On April 19, 2022, the U.S. Army awarded Sig Sauer a 10-year contract to produce the XM7 and XM250 light machine guns, replacing the M4 and M249, respectively.
The XM7 was originally named XM5, but in January 2023, the Army renamed it XM7 to avoid trademark disputes. The first batch of 25 XM7s will be delivered to the Army by the end of 2023, with plans to procure 107,000 rifles to equip frontline combat units.
