Sniper rifle Remington MSR - Modular Sniper Rifle (USA)

Type of sniper rifle

Modular sniper rifle

, or
MSR
, is a bolt action sniper rifle designed and manufactured by Remington Arms for the United States Army.
It was introduced in 2009 and was designed to meet the specific requirements of the US Army and the USSOCOM Precision Sniper Rifle. [2] The MSR originally won the PSR competition and was referred to as
the Remington
Mk 21
Precision Sniper Rifle . [3] [4] However, it was then decided that the Mk 21 did not meet SOCOM requirements at the time in 2022, and the program was re-competed with the Barrett MRAD, selected in 2022 as the Mk 22 Advanced Sniper Rifle solution. [5]

History[edit]

On March 7, 2013, MSR was announced as the winner of the Precision Sniper Rifle competition. Remington announced that MSR had won on March 8th, and this was publicly confirmed on March 9th. This was followed by a $79.7 million contract for 5,150 suppressed rifles and 4,696,800 rounds of ammunition over the next ten years. [6] [7] The contract was awarded on September 12, 2013. Remington Defense makes sniper rifles and uses two other companies for other system components, with Barnes Bullets for ammunition and Advanced Armament Corporation for muzzle brakes and suppressors; all three companies are subsidiaries of Freedom Group Incorporated. [8]

In 2015, the US Army is considering the PSR to replace both the .300 Winchester Magnum M2010 Enhanced Sniper Rifle and the .50 BMG M107 Long Range Sniper Rifle for regular snipers, although no decision has been made. [9] The United States Marine Corps also considered the Mk 21 to replace its M40A5 sniper rifle, [10] but is unlikely to field the Mk 21 due to the higher cost of the system, especially ammunition, compared to the 7.62mm rifle. NATO M40A5. [eleven]

Excerpt describing Remington MSR

“No, you didn’t understand me,” said the mother, not knowing how to justify herself. “You didn’t understand me, Nikolinka.” “I wish your happiness,” she added and felt that she was telling a lie, that she was confused. - She cried. “Mama, don’t cry, just tell me that you want this, and you know that I will give my whole life, everything, so that you can be calm,” said Nikolai. I will sacrifice everything for you, even my feelings. But that’s not how the Countess wanted to pose the question: she didn’t want a sacrifice from her son, she herself would like to sacrifice to him. “No, you didn’t understand me, we won’t talk,” she said, wiping away her tears. “Yes, maybe I love the poor girl,” Nikolai said to himself, well, should I sacrifice my feelings and honor for my fortune? I’m surprised how my mother could tell me this. Because Sonya is poor, I cannot love her, he thought, “I cannot respond to her faithful, devoted love. And I’ll probably be happier with her than with some Julie doll. I can always sacrifice my feelings for the good of my family, he told himself, but I cannot command my feelings. If I love Sonya, then my feeling is stronger and higher than anything else for me.” Nikolai did not go to Moscow, the countess did not resume conversation with him about marriage, and with sadness, and sometimes even embitterment, she saw signs of greater and greater rapprochement between her son and the dowryless Sonya. She reproached herself for this, but could not help but grumble and find fault with Sonya, often stopping her for no reason, calling her “you” and “my dear.” Most of all, the good countess was angry with Sonya because this poor, dark-eyed niece was so meek, so kind, so devotedly grateful to her benefactors, and so faithfully, invariably, selflessly in love with Nicholas, that it was impossible to reproach her for anything. . Nikolai spent his vacation with his relatives. A fourth letter was received from Prince Andrei's fiancé, from Rome, in which he wrote that he would have long been on his way to Russia if his wound had not unexpectedly opened in a warm climate, which forces him to postpone his departure until the beginning of next year . Natasha was just as in love with her fiancé, just as calmed by this love and just as receptive to all the joys of life; but at the end of the fourth month of separation from him, moments of sadness began to come over her, against which she could not fight. She felt sorry for herself, it was a pity that she had wasted all this time for nothing, for no one, during which she felt so capable of loving and being loved. It was sad in the Rostovs' house. Christmastide came, and besides the ceremonial mass, except for the solemn and boring congratulations of neighbors and courtyards, except for everyone wearing new dresses, there was nothing special to commemorate Christmastide, and in the windless 20-degree frost, in the bright blinding sun during the day and in the starry winter light at night, I felt the need for some kind of commemoration of this time.

