M240

U.S. M240 (NSN-1005-01-025-8095)
NATO Equivalent - MAG 58 Coaxial
The U.S. M240 is the standard coaxial weapon for all U. S. armored vehicles and is found on the M1 and M60 tanks as well as the USMC Light Armored Vehicle (LAV) and AAAV.

Interoperability
The U. S. produced M240 family retains all infantry related features and is produced to the same 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 withdraw from a disabled vehicle.
