The U.S. Marine Corps was also considering the Mk 21 to replace their M40A5 sniper rifle, 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.


Design

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,
