| (documentation M3M EnglishLanguage "The M3M is a weapon system rather than just a machine gun. The system has three parts: The Machine Gun, the Medium Pintle Head (MPH) or Soft Mount, and the Cradle, which is used to integrate the weapon into a particular aircraft or vehicle. An optional Integrated Illuminator/ Laser spotting device gives this weapon a day/ night capability. Three important differences between the M3M and the M2 BMG: 1) The new weapon uses an open bolt 2) has an internal recoil spring, and 3) a significantly longer barrel life. The first difference means that cook-offs are far less likely to occur while the second point means that the M3M has only a third as much non-compensated recoil as compared to the M2 BMG. As a personal note, I have been on a firing range where three out of four M2 BMGs had cook-offs following prolonged firing. Some problems noted during the initial evaluation of this weapon by the US Marines in 2001 included: 1) Significantly increased reload times compared to the M2 BMG. 2) Lengths of rounds were repeatedly pulled from the 100 round magazines by the airstream, resulting in hazards to personnel and equipment. 3) Lack of a flash suppressor, which made this weapon almost impossible to use with night-vision equipment. The feed system for 600 round magazines has been modified to reduce the air stream problem and FN Herstal has added a flash suppressor, as can be seen below in the second photograph.
