Description

The M2 .50 cal machine-gun was utilized in various roles during the Second World War. It was mounted on tanks, in fighter aircraft, used for self-defense by bombers and as an Anti-aircraft weapon by troops on the ground.

However, prolonged firing caused the barrel of the .50cal machine-gun to overheat; this could lead to problems with accuracy and potential damage to the weapon itself. Therefore, a water-cooled version of the .50cal machine gun was designed to improve barrel cooling and reduce the occurrence of these problems.

There were no differences between the workings of the air-cooled and water-cooled versions, but externally a jacket containing 10 quarts (9.5 liters) of water surrounded the barrel of the water-cooled version. Upon firing, a hand pump was used to create a flow between the jacket and an auxiliary 8 gallon (30.3 liters) water chest connected to the gun by a pair of hoses. This flow provided an effective means of cooling the barrel during prolonged periods of firing.
