50 BMG cut away, into the belly of the beast

50 BMG-2

I had the opportunity to photograph a pretty rare .50 Browning Machine Gun, it is a factory cut away used as a training tool for armorers of the famed Ma Deuce.

I was not able to get an exact data on this particular M2 training tool but I was told it was from around the 50s and was used as a training tool for many years before it made it’s way into a private collection.

It has been about eighteen years since I have shot a real M2 while I  was an active duty Marine but I assure you the M2 Browning Heavy Machine Gun is a fantastic firearm. If the transferable ones were not so expensive, I would have one for my very own.

The M2 Browning Heavy Machine Gun .50 was invented by none other than John Moses Browning around 1917 and was initially tested in 1918. It is basically a scaled up version of the M1919 Browning 30 caliber machine gun. It was around 1933 the design was perfected and pressed into service, and it is still issued today.

The M2 is an air-cooled, belt-fed machine gun. The M2 fires from a closed bolt, operated on the short recoil principle. It fires the .50 BMG cartridge, which offers plenty of long range accuracy and incredible stopping power.

    Very cool cut away of the Browning M2 machinegun. You do not see such things very often in gun magazines. I always loved the 50 BMG
