Design & History
Manufactured by Fabrique Nationale subsidiary FN Manufacturing, Inc. Columbia, SC, the M240 was chosen by the US military after a world-wide search for a weapon to replace the venerable M60. While possessing many of the same basic characteristics as its predecessor, the durability of the M240 system results in superior reliability and maintainability when compared to the M60. Compared to other machineguns, its rating of 26,000 Mean Rounds Between Failure (MRBF), makes it the world's most reliable machine gun. The M240 is a left hand feed, gas operated, air cooled, fixed head space weapon. Its functionality is demonstrated by its ability to be mounted on the M122A1 tripod, a bipod, on vehicles, or on Aircraft.
Variations
The NATO version of the M240 is known as the MAG 58. The U.S. produced M240 family is produced to the same exacting specifications of the MAG 58 enabling all M240 variants to have interchangeable, interoperable components with foreign-produced NATO equivalent weapons. This has significant advantages in training, logistics support, tactical versatility, and joint operations. For example, an M240B buttstock and bipod may be carried in an vehicle to enable the crew to convert the coaxial weapon to an infantry model in the event that they are forced to withdraw from a non-operable vehicle.
M240B
The M240B is the standard infantry medium Machine gun of the US Army. It comes configured in for ground combat.
M240G
A similar version of the M240, the M240G, is the standard US Marine Corps medium machine gun. The Marine Corps is replacing the M60E3 with the M240G. The M240 allows for commonality throughout the Marine Corps whether the weapon is used in an infantry, vehicular, or airborne role. The M240G is the ground version of the original M240/M240E1, 7.62 mm medium class weapon designed as a coaxial/pintle mounted machine gun for Tanks and Light armored vehicles (LAVs). The M240G can be modified for ground use by the installation of an "infantry modification kit," (a flash suppressor, front sight, carrying handle for the barrel, a buttstock, infantry length pistol grip, M249
