is 1 turn per 286 mm. The butt plate is adjustable to a length of 69 mm back and forth to suit any shooter.
The sniper system consists of a rifle, a bipod, a laser-cut daytime optical sight, an open sight, cleaning accessories, a soft case for carrying the rifle, a case for the optical sight, and a case for carrying the entire system. The entire system in the transport case weighs 25.4 kg.
The Leupold-Stewens M3 Ultra has a fixed magnification of 10x or 12x, a range scale and a compensator to account for bullet drop. The rifle is designed to use M118SB sniper cartridges. Sights are designed for the M118SB cartridge. The use of other 7.62 mm NATO cartridges requires re-shooting the weapon. When using standard M118SB sniper cartridges, the accuracy of the M24 is approximately equal to that of the SVD with the standard 7N1 sniper cartridge. The rifle barrel is designed for 5000 shots. It is guaranteed that the accuracy of fire will not exceed the initial one by more than 2 times.
Subsequently, an M24 sniper scope, flash suppressor, and target acquisition device were added to the system. Currently, the M24 sniper system is supplied to paratroopers, special forces units and infantry battalions.

Military officials decided it was time to replace the M21 rifle that was in service with something more modern. As a result, in 1980, requirements were announced for a new sniper rifle, which was supposed to have a longitudinally sliding bolt, a polymer stock and a stainless steel barrel.

when shooting
The developers' eyes once again turned to the Remington 700 model, or more precisely to the bolt group of this weapon, which serves as the basis for a large family of hunting and sporting rifles.
As a result of the competition with the participation of the Steyr SSG rifle, the Remington model - Remington Model 700BDL - won. According to the results of the competition, in 1987, a new sniper rifle was adopted by the US Army under the designation M24 SWS (SWS - "Sniper Weapon System", which translates as "sniper weapon system.").
M24 stainless steel barrel, 610 mm long, specially treated for firing M118 7.62 mm NATO sniper ammunition. The barrel has a Remington-designed 5R drill, which has 5 grooves with rounded edges (to reduce friction). The rifling pitch is 1 turn per 286 mm.
The standard Leupold-Stevens M3 Ultra daytime optical sight has a fixed magnification of 10X, a scale for determining the range and a compensator to take into account the decrease in the trajectory of the bullet.
The weapon is fed from a fixed 5-round magazine.
The M24 polymer stock has a wide bore as the rifle's barrel is almost an exact cone.
The butt plate is adjustable to a length of 69 mm back and forth to suit any shooter.
Bipod – adjustable, folding.
M24
complete with case
The rifle comes in a hard case that contains the rifle, optical and removable diopter sights, bipod, rifle care accessories, binoculars, and spare magazines. The approximate weight of such ammunition is about 20 kg.
In addition to the main version of the M21, batches of M24 rifles in the .300WM caliber were manufactured for the army special forces units (SOCOM) chambered for the .300 Winchester Magnum (.300WM) cartridge (the original modification of the .308 caliber initially provided for this capability).
Remington also produces a modification of the M24 in the form of the M24A2, in which the butt of the rifle received a vertically adjustable cheekpiece, a detachable magazine for 10 rounds, as well as top and side Picatinny-type rails. The M24A2 barrel is primarily designed for use in conjunction with a suppressor.
Since the US Army's adoption of the M24, it has become the standard against which all other military-grade sniper rifles are judged.
The M24 rifle was used by American troops in all local conflicts of the late 20th and early 21st centuries.

Story
By the mid-1980s, the M21 sniper rifles in service, created on the basis of the M14 semi-automatic rifle, began to become inoperative, and the problem of spare parts became acute. In addition, the changed situation in the world has shifted the center of the main possible operations of the US Army from Europe to the Near and Middle East. Open desert spaces dictated the requirements for accurate shooting at distances of up to 1000 meters. Not without an eye on the US Marine Corps, the Army created requirements for a new rifle, which was supposed to have a longitudinally sliding bolt, a polymer stock and a stainless steel barrel. As a result of the competition, Steyr SSG69 and Remington Model 700BDL were in the finals. Remington won, and in 1987 the M24 rifle was adopted by the US Army.

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.“Andrei Sevastyanich,” said Rostov, “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, 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 screeched 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.”
