The Next Generation Squad Weapon (NGSW) program is a United States military program created in 2017 by the U.S. Army to replace the 5.56mm M4 carbine, the M249 SAW light machine gun, and the 7.62mm M240 machine gun, with a common system of 6.8mm cartridges and to develop small arms fire-control systems for the new weapons. [1] [2]
Seven defense manufacturers competed in the program, with five attempting to design and produce the weapons and two attempting to create and supply fire-control optics. [3] The winners were officially announced by the Army in early 2022: SIG Sauer to produce the XM7 rifle and XM250 automatic rifle, Vortex Optics to produce the XM157 fire-control system, [3] and Winchester to produce the custom 6.8mm ammunition cartridges designed by SIG Sauer. [4] [5] [6] The program was expected to cost $10 million in the first year of production, and $150 million the next. [1] [5] [6]
The NGSW program began in 2017, after the U.S. Congress issued an order for the U.S. Army to conduct an assessment regarding the need to upgrade existing M4 carbines with SOCOM's SOPMOD free-floating rail. It was concluded that the M4 carbine was still favored by troops and also performed well under stress. Feeding issues and other problems were fixed by using different ammunition types and magazines. Despite this, the M4 had difficulty penetrating the types of bulletproof vests used by Russian and Chinese troops, especially at longer ranges.[ citation needed ] Pressure to develop a new weapon system also arose from military programs created by other countries, such as Russia's Ratnik program.[ citation needed ] The U.S. Army's Soldier Enhancement Program released its findings in December 2017, which recommended proceeding with the Next Generation Squad Weapon Program as a more cost-effective solution compared to only retrofitting M4s with free-float rail systems. [7]
Previous attempts to replace the M4 failed due to lack of funding, poor submissions, or re-evaluation of tactics and requirements. [8] [ unreliable source? ] [9] These included the Objective Individual Combat Weapon program, the Special Purpose Individual Weapon program, and the Advanced Combat Rifle program (not to be confused with the Adaptive Combat Rifle).
In 2017, the U.S. Army issued requirements for prototype Next Generation Squad Weapon submissions. [1] [2] [6] The program's rifle requirement, referred to as NGSW-R, was required to use a 6.8mm round and be able to utilize small arms fire-control systems. The program's support weapon, referred to as NGSW-AR, was required to be no longer than 35 in (890 mm); no heavier than 12 lb (5.4 kg) including attachments; able to suppress targets out to 3,900 ft (1,200 m); able to accurately fire on targets out to 2,000 ft (610 m); able to make use of small arms fire-control systems.
On April 19, 2022, after 27 months of prototyping and evaluation, the Army announced that SIG Sauer was awarded the NGSW program contract, and would produce the replacements for the M4 carbine and M249 SAW for the next 10 years. [10] The new rifle, designated the XM7, is based on the company's SIG MCX Spear rifle, while the new automatic rifle, designated the XM250, is based on the company's SIG MG 6.8mm belt-fed gun. [11]
The company was awarded a small initial production order, worth $10.4 million, for about 25 rifles, 15 automatic rifles, and a “large quantity” of ammunition so the weapons could be tested and the production line fine-tuned. [12]
A U.S. Army press release stated the new weapons would "provide significant capability improvements in accuracy, range and overall lethality. They are lightweight, fire more lethal ammunition, mitigate recoil, provide improved barrel performance, and include integrated muzzle sound and flash reduction." [4]

The program also included the development of new fire-control systems for small-arms weapons. Two companies entered the competition: Vortex Optics and L3Harris Technologies, both of whose submissions utilized integrated fire-control systems using laser rangefinders, direct view optics, digital overlays, and ballistic calculation systems, as per NGSW program requirements. [26] In late January 2022, the U.S. Army selected Vortex Optics' offering, designated the XM157 fire-control system. [26] [27]
NGSW weapon proposals used proponent designed cartridges with government-issued 6.8mm general-purpose projectiles. This allowed each proposed weapon and cartridge to be designed together to meet the performance requirements. In January 2022, Winchester was awarded a contract to produce the ammunition. In April 2022, with the selection of the MCX Spear, SIG Sauer's hybrid metal cartridge would become the new cartridge subsequently referred to as 6.8x51mm Common Cartridge by the U.S. Army. [4]
A squad automatic weapon (SAW), also known as a section automatic weapon or light support weapon (LSW), is a man-portable automatic firearm attached to infantry squads or sections as a source of rapid direct firepower. Weapons fulfilling this role can be light machine guns, or modified selective-fire rifles fitted with a heavier barrel, bipod and a belt/drum-fed design.
The M4 carbine is a 5.56×45mm NATO assault rifle developed in the United States during the 1980s. It is a shortened version of the M16A2 assault rifle.
Several sister companies that design and manufacture firearms use the brand name SIG Sauer. The original company, Schweizerische Waggonfabrik (SWF), later Schweizerische Industrie-Gesellschaft (SIG), went through several selloffs, leaving the SIG Sauer brand spread over several companies. The original SIG is now known as SIG Combibloc Group and no longer has any firearms business.
The FNSCAR is a family of gas-operated short-stroke gas piston automatic rifles developed by Belgian manufacturer FN Herstal (FN) in 2004. It is constructed with modularity for the United States Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition. This family of rifles consists of two main types. The SCAR-L, for "light", is chambered in 5.56×45mm NATO and the SCAR-H, for "heavy", is chambered in 7.62×51mm NATO. Both types are available in Close Quarters Combat (CQC), Standard (STD), and Long Barrel (LB) variants.

REC7 is available in either 5.56×45mm NATO or 6.8mm Remington SPC. The REC7 is Barrett's second AR-pattern rifle chambered for the 6.8mm Remington SPC cartridge, the first being the Barrett M468 rifle. The 6.8 SPC-chambered M468 rifle employed the same direct gas-impingement system as the M4.
The SG 550 is an assault rifle manufactured by SIG Sauer AG in Switzerland. "SG" is an abbreviation for Sturmgewehr. The rifle is based on the earlier 5.56×45mm NATO SIG SG 540.
The LSAT light machine gun is a component of the Lightweight Small Arms Technologies (LSAT) program. The purpose of the program was to develop a lighter, yet highly reliable light machine gun (LMG). The program was initiated in 2004, when the Joint Service Small Arms Program (JSSAP) challenged the American defence industry to develop a lighter small arms and also design lighter ammunition.
The M27 Infantry Automatic Rifle (IAR) is a 5.56mm, select-fire assault rifle, based on the HK416 by Heckler & Koch. It is used by the United States Marine Corps (USMC) and is intended to be issued to all infantry riflemen as well as automatic riflemen. The USMC initially planned to purchase 6,500 M27s to replace a portion of the M249 light machine guns employed by automatic riflemen within Infantry and Light Armored Reconnaissance Battalions. Approximately 8,000–10,000 M249s will remain in service with the Marine Corps to be used at the discretion of company commanders. In December 2017, the Marine Corps announced that it would equip every member of an infantry squad with the M27, supplanting the M4 carbine which would be retained at the platoon leadership positions and above.
The M249 SAW, formally the Light Machine Gun, 5.56 mm, M249, is the United States Armed Forces adaptation of the Belgian FN Minimi, a light machine gun manufactured by FN Herstal (FN.)
Polymer-cased ammunition (PCA) is firearm ammunition (cartridge) with casings made from synthetic polymer instead of the typical metallic casing. PCA is considered a new alternative that potentially reduces production cost and weight for long guns and handguns.
