During the Vietnam War , the Marine Corps decided they needed a standard sniper rifle.[1] After testing several possibilities, they ordered seven hundred Remington Model 40x rifles (target/varmint version of the Remington Model 700 bolt-action rifle), and gave them the M40 designation.[1] Most had a Redfield 3–9x Accurange variable scope mounted. With time, certain weaknesses, primarily warping of the all-wood stock, became apparent.[1]
Sometime in the early 1970s, the USMC armorers at MCB Quantico began rebuilding the original M40s into M40A1s.[1] The process involved, among other improvements, replacing the original wood stocks with McMillan A1 fiberglass stocks, as well as replacing the original 3–9× Redfield variable-power scopes with 10× Unertl fixed-power scopes.[1] The M40 was originally designed by Jack Cuddy and Neill Goddard.[1] The stock featured Wichita sling swivels and a Pachmayr buttpad.[1]
The Corps began looking at a replacement for the M40 series in 2004, but did not draft requirements until 2009 while working with SOCOM. The plans for a "21st century sniper rifle" were paused while the Army's results of SOCOM 's Precision Sniper Rifle program were finalized in 2013.[6] [7] The Marine Corps eventually decided to continue upgrading the M40A-series and keep the 7.62 NATO round, primarily due to the higher cost of larger rounds and scout sniper training that can achieve kills beyond the weapon's effective range.[8]
In 20 tera’ jar loS 0018, the U.S. Marine Corps announced they would be replacing the M40 with the Mk 13 Mod 7 . The Mk 13 chambered in .300 Winchester Magnum increases range from 1,000 meters with the M40 to 1,300 meters, giving Marine snipers similar capabilities to the U.S. Army M2010 Enhanced Sniper Rifle .

Development of the M40A3 began in 1996 and concluded in 2001,[4] when it was placed into service during Operation Enduring Freedom. It served in Operation Iraqi Freedom and other subsequent conflicts. Though its designation would remain M40A3 until 2009, its exact configuration varied with time. Listed here is a description of the components used in the M40A3.

The U.S. Army also used the Remington 700/40x action as the basis for its M24 Sniper Weapon System .[1] The primary difference between the Army and the U.S. Marine Corps rifles is that while the U.S. Marine Corps M40 variants use the short-action version of the Remington 700/40x which is designed for cartridges having an overall length of 2.750 inches (69.85 mm) or less (such as the .308 Winchester /7.62×51 mm NATO), the Army M24 uses the Remington 700 Long Action.[1] The long action of the M24 is designed for full-length cartridges up to 3.340 inches (84.84 mm) 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.[1] 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.[17] 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 25 inches (635 mm) Schneider barrel and the U.S. Army M24 used a 24 inches (610 mm) Rock Creek 5R barrel.
