The M40 burglarize is a bolt-activeness sniper rifle used by the United states of america Marine Corps.^[1] It has had four variants: the M40, M40A1, M40A3, and M40A5.^[two] The M40 was introduced in 1966. The changeover to the A1 model was completed in the 1970s, the A3 in the 2000s, and the A5 in 2009.^[3]

Each M40 is congenital from a Remington 700 commodities-action rifle, and is modified by USMC armorers at Marine Corps Base Quantico, using components from a number of suppliers.^[1] New M40A5s are existence congenital, and A1s are upgraded to A3s and A5s every bit they rotate into the armory for service and repair. The rifles take had many sub-variations in scope sights, and smaller user modifications. The M40A5 incorporates a detachable mag and a threaded butt to let for the utilize of a sound suppressor or other muzzle device.

The original M40 was a military type-classified version of the Remington 700; it was mill-fabricated, and had a jumpsuit wooden stock.^[1] The M40A1 and A3 switched to fiberglass stocks made past McMillan, with new scopes.^[ane] ^[iv] The trigger pull on both models (M40A1/A3) is three to 5 lb (one.4–2.3 kg).^[1]

The Marine Corps plans to replace the M40 with the Mk thirteen Mod 7.^[v]

History [edit]

During the Vietnam War, the Marine Corps decided they needed a standard sniper rifle.^[1] Afterward testing several possibilities, they ordered seven hundred Remington Model 40x rifles (target/varmint version of the Model 700 bolt-action rifle), and gave them the M40 designation.^[one] Most had a Redfield 3–9x Accurange variable telescopic mounted. With time, certain weaknesses, primarily warping of the all-wood stock, became apparent.^[i]

Sometime in the early 1970s, the USMC armorers at MCB Quantico began rebuilding the original M40s into M40A1s.^[i] The process involved, among other improvements, replacing the original wood stocks with McMillan A1 fiberglass stocks, as well as replacing the original 3–nine× Redfield variable-power scopes with 10× Unertl fixed-ability scopes.^[i] The M40 was originally designed by Jack Cuddy and Neill Goddard.^[one] The stock featured Wichita sling swivels and a Pachmayr buttpad.^[i]

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 burglarize" were paused while the Army's results of SOCOM'south Precision Sniper Rifle program were finalized in 2013.^[vi] ^[7]

In Apr 2018, the U.Due south. Marine Corps appear they would exist replacing the M40 with the Mk 13 Modernistic 7. The Mk 13 chambered in .300 Winchester Magnum increases range from i,000 meters with the M40 to 1,300 meters, giving Marine snipers similar capabilities to the U.S. Army M2010 Enhanced Sniper Rifle.^[5]

Variants [edit]

M40A3 [edit]

Development of the M40A3 began in 1996 and concluded in 2001,^[iv] when information technology was placed into service during Operation Enduring Liberty. 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.

Action: The M40 has ever been based on the Remington 700 Short Action with .308 bolt face, and this is no dissimilar in the M40A3.^[8] These actions are tuned by Marine armorers; the trigger guard associates is manufactured by the DD Ross Visitor, though several M40A3s utilise Badger Ordnance trigger guards.^[four] In 2007, the Marine Corps began replacing the DD Ross trigger guard assemblies with the M5 detachable magazine trigger guard manufactured by Badger Ordnance.^[eight]

Barrel: The barrel is a Schneider 635; 25-inch, 6-groove, 1:12" match-grade heavy barrel.^[8] ^[9]

Stock: All service M40A3s are based upon the A4 Tactical Riflestock, a benchrest-style fiberglass riflestock fabricated by McMillan Fiberglass Stocks and cast molded in an OD Green color.^[iv] ^[ix] The action is drinking glass bedded into the stock with aluminum pillars, while the butt is immune to "float" (it is attached only to the activeness), ensuring it is stress free during performance. The stock has adaptable length-of-pull (through a buttstock spacer system) and a Marine manufactured adjustable saddle-blazon cheekpiece.^[9] The stock as well has six flush mount sling swivel cups, two on each side front end and back and one each on the front and rear underside.^[iv] One bipod stud is located on the underside of the forend.^[9]

Sling: The Model 1907 sling that has been historically used on M40A3s has been replaced with the Quick Cuff Model Two sling manufactured by Tactical Intervention Specialists.

