The Army found an M2 .50 caliber machine-gun still shooting perfectly after 90 years of service
The .50 caliber M2 machine gun was designed in 1918, near the end of World War I by John Browning.
Production began in 1921 and the weapon was designed so a single receiver could be turned into seven different variants by adding jackets, barrels or other components.
Roughly 94 years after the first production run of M2 machine guns came off the assembly line, the 324th weapon produced made it to Anniston Army Depot for overhaul and upgrade.
In more than 90 years of existence, the receiver with serial number 324 has never been overhauled.
“Looking at the receiver, for its age, it looks good as new and it gauges better than most of the other weapons,” said John Clark, a small arms repair leader.
Despite the fact that the weapon still meets most specifications, it may be destined for the scrap yard.
Modifications made to the weapon in the field mean part of the receiver would have to be removed through welding and replaced with new metal, a process which usually means the receiver is scrap.
“I’d rather put this one on display than send it to the scrap yard,” said Clark, adding the weapon’s age makes it appealing as a historical artifact.
Currently, the 389th M2 is on display in the Small Arms Repair Facility. There is an approval process the older weapon would have to go through in order to be similarly displayed. Clark and Jeff Bonner, the Weapons Division chief, are researching and beginning that process.
In 2011, the depot began converting the Army’s inventory of M2 flexible machine guns to a new variant.
The M2A1, has a fixed headspace, or distance between the face of the bolt and the base of the cartridge case, and timing, the weapon’s adjustment which allows firing when the recoil is in the correct positon.
In the past, every time a Soldier changed the barrel on the M2, the timing and headspace had to be changed as well. If that wasn’t done properly, the weapon could blow apart. The fixed headspace and timing eliminates this risk to Soldiers.
“It only takes 30 seconds to change out the barrel on the M2A1 and you’re back in business. The M2 Flex version could take three to five minutes, depending upon your situation,” said Jeff Bonner, weapons division chief.
Bonner said this is the first major change to the M2 weapon system since the machine gun was first fielded.
Since the overhaul and upgrade work began in fiscal year 2011, the depot has brought more than 14,000 of these .50 caliber machine guns to better than new, and upgraded, condition.
Once the weapon is rebuilt, it has to be readied to be fired, repeatedly, without jamming or suffering other mechanical difficulties.
To assist with this process, a machine known as the exerciser is used to ensure the new parts work well with the old.
After all, the older parts of the weapon could be nearly 90 years old.
The exerciser simulates charging the weapon, or preparing it to be fired, 700 times.
