The Precision Sniper Rifle (PSR) was a program by United States Special Operations Command to replace all bolt-action sniper rifles in use by United States special operations snipers with a single bolt-action rifle chambered for a large caliber Magnum round such as .300 Win Mag and .338 Lapua Magnum. 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.

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 modern sniper rifle is a portable shoulder-fired rifle with either a bolt action or semi-automatic action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance centerfire cartridge.
The bolt-action 7.62×51mm M24 Sniper Weapon System is capable of 0.5 MOA accuracy to maximal effective range of about 800 meters. The M24 was the United States Army standard-issue sniper rifle from 1988 to 2010.
