Mitraliera calibru 12.7 x 108 mm

The machine gun is a gas operated, belt fed, air
cooled machine gun that fires from an open bolt and in
automatic mode only. The gas piston and chamber are
located below the barrel; the gas piston is of the long stroke
type, and is attached to the bolt carrier. The gas chamber is
fitted with a gas regulator that can be adjusted. The bolt, of
rectangular cross-section, locks into the receiver with two
outwardly pivoting flaps. These flaps are pushed outwards
from the bolt to lock it by the enlarged firing pin, which in
turn is operated by the vertical projection on the bolt carrier.
The rear of the receiver houses two spring buffers, one for
the bolt and one for the bolt carrier.
