Each M40 is built from a Remington Model 700 bolt-action rifle, and is modified by USMC armorers at Marine Corps Base Quantico, using components from a number of suppliers.<ref name="Senich88"/> New M40A5s are being built, and A1s are upgraded to A3s and A5s as they rotate into the armory for service and repair. The rifles have had many sub-variations in telescopic sights, and smaller user modifications. The M40A5 incorporates a detachable magazine and a threaded barrel to allow for the use of a sound suppressor or another muzzle device.

The original M40 was a military type-classified version of the Remington 700; it was factory-made, and had a one-piece wooden stock.<ref name="Senich88"/> The M40A1 and A3 switched to fiberglass stocks made by McMillan, with new scopes.<ref name="Senich88"/><ref name="USMCSSA">{{cite web|title=M40A3 Sniper Rifle |work=M40A3 |publisher=United States Marine Corps Scout Sniper Association |url=http://www.usmcscoutsniper.org/hogsden/the-m40a3.htm |access-date=23 May 2009 |url-status=dead |archive-url=https://web.archive.org/web/20090622131913/http://www.usmcscoutsniper.org/hogsden/the-m40a3.htm |archive-date=22 June 2009 |df=dmy }}</ref> The trigger pull on both models (M40A1/A3) is {{convert|3|to(-)|5|lb|kg|abbr=on}}.<ref name="Senich88"/>

==History== 300px|left|thumb|The M40A3

During the Vietnam War, the Marine Corps decided they needed a standard sniper rifle.<ref name="Senich88"/> 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.<ref name="Senich88"/> Most had a Redfield 3–9x Accurange variable scope mounted. With time, certain weaknesses, primarily warping of the all-wood stock, became apparent.<ref name="Senich88"/>

Sometime in the early 1970s, the USMC armorers at MCB Quantico began rebuilding the original M40s into M40A1s.<ref name="Senich88"/> 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.<ref name="Senich88"/> The M40 was originally designed by Jack Cuddy and Gunner/Captain/CW04 Neil Warren Goddard.<ref name="Senich88"/> The stock featured Wichita sling swivels and a Pachmayr buttpad.<ref name="Senich88"/>

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.<ref>{{cite web|url=http://www.marinecorpstimes.com/news/2011/03/marine-corps-sniper-rifle-m110-031711w/|title=Corps fielding new semi-automatic sniper rifle|last=Lamothe|first=Dan|date=17 March 2011|publisher=Marine Corps Times|access-date=18 March 2011|url-status=dead|archive-url=https://web.archive.org/web/20110714034725/http://www.marinecorpstimes.com/news/2011/03/marine-corps-sniper-rifle-m110-031711w/|archive-date=14 July 2011|df=dmy-all}}</ref><ref name="debate rage">{{cite web|first=James K.|last=Sanborn|url=https://www.marinecorpstimes.com/news/your-marine-corps/2015/06/17/debate-rages-over-the-need-for-a-better-marine-sniper-rifle/|publisher=Marine Corps Times|date=17 June 2015|title=Debate rages over the need for a better Marine sniper rifle |archive-url=https://web.archive.org/web/20211118232746/https://www.marinecorpstimes.com/news/your-marine-corps/2015/06/17/debate-rages-over-the-need-for-a-better-marine-sniper-rifle/ |archive-date=18 November 2021}}</ref> 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.<ref name="unlikely get more powerful sniper2015">{{cite web |last=Cox |first=Matthew |title=More Powerful, Special-Ops Sniper Rifle Unlikely for Marine Snipers |url=https://www.military.com/daily-news/2015/07/30/more-powerful-special-ops-sniper-rifle-unlikely-marine-snipers.html |website=Military.com |access-date=25 June 2022 |archive-url=https://web.archive.org/web/20201025000946/https://www.military.com/daily-news/2015/07/30/more-powerful-special-ops-sniper-rifle-unlikely-marine-snipers.html |archive-date=25 October 2020 |date=30 July 2015}}</ref>

In April 2018, 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.<ref name="marinecorpstimes2april18"/>

==Variants== ===M40A3=== Development of the M40A3 began in 1996 and concluded in 2001,<ref name="USMCSSA"/> 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.

