Upgrading the U.S. Army’s M2 .50 Caliber Machine Guns

The U.S. Army is in the process of upgrading its M2 .50 Caliber Machine Guns to the new M2A1 configuration. The upgraded weapon system offers Soldiers increased performance as well as new features and design improvements. They include fixed headspace and timing, a quick change barrel with removable carrying handle, a new flash hider that reduces the weapon’s nighttime signature by 95 percent, and a trigger block safety.

The M2 “Ma Deuce” is a belt-fed, heavy machine gun that mounts on most aircraft and vehicles, and can be fired from the new M205 tripod (See video at http://bit.ly/1lbJ4Ql). The system is highly effective against light armored vehicles, low- and slow-flying aircraft, boats and enemy personnel. The Army developed the M2A1 to increase the warfighter’s lethality and survivability on the battlefield by providing system upgrades to the M2.
