The U.S. Army's Next Shortest Lived Service Rifle? MCX Spear
The Sig MCX Spear (XM7) is the US Army's new service rifle, chambered in the powerful 6.8x51mm (.277 Fury) cartridge, aiming to replace the M4. While it offers increased firepower, the review highlights significant drawbacks like front-heavy balance, a thick barrel profile, and slower controllability during rapid fire compared to intermediate cartridge rifles. The NGSW program also includes the XM157 optic and XM250 automatic rifle, which may be more impactful than the rifle itself.