'''Action''': The M40 has always been based on the Remington 700 Short Action with .308 bolt face, and this is no different in the M40A3.<ref name="Janes"/> These actions are tuned by Marine armorers; the M40A1 trigger guard and floor plate was assembly manufactured by Winchester using the model 70 steel which was cut about one inch to fit the Remington 700 action and McMillan camo stock. DD Ross Company, though several M40A3s use Badger Ordnance trigger guards.<ref name="USMCSSA"/> In 2007, the Marine Corps began replacing the DD Ross trigger guard assemblies with the M5 detachable magazine trigger guard manufactured by Badger Ordnance.<ref name="Janes"/>

'''Barrel''': The barrel on the M40A1 was made by Bill Atkinson, this barrel is 24" long made from 416 stainless steel, bead blasted and blued with black oxide. M40A3 is a Schneider 635; 25-inch, 6-groove, 1:12" match-grade heavy barrel.<ref name="Janes">{{cite web | title = M40A3 7.62 mm sniper rifle (United States), Sniper and special purpose rifles | work = Jane's Infantry Weapons | publisher = Jane's| url = http://www.janes.com/extracts/extract/jiw/jiw_9094.html| access-date = 23 May 2009}} {{Dead link|date=September 2010|bot=H3llBot}}</ref><ref name="M40A3"/>

'''Stock''': All service M40A3s are based upon the A4 Tactical Riflestock, a benchrest-style fiberglass riflestock made by McMillan Fiberglass Stocks and cast molded in an OD Green color.<ref name="USMCSSA"/><ref name="M40A3"/> The action is glass bedded into the stock with aluminum pillars, while the barrel is allowed to "float" (it is attached only to the action), ensuring it is stress free during operation. The stock has adjustable length-of-pull (through a buttstock spacer system) and a Marine manufactured adjustable saddle-type cheekpiece.<ref name="M40A3"/> The stock also has six flush mount sling swivel cups, two on each side front and back and one each on the front and rear underside.<ref name="USMCSSA"/> One bipod stud is located on the underside of the forend.<ref name="M40A3">{{cite web|title=WTBN, MCB, CLNC, M40A3 Sniper Rifle |work=USMC Fact File |publisher=Marine Corps Base, Camp Lejeune |url=http://www.lejeune.usmc.mil/wtbn/wtbn_mcb_clnc_m40a3_sniper_rifle.htm |access-date=23 May 2009 |url-status=dead |archive-url=https://web.archive.org/web/20080917175809/http://www.lejeune.usmc.mil/wtbn/wtbn_mcb_clnc_m40a3_sniper_rifle.htm |archive-date=17 September 2008 |df=dmy }}</ref>

'''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.

[[File:Scout sniper snow MARPAT.jpg|thumb|Snipers utilize an M40A5 with bipod and suppressor while training at the Mountain Warfare Training Center]] '''Bipod''': The M40A3s use a 6–9" Harris notched swivel type bipod, model S-BRM, with a KMW Pod-Loc, which is a push button ratcheting bipod swivel locking mechanism.<ref name="M40A3"/>

'''Dayscope''': The M8541 Scout Sniper Day Scope is a Schmidt and Bender Police Marksman II LP 3–12×50 modified by Premier Reticles.<ref name="reticles">{{cite web |title=Contract M67854-05-D-1043 |url=http://www.marcorsyscom.marines.mil/Portals/105/Counsel/Contracts/M67854-05-D-1043~Premier%20Reticles.pdf |website=Marine Corps Systems Command |access-date=25 June 2022 |archive-url=https://web.archive.org/web/20140113001634/http://www.marcorsyscom.marines.mil/Portals/105/Counsel/Contracts/M67854-05-D-1043~Premier%20Reticles.pdf |archive-date=13 January 2014 |date=5 August 2005}}</ref> Starting in 2007, this model replaced the Unertl MST-100 10× fixed day scope.<ref name="M40A3"/> This dayscope is mounted with Badger Ordnance USMC M40A3 34mm scope rings, which use a standard ring in the rear and a wider MAX-50 ring in front.<ref name="USMCSSA"/> The standard front ring cap is replaced with a SPA-Defense B634 34mm Male Dovetail, as 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.<ref name="USMCSSA"/><ref name="Janes"/>

===M40A5=== The M40A5 superseded the M40A3 in 2009, though the evolution between the two systems occurred gradually over a longer period. The primary difference between the M40A5 and the M40A3 is the barrel: The A3's target crown has been replaced with a threaded muzzle and straight tapered barrel allowing the installation of a Surefire muzzle brake and sound suppressor.<ref name="m40a5 2009 updates">{{cite web |last1=Gourley |first1=Scott R. |title=Marine Corps Seeks M40A5 Sniper Rifle Support |url=https://www.defensemedianetwork.com/stories/marine-corps-seeks-m40a5-sniper-rifle-support/ |website=Defense Media Network |access-date=25 June 2022 |archive-url=https://web.archive.org/web/20110917215655/http://www.defensemedianetwork.com/stories/marine-corps-seeks-m40a5-sniper-rifle-support/ |archive-date=17 September 2011 |date=21 July 2009}}</ref> All M40A5s are fitted with a Badger Ordnance detachable magazine system and a forward rail mount for the AN/PVS-22 night vision optic.<ref name="LN"/>