Design[edit]

The Remington MSR is a manually operated bolt action firearm. To facilitate changing calibers, the bolt is equipped with removable bolt heads with bolt ends selected for the appropriate calibers. The bolt heads have three radial locking lugs. The MSR is built on an aluminum alloy "chassis" that houses a compact receiver, adjustable trigger, pistol grip and fully adjustable side-folding stock. The quick-change barrels float freely inside the tubular handguard, which is equipped with a number of user-installable optional Picatinny rails. The top of the receiver also features a monolithic Picatinny rail for mounting sighting equipment (optical sights or night sights). Additional equipment includes a removable folding bipod and a quick-release suppressor that mounts over a specially designed muzzle brake.

The PSR competition winning model is a modified version of the original MSR. It can be chambered in 7.62×51mm NATO, .300 Winchester Magnum and .338 Lapua Magnum. It is reported to have an average accuracy of 0.7 MOA at 1,000 m (1,094 yd) with Barnes and ATK 300 gr (19.4 g) .338 Lapua Magnum ammunition. [6]

Changes in the PSR version include: [6]

• Reinforced AAC muzzle brake for Titan QD suppressor [12]
• .338 chrome-moly steel barrel with 1:9.5 twist, 5R rifling and melonite (ferritic nitrocarburizing)
• One-piece handguard with 20 MOA top rail
• Access to the barrel nut without removing the forend
• X-treme trigger
• Lightweight removable stock with travel lever adjustment instead of ratchet adjustment

On 14 August 2014, the Army announced that it was seeking sources to produce .338 Lapua armor-piercing (AP) ammunition for use in the Mk 21 PSR to effectively engage targets out to 1,500 m (1,640 yd). The rifle's primary purpose is to defeat Level IV body armor at a range of 400 meters, both suppressed and unsuppressed, in a temperature range of -65 to 160 °F (-54 to 71 °C). Other minimum requirements include a projectile velocity of 1,340 ft/s (410 m/s) or more at 1,250 m (1,367 yd), kinetic energy of 1,000 ft lb (1,356 J) at 1,500 m (1,640 yd), and the ability to defeat as 3 ⁄8 in (9.5 mm) rolled homogeneous armor (RHA) and 1 ⁄2 in (12.7 mm) cast iron at 800 m (875 yd).[4]

A Remington 700 action fitted into an Accuracy International Chassis System is another configuration popular in recent film and television production. This configuration is often mistaken for a variant of the Accuracy International Arctic Warfare series, but often can correctly be identified by the Remington 700's distinctive bolt action. There are three models of the AICS: the base 1.0 model, the 1.5 which adds an adjustable cheek rest, and the 2.0 which has a folding stock and adjustable cheek rest. Accuracy international also manufactures the AXAICS chassis which emulates the look of the Accuracy International AX rifle series. Two versions of the AXAICS exist, a pre-2014 with a solid stock that folds to the left side of the gun, and a post-2014 model with a skeletonized stock that folds along the right side (with the skeletonised portion accommodating the bolt handle ).

Practice

First, let's try out the Remington 700 SPS Tactical AAC-SD with a 20" barrel. It is interesting to know how the rifle works in its original Hogue stock, because it has aluminum mounting bushings, that is, the so-called pillar bedding. Perhaps she is still able to show a decent result?

Unfortunately, a miracle does not happen: after we shot with grief at the target at 100 m, constant gaps stretch groups of 5 shots to 2-2.5 MOA, which is completely unacceptable for our high-precision standards. It’s not a Kalashnikov assault rifle, but it should shoot more accurately!

It must also be said that without muzzle devices, even a 20-inch carbine “kicks” noticeably and sounds quite loud. Of course, we immediately try to install the Ase Utra SL7 moderator. And although it becomes much more comfortable to shoot with it, we predictably run into the same problem with the stock: if earlier in groups we observed predominantly horizontal breaks, then with the moderator they became vertical. This is because when the gun is fired, the barrel touches the fore-end. In general, the essence is clear - we change the stock.

After switching to the Magpul Hunter stock, the average accuracy improved slightly, but most importantly, the very terrible separations disappeared. However, something still does not allow the rifle to show the result for which it was purchased! Well, let's try with a moderator; Moreover, without it, the short carbine noticeably “goats” on the bipod with each shot.

