The Precision Sniper Rifle (PSR) was a program by United States Special Operations Command to replace all current bolt-action sniper rifles in use by U.S. special operations snipers with a single bolt-action rifle chambered for a large caliber Magnum chambering like .300 Win Mag, and .338 Lapua Magnum. The solicitation was placed on January 15, 2009. The contract was awarded to Remington Arms for their Modular Sniper Rifle.
