[10] It is said to be more accurate than all its predecessors due to a heavier, removable, partially forced-air-cooled barrel with radial cooling ribs and a handle which eliminates the haze effect from hot gases and keeps the barrel cooler, making the weapon more reliable.

When conducting a long firefight, it can safely fire up to 1000 rounds of ammunition per hour without degrading the combat characteristics and reducing the life of the barrel.

Middle part of the barrel, from the front of the trunnion, to the gas block has transverse grooves to increase the surface area for better cooling.

There are oval holes on the jacket in the ribbed section of the barrel for access of air.

Low pressure created at the front of the jacket during firing draws cool air through the grooves, cooling the front part of the barrel, similarly to the Lewis machine gun.
