.308 Winchester/7.62×51 mm NATO), the Army M24 uses the Remington 700 Long Action. The long action of the M24 is designed for full-length cartridges up to in overall length, such as the .30-06 Springfield, and magnum cartridges such as the 7 mm Remington Magnum and .300 Winchester Magnum, but shorter cartridges such as the 7.62×51mm NATO (the military version of the .308 Winchester) can also be used. The U.S. Army's use of the long action was the result of an original intention to chamber the M24 for .30-06 Springfield. Despite the fact that the M24 came fitted with a 7.62×51 mm NATO barrel upon issue, retaining the longer action allowed them to reconfigure the rifle in dimensionally larger cartridge chamberings if necessary (which has been the case during the longer engagement distances during Operation Enduring Freedom). In 2014 the last U.S. Army M24 rifles were reconfigured to M2010 Enhanced Sniper Rifles that are chambered for .300 Winchester Magnum. The barrels not currently fitted to the rifles are usually stored with the unit armorers. The U.S. Marine Corps M40A3 uses a Schneider barrel and the U.S. Army M24 used a Rock Creek 5R barrel.
