SIG Sauer Reveals How XM8 Carbine Expands Combat Capabilities for U.S. Army Soldiers

SIG Sauer presented the US Army's XM8, a lighter carbine variant derived from the 6.8 mm M7 rifle, during AUSA in October 2026. The Army's published specifications give an 11-inch barrel and an unloaded weight of 7.3 pounds (approximately 3.31 kilograms). The carbine retains both a conventional rear charging handle and a side charging handle, with shorter dimensions intended to improve handling in confined spaces. The Army approved advancement of XM8 procurement in December 2025 and announced acceptance of its first delivery in April 2026, as part of plans to replace the M4A1 in close-combat formations while complementing the M7.
