The Remington Defense "Modular Sniper Rifle" - or "MSR" - was drawn up in 2009 to compete for a new armor-defeating Special Operations COMmand (SOCOM) infantry sniper rifle requirement under the "Precision Sniper Rifle" (PSR) competition. The goal of the competition was to succeed all in-service SOCOM Magnum-firing bolt-action sniper weapon systems to which the Remington MSR was declared the winner over the competing Finnish Sako TRG M10 model in March of 2013. This then cleared the path for formal service introduction to occur before the end of that year.

In the U.S. Army / SOCOM inventory, the rifle is designated Mk 21 "Precision Sniper Rifle".

The MSR has all the elements of a modern sniping platform including Picatinny rail support (top, sides, underside) to host a plethora of tactical accessories. It sports a perforated handguard and cushioned / adjustable cheekpiece and shoulder stock sections as well as a solid / adjustable trigger unit, etched pistol grip handle, detachable bipod support, and muzzle brake/quick-detachable suppressor support. The shoulder stock is hinged to fold over the receiver for when on-the-march, keeping the weapon's overall length to a minimum.

The MSR makes use of the tried-and-proven manually-actuated bolt-action system (with a rotary-locked bolt unit) that involves user management of a bolt lever handle found along the rifle's left side. This cycling process is used to eject/clear a spent shell casing from the chamber while, in the same action, introduce a fresh cartridge made ready-to-fire from the detachable box magazine inserted into the magazine well.

The rifle can be chambered (user-configured as needed) for a variety of proven rifle cartridge types including .338 Lapua Magnum, .338 Norma Magnum, .300 Winchester Magnum, and 7.62x51mm NATO. These are fed from a spring-loaded 5-, 7-, or 10-round count magazine (ammunition counts depend on cartridge used and chambering selected). Muzzle velocity reaches up to 3,300 feet-per-second depending on cartridge in play and effective ranges are out to 1,640 yards. Sighting can be had through a variety of supported scopes mounted over the receiver including the Leupold & Stevens Mark 4 and Schmidt & Bender 5-25x56 series.

Relatively lightweight with low maintenance requirements and highly-precise, the Remington MSR represents the future of SOCOM sniping efforts across the modern battlefield.
