XM250

The M250, previously the XM250, is the U.S. Army's designation for the SIG LMG 6.8, chambered in 6.8×51mm Common Cartridge (.277 Fury), gas-operated, belt-fed light machine gun that features a proprietary recoil mitigation system, designed by SIG Sauer for the U.S. Army as part of the Next Generation Squad Weapon Program in 2022 to replace the M249 Squad Automatic Weapon.
The M250 features a free-floating reinforced M-LOK handguard for direct accessory attachment onto the "negative space" (hollow slot) mounting points. The M250 began to be fielded in March 2024.