Installing the Ase Utra SL7 moderator on the carbine in the Magpul Hunter stock finally leads to the desired result: accuracy is reduced to 0.7-1 MOA. Great, let's now test a short carbine with a 16-inch barrel. Impatience and the high cost of renting a shooting station do not allow us to fully shoot a short carbine in its original stock, but after “changing clothes” and the mandatory installation of a moderator, things quickly go smoothly. Its accuracy, as expected, is very similar, and as for the muzzle velocity, according to our measurements, from a 16-inch barrel it was on average 40 m/s less than from a 20-inch barrel. And that, in turn, is another 40 m/s less than from a 26-inch one. Everything is expected, as predicted.

But it’s not worth shooting from a short carbine without a moderator: the volume of the shot, even with shooting headphones, is not for the faint of heart. But how compact and convenient the system of a 16-inch barrel with a moderator is - that’s something!

Accessories

So, we stocked up on Magpul Hunter stock, Harris bipods, Hornady BTHP Match cartridges with a 168-grain bullet, and we seem to be ready to go to the shooting range. But before this, it is necessary to install Picatinny bases on the rifles for mounting optics, and their choice is also not an easy matter. In our opinion, the best solid bases are made for the Remington 700 by the American company Nightforce - they are made of steel, very accurate, have a special recoil claw for gripping the receiver (and reducing the load on the mounting screws) and have a preliminary tilt of 20 or 40 MOA. But, unfortunately, their cost is beyond our budget. A simpler and more affordable alternative is Warne products. These bases are also solid, steel, can be produced with a preliminary tilt, but are slightly simpler in design (in particular, without a recoil paw). Warne bases have also proven themselves well. We take them.

We still have the scope from a previous project - Nikko Stirling Diamong Long Range 6-24×50 on Warne rings. Although, of course, the Remington 700 deserves a more serious scope - for example, such as the Nightforce SHV 5-20x56. The sight and mount should be upgraded at the first opportunity.

And you need one more accessory, without which staying at the shooting range risks not being very comfortable. Shooting from rifles of .308 Win caliber is never completely silent, and even from short and very short barrels, an unexpected shot can seem cleaner than a cannon shot. Even with hearing protection, shooting at an indoor shooting range with such weapons will not be the most pleasant. Therefore, we definitely take with us the SL7 sound moderator from the Finnish company Ase Utra, which has already proven itself well for high-precision tasks. But don’t forget active headphones. And with all this we go to shoot.

Remington 700 carbine

The Remington 700 SPS (Special Purpose Synthetic) is an excellent hunting rifle that is known to many not only because of its name. This model has a barrel and bolt part made of chrome-molybdenum steel.

The butt has a rubber shock absorber, and the stock itself is made of black injection molded polymer. The store is built, with a lid that folds down.

The stock of the 700 SPS model is made of synthetic, which, in fact, ensures reliability and durability. On the neck of the stock and forend you will find inserts made of Hogue's proprietary ergonomic material for a more secure grip on the carbine.

Confident shot distance

Interchangeable magazines are a desirable attribute of a tactical rifle (and one of the advantages of the Magpul Hunter stock)

So, a classic Sierra MatchKing bullet weighing 168 grains, fired at a speed of 825 m/s, is capable of flying about 950 m before friction with the air slows it down to the so-called transonic transition, during which the supersonic speed of the bullet becomes subsonic. At this moment (and it begins at a speed of approximately 350 m/s), the air environment affects the bullet less predictably than at supersonic or subsonic levels. Roughly speaking, the bullet begins to shake in flight, like on a washboard! As a result, it is no longer possible to accurately predict its future flight. Therefore, it is customary to limit the distance of a confident, predictable shot from a rifle to the distance that the bullet covers at supersonic speed - that is, while its speed is still exceeding 350 m/s. Of course, the bullet is capable of continuing its deadly flight further, and for another good 1-3 km - at least if it does not fall to the ground. But it will be difficult for the shooter to hit the target at a greater distance. In any case, it will not be possible to do this consistently and over and over again.

To mount a Harris bipod, you need to add a swivel with an M-Lok interface to the forend.

Now let’s use the calculator to calculate at what distance the transonic barrier is for the same bullet and under the same conditions, but fired from a very short barrel and therefore at a speed of only 750 m/s. This will be a distance of 850 m - a very respectable distance for the .308 Win, I must say! Thus, by shortening the rifle barrel by 40% from 71 cm to 42 cm, we reduced the maximum distance for a confident shot from 950 to 850 m - by only 100 m. Is this a lot or not? Judge for yourself. However, in our experience, 99.9% of shots from the .308 Win are fired at targets located at distances noticeably closer than 700-800 m.