===M40A6/A7=== thumb|M40A6

On 25 July 2013, the Marine Corps released a solicitation for the M40 Modular Stock Program. Upgraded features are to include a folding stock, compatible with current M40 actions and barrels, to make the rifle more compact for transportation inside confined spaces like vehicles and a full-length rail to accommodate optics and accessories; the M40A5 has only a few inches of rail space beyond the scope for a night vision optic, so extending the rail length would allow more accessories to be attached, enabling snipers to put rounds on target under any conditions. Deliveries were to begin three months after the contract being awarded, with 1,100 stocks to be purchased to upgrade the entire M40A5 inventory. The resulting weapon from the program was originally to be re-designated the M40A6.<ref name="corps seeks modular">{{cite web |last=Sanborn |first=James K. |url=http://www.marinecorpstimes.com/article/20130811/NEWS04/308110005/Corps-seeks-modular-stock-sniper-rifle |title=Corps seeks modular stock for sniper rifle |website=Marine Corps Times |date= 11 August 2013 |archive-url=https://web.archive.org/web/20140203054315/http://www.marinecorpstimes.com/article/20130811/NEWS04/308110005/Corps-seeks-modular-stock-sniper-rifle |archive-date=3 February 2014}}</ref> Remington was awarded the contract in November 2014.<ref name="remington contract 2014">{{cite web |last1=R |first1=Tom |title=Remington Awarded Contract for the Marine's M40 Sniper Rifle Program |url=https://www.thefirearmblog.com/blog/2014/11/07/remington-awarded-contract-marines-m40-sniper-rifle-program/ |website=The Firearm Blog |access-date=25 June 2022 |archive-url=https://web.archive.org/web/20210121083024/https://www.thefirearmblog.com/blog/2014/11/07/remington-awarded-contract-marines-m40-sniper-rifle-program/ |archive-date=21 January 2021 |date=7 November 2014}}</ref> The final product will be designated the '''M40A7''' and was planned to be fielded by 2017.<ref name="SSD m40a6">{{cite web |title=Sneak Peek – USMC M40A6 Prototype |url=https://soldiersystems.net/2015/03/16/sneak-peek-usmc-m40a6-prototype/ |website=Soldier Systems Daily |access-date=25 June 2022 |archive-url=https://web.archive.org/web/20220528030852/https://soldiersystems.net/2015/03/16/sneak-peek-usmc-m40a6-prototype/ |archive-date=28 May 2022 |date=16 March 2015}}</ref> The M40A6 began fielding with Marine Corps in June 2016.<ref name="aiming higher caliber 2016">{{cite web |last1=Calingo |first1=Ashley |title=AIMING FOR A HIGHER CALIBER: DEVELOPING FUTURE WEAPON SYSTEMS FOR MARINE CORPS SNIPERS |url=https://www.marines.mil/News/News-Display/Article/880321/aiming-for-a-higher-caliber-developing-future-weapon-systems-for-marine-corps-s/ |website=US Marine Corps |publisher=Marine Corps Systems Command |access-date=25 June 2022 |archive-url=https://web.archive.org/web/20201208002019/https://www.marines.mil/News/News-Display/Article/880321/aiming-for-a-higher-caliber-developing-future-weapon-systems-for-marine-corps-s/ |archive-date=8 December 2020 |date=29 July 2016}}</ref>

==Differences between M40 and M24== The U.S. Army also used the Remington 700/40x action as the basis for its M24 Sniper Weapon System.<ref name="Senich88"/> 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 {{convert|2.750|in|mm|2}} or less (such as the .308 Winchester/7.62×51&nbsp;mm NATO), the Army M24 uses the Remington 700 Long Action.<ref name="Senich88"/> The long action of the M24 is designed for full-length cartridges up to {{convert|3.340|in|mm|2}} 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.<ref name="Senich88"/> 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.<ref>[http://www.snipercentral.com/m24.htm U.S. Army M24 Sniper Weapon System] {{Webarchive|url=https://web.archive.org/web/20061223121521/http://www.snipercentral.com/m24.htm |date=23 December 2006 }}. Snipercentral.com. Retrieved on 6 January 2014.</ref> Despite the fact that the M24 came fitted with a 7.62×51&nbsp;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 {{convert|25|in|mm|0}} Schneider barrel and the U.S. Army M24 used a {{convert|24|in|mm|0}} Rock Creek 5R barrel.
