The Army has decided to cut the XM806 Lightweight .50 Caliber Machine Gun program. The XM806 was a scaled down version of the 25mm XM307 Advanced Crew Served Weapon, which was also cut before it went into production.
The XM806 was originally going to be deployed this year, but delays pushed the expected deployment date back to late 2013 or early 2014. Military Times reports that the money allocated to the XM806 will be used to upgrade the Army’s .50 M2 Browning machine guns to the M2A1 version. Earlier this year the Army announced plans to upgrade every M2 to the M2A1.