Bipod: The M40A3s use a half-dozen–9" Harris notched hinge type bipod, model Due south-BRM, with a KMW Pod-Loc, which is a push push ratcheting bipod swivel locking mechanism.^[9]

Dayscope: The M8541 Scout Sniper Twenty-four hours Scope is a Schmidt and Bender Police force Marksman II LP iii–12×l modified past Premier Reticles.^[10] Starting in 2007, this model replaced the Unertl MST-100 10× stock-still day scope.^[9] This dayscope is mounted with Badger Ordnance USMC M40A3 34mm scope rings, which apply a standard ring in the rear and a wider MAX-fifty band in forepart.^[4] The standard front ring cap is replaced with a SPA-Defence force B634 34mm Male person Dovetail, equally a mounting platform for the Simrad KN200 Night Vision Weapon Sight. The scope and rings are mounted on a DD Ross 30-minute-of-angle lugged Picatinny rail.^[four] ^[8]

M40A5 [edit]

The M40A5 designation superseded the M40A3 in 2009, though the development between the two systems occurred gradually over a longer period.^[11] The principal difference betwixt the M40A5 and the M40A3 is the barrel: The A3'south target crown has been replaced with a threaded muzzle and direct tapered barrel to allow the installation of a Surefire cage brake and sound suppressor. All M40A5s are fitted with a Badger Ordnance detachable magazine system and a frontward rail mount for the AN/PVS-22 dark vision optic.^[12]

M40A6/A7 [edit]

On 25 July 2013, the Marine Corps released a solicitation for the M40 Modular Stock Programme. Upgraded features are to include a folding stock, compatible with electric current M40 deportment and barrels, to make the rifle more meaty for transportation inside confined spaces like vehicles and a total-length rail to accommodate optics and accessories; the M40A5 has only a few inches of rails space beyond the telescopic for a night vision optic, so extending the rail length would allow more accessories to exist attached, enabling snipers to put rounds on target nether any atmospheric condition. Deliveries were to brainstorm three months after the contract being awarded, with 1,100 stocks to exist purchased to upgrade the unabridged M40A5 inventory. The resulting weapon from the program was originally to be re-designated the M40A6.^[13] Remington was awarded the contract in Nov 2014.^[14] The final production will exist designated the M40A7 and was planned to exist fielded past 2017.^[15] The M40A6 began fielding with Marine Corps in June 2016.^[16] ^{[ failed verification ]}

Marine scout snipers had pressed for the acquisition of a longer-range sniper rifle to extend date capability. While the M40A5 tin hit targets out to 1,000 meters, they considered the Mk 21 Precision Sniper Rifle chambered in .338 Lapua Magnum used by The states SOCOM that has an effective range of 1,600 meters. Although the Mk 21 has greater range, Marine officials are continuing with upgrading the M40A-series and keeping the seven.62 NATO round, primarily due to the higher cost of larger rounds and scout sniper training that tin can achieve kills beyond the weapon'south effective range.^[17]

Differences between M40 and M24 [edit]

The U.S. Army also used the Remington 700/40x activity every bit the basis for its M24 Sniper Weapon System.^[1] The chief difference between the Regular army and the U.South. 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 two.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 every bit the .30-06 Springfield, and magnum cartridges such as the 7 mm Remington Magnum and .300 Winchester Magnum, simply shorter cartridges such every bit the 7.62×51mm NATO (the military version of the .308 Winchester) can also exist used.^[i] The U.S. Regular army's use of the long action was the event of an original intention to bedchamber the M24 for .thirty-06 Springfield.^[18] Despite the fact that the M24 came fitted with a 7.62×51 mm NATO barrel upon issue, retaining the longer action immune them to reconfigure the rifle in dimensionally larger cartridge chamberings if necessary (which has been the case during the longer date distances during Operation Enduring Freedom). In 2014 the last U.Southward. 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.Southward. Army M24 used a 24 inches (610 mm) Stone Creek 5R barrel.
