The M107 anti-material rifle has been adopted by the US Army and is similar to the US Marine Corps Barrett M82A1 .50 caliber sniper system. The M107 enables Army snipers to accurately engage material targets (and personnel in extreme circumsances) out to a distance of 1500 to 2000 meters. The weapon is designed to effectively engage and defeat materiel targets such as aircraft (parked), communications targets, computers, intelligence sites, radar sites, ammunition depots, oil stores as well as lightly armored vehicles.
In a counter-sniper role, the M107 system offers long-range standoff distances and increased terminal effect against snipers using smaller caliber weapons. The complete system includes the rifle itself, a detachable ten-round box magazine, a variable-power day optical sight, a hard transport case, a tactical soft case, cleaning and maintenance equipment, a detachable sling, an adjustable bipod and operator/maintenance manuals. The Army plans to modify future M107s with the addition of a suppressor to greatly reduce flash, noise and blast signatures. The standard M107 is fielded with the Leupold 4.5x14 Vari-X scope.
The weapon is more formally known in its long-form guise as the "Long Range Sniper Rifle, Caliber .50, M107".
