The Modular Sniper Rifle, or MSR, is a bolt-action sniper rifle developed and produced by Remington Arms for the United States Army. It was introduced in 2009, and was designed to meet specific United States Army and USSOCOM Precision Sniper Rifle requirements. [2] The MSR initially won the PSR competition, and was called the Remington Mk 21 Precision Sniper Rifle in U.S. military service. [3] [4] However, it was then decided that the Mk 21 did not conform to SOCOM requirements at the time in 2018, and the program was re-competed with the Barrett MRAD selected in 2019 as the Mk 22 Advanced Sniper Rifle solution. [5]
On 7 March 2013, MSR was declared the winner of the Precision Sniper Rifle competition. Remington announced that the MSR had won on March 8, and it was publicly confirmed on March 9. This was followed by a $79.7 million contract for 5,150 rifles with suppressors, along with 4,696,800 rounds of ammunition to be supplied over the next ten years. [6] [7] The contract was awarded on 12 September 2013. Remington Defense produces the sniper rifles and utilizes 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 U.S. Army was 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 U.S. Marine Corps was also considering the Mk 21 to replace their M40A5 sniper rifle, [10] but is unlikely to adopt the Mk 21 due to the higher cost of the system, particularly the ammunition, as compared to the 7.62mm NATO M40A5. [11]
The Remington MSR is a manually operated bolt-action weapon with a rotary locking bolt. To facilitate caliber change, the bolt is equipped with removable bolt heads, with bolt faces matched for appropriate calibers. Bolt heads have three radial locking lugs. The MSR rifle is built upon an aluminum alloy "chassis", which hosts a compact receiver, adjustable trigger unit, pistol grip, and fully adjustable side-folding buttstock. The quick-change barrels are free-floated inside the tubular handguard which is provided with a number of user-installable Picatinny type accessory rails. The top of the receiver also is fitted with a monolithic Picatinny rail used to install sighting equipment (telescope sights or night vision sights). Additional equipment includes a detachable folding bipod and a quick-detachable suppressor which installs over the specially designed muzzle brake.
The model that won the PSR competition 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 0.7 MOA average accuracy at 1,000 m (1,094 yd) with both Barnes and ATK 300 gr (19.4 g) .338 Lapua Magnum ammunition. [6]
Changes to the PSR version include: [6]
On 14 August 2014, the Army announced 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 main objective is for the rifle to defeat level IV body armor at 400 meters, whether suppressed or unsuppressed, in temperature ranges 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), 1,000 ft⋅lb (1,356 J) of kinetic energy at 1,500 m (1,640 yd), and the ability to defeat both 3⁄8 in (9.5 mm) of rolled homogeneous armor (RHA) and 1⁄2 in (12.7 mm) of cast iron at 800 m (875 yd).

A sniper rifle is a high-precision, long-range rifle. Requirements include high accuracy, reliability, and mobility, concealment, and optics, for anti-personnel, anti-materiel and surveillance uses by military snipers.

The solicitation was placed on January 15, 2009. The contract was awarded to the Remington Modular Sniper Rifle and was designated the Mk 21 Precision Sniper Rifle.
The M2010 Enhanced Sniper Rifle (ESR), formerly known as the XM2010 and M24 Reconfigured Sniper Weapon System, is a bolt action sniper rifle developed by PEO Soldier for the United States Army. It is derived from and replaced the M24 Sniper Weapon System, and was designed to give snipers longer range in the mountainous and desert terrain of the War in Afghanistan. After winning a competitive bidding process, Remington was awarded the production contract for up to 3,600 weapons. The Army had anticipated sending the upgraded weapons to deployed snipers in late 2010, but later expected fielding would happen in January 2011. The M2010 fires .300 Winchester Magnum (7.62×67mm) ammunition, which offers about 50 percent more effective range than the M24's 7.62×51mm NATO. This chambering to dimensionally larger cartridges is possible because the M24 was designed to use the "long action" bolt version of the Remington 700 receiver for cartridges up to 3.34 inches (84.84 mm) in overall length.
The .300 Norma Magnum, also known as .300 NM or 300 Norma, is a centerfire magnum rifle cartridge developed by Swedish ammunition manufacturer Norma Precision.

The MK 13 rifle is made using the Accuracy International Chassis System (AICS) version 2.0 mated to a long action Remington 700 receiver. The AICS 2.0 folding stock reduces the rifle's overall length by 210 mm (8.3 in) when folded and adds 0.2 kg (0.44 lb) to the rifle's total weight. The rifle has a cheekpiece design that adjusts sideways and for height for optimal cheek position when using night vision equipment or telescopic sights with large objective lenses. There is also a quick-adjust cheek-piece option that has a spring-loaded cheek-piece in conjunction with a quick-adjust butt plate. The side panels are made from a high-strength polymer and are available in the colors olive drab, dark earth or black. Sling attachment points are mounted on each side of the rifle, so it can be carried flat against the back and used comfortably by left- and right-handed users. A front attachment point is situated below the fore-end and can be used to anchor a target-style sling or replaced by an adapter for a Harris bipod.
