XM7

The U.S. Army's next-generation high-pressure 6.8 mm rifle, replacing the M4 in close-combat formations with greater range and barrier penetration.

Overview

The XM7 (type-classified as the M7) is a select-fire individual weapon chambered in the 6.8×51 mm Common Cartridge, developed by SIG Sauer under the Next Generation Squad Weapon (NGSW) program. It is a gas-piston operating, suppressor-ready rifle that integrates a dedicated fire-control optic (the XM157) and a signature-suppression system. Fielded from 2024, it replaces the M4A1 carbine in U.S. Army close-combat units, while the U.S. Marine Corps has publicly declined the platform in favour of the 5.56 mm M27.

Development

The U.S. Army launched the NGSW program to provide infantrymen with a round capable of defeating modern body armour at extended ranges, codifying the requirement after two decades of combat in Iraq and Afghanistan. On 19 April 2022, the Army awarded SIG Sauer a 10-year production contract, originally ceilinged at $4.5 billion, to deliver the XM7 rifle and the companion XM250 automatic rifle, as reported by GovConWire. The design was initially designated XM5, but was renamed XM7 to avoid trademark conflict; the first operational unit, 1st Brigade of the 101st Airborne Division, received the weapon in 2024, according to Army Recognition.
