The SIG Sauer MCX Spear is the commercial version of the XM7, the rifle that won the U.S. Army's Next Generation Squad Weapon contract. Chambered in the revolutionary 6.8x51mm (.277 SIG Fury), the MCX Spear delivers unprecedented energy and range from a combat-ready platform.
Features a 16-inch barrel, 20+1 capacity, short-stroke gas piston system, and folding stock. The 6.8x51mm cartridge delivers rifle-caliber performance that exceeds anything previously fielded in a standard infantry weapon, making this one of the most capable semi-automatic rifles available to civilians.
