The Modular Sniper Rifle, or MSR, is a bolt-action sniper rifle recently 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. The MSR won the PSR competition, and is called the Remington Precision Sniper Rifle in U.S. military service.
On 7 March 2013, MSR was declared the winner the Precision Sniper Rifle competition. Remington announced that the MSR had won on March 8, and it was publically 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. 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 Incorperated.
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 receiver also is fitted with monolithic Picatinny rail used to install sighting equipment (telescope sights or night vision sights). Additional equipment includes 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 g) .338 Lapua Magnum ammunition.
Changes to the PSR version include:
- Reinforced AAC muzzle brake for Titan QD suppressor
- Chromoly steel .338 barrel with 1:9.5 twist, 5R rifling, and Melonite (ferritic nitrocarburized) finish
- One piece handguard with 20 MOA top rail
- Barrel nut accessible without removing the handguard
- X-treme trigger
- Light weight, removable buttstock with throw lever adjustments instead of ratcheting adjustments
- United States: USSOCOM, winner of the Precision Sniper Rifle competition.
- Colombia: Colombian Special Forces.
