M240 Family of Medium Machine Guns - FN Manufacturing, LLC

Information
The M240 was adopted by the U.S. Military following a world-wide competition for a reliable 7.62 mm machine gun for use as a coaxial weapon for armored vehicle applications. The Coaxial version of the famous Belgian MAG 58, produced by FN Herstal, won this competition. The demonstrated reliability of this weapon, 26,000 Mean Rounds Between Failure (MRBF), makes it the world's most reliable machine gun. As a result of the outstanding performance of this weapon, vehicle, aviation, and infantry variants are now in use by the U. S. Military. The US variants are produced by FN Manufacturing, a US subsidiary of FN Herstal S.A.

Interoperability
The U. S. produced M240 variants are produced to the exacting specifications of the original MAG 58. consequently, all M240 variants have interchangeable components and are interoperable with foreign-produced NATO equivalent weapons. This has significant advantages in training, logistics support, and tactical versatility. For example, an M240B buttstock and bipod may be carried in an armored vehicle to enable the tank crew to convert the coaxial weapon to an infantry model in the event that they are forced to dismount from a vehicle.
