Precision Sniper Rifle

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.

History
A 2008 United States military market survey for a Precision Sniper Rifle (PSR) called for 1 MOA (0.3 mrad) extreme vertical spread for all shots in a 5-round group fired at targets at 300, 600, 900, 1,200 and 1,500 meters.

In 2009 a United States Special Operations Command market survey called for 1 MOA (0.3 mrad) extreme vertical spread for all shots in a 10-round group fired at targets at 300, 600, 900, 1,200 and 1,500 meters. The 2009 Precision Sniper Rifle requirements stated that the PSR when fired without suppressor shall provide a confidence factor of 80% that the weapon and ammunition combination is capable of holding 1 MOA extreme vertical spread. This shall be calculated from 150 ten (10) round groups that were fired unsuppressed. No individual group shall exceed 1.5 MOA (0.5 mrad) extreme vertical spread. All accuracy will be taken at the 1,500 meter point. Other requirements were that the rifle weigh less than 18 pounds loaded, have Picatinny rails, and have an easily-changeable barrel.

Project manager for Soldier weapons Colonel Douglas Tamilio said in April 2011 he expected the Army to select and start fielding a new Precision Sniper Rifle in the next three to four years. The contract was expected to be awarded by March 2013.

Selection
On March 8, 2013, the Remington announced that the Modular Sniper Rifle won the contract, beating out the Sako TRG M10. The contract is worth $79.7 million for 5,150 rifles including suppressors, and 4,696,800 rounds of ammunition over the next ten years.
