The clear winner was the MAG, which was designated as the M in after the army competition. The M was adopted as the U. It then went on to replace many older types of vehicle machine guns in the s. Navy SEALs continued to use the "CAR" M60E3 version of the M60 machine gun due to its lighter weight and slower rate of fire, which allows a more effective duration of fire with allowable levels of ammunition carried. The various versions of the M have not entirely replaced all the M60 versions, though they have for most main applications and roles. The M60 is still, in some cases, used by the Navy.

Gourley While the equipment spotlight for the U. Firing the same 7. According to Zienowicz, Army plans had originally called for replacement of the M60 by the M 5. Even though the SAW is lighter, there was concern about losing the firepower in exchange for mobility enhancement, so the Infantry was pushed to retain the same 7.

The dilemma led to categorizing the M as a light machine gun and the M60 as a medium machine gun. Seeking the optimum mix of firepower and reliability in the 7.

The Army already had a coaxial version of the M, so it opened the door to upgrade either the M60 or M There was basically a shoot-off between the two weapons: One was the M60E4, and the other was the ME4, which became known as the M Bravo.

The M is now being produced by its U. During the shoot-off competition, the ME4 reportedly demonstrated greater reliability; it had an operational stoppage rate of less than one stoppage per 10, rounds for the ME4 versus one stoppage in fewer than 1, rounds for the M60E4. This reliability came at a weight penalty, however, when compared with the M60E4. Moreover, Zienowicz notes that recent operational testing has pegged MB reliability at one stoppage in more than 40, rounds.

Along with increased reliability, MB performance characteristics include gas operation, fixed headspace and timing, muzzle velocity of 2, feet per second, maximum range of 3, meters tracer burnout at meters and operator adjustable rates of fire of or rounds per minute.
