Type 85 heavy machine gun (PR China)
Type 85 heavy machine gun with telescope sight
Caliber: 12,7x108mm (also 12,7x99mm / .50BMG in W95 version) The Type 85 heavy machine gun can be considered as a further evolution of the Type 77 heavy machine gun – most of the improvements concentrated at either end of the basic weapon. The Type 85, like its predecessor, was also used as a ground and vehicle weapon. It is currently in service with PLA, along with earlier Type 77. Recently, China has disclosed an export version of the Type 85 machine gun, known as W95. This gun is similar to Type 85 except that it is chambered for 12,7x99 NATO / .50BMG ammunition.
The Type 85 heavy machine gun is broadly based on the Type 77,
but with certain improvements. It uses the same direct-impingement gas
system with flap-locking bolt; the belt feed system also is similar to
the
Type 77. The key difference between the Type
85 and its predecessor is in the arrangement of the trigger and cocking
system, which is patterned after the pre-WW2 Czechoslovak ZB 53 / vz.37
machine gun. The trigger module of the Type 85
machine gun is a separate unit which is attached below the receiver and
can slide forward and back. To cock the bolt (as the gun fires from an
open bolt) one must release the trigger unit lock, then push the
trigger unit forward using horizontal spade grips which are attached to
the unit. Once the trigger unit is its forward position, its sear
engages the bolt, so retraction of the trigger unit causes the bolt
group to unlock and go rearwards. Once the trigger group is fully
retracted, it is locked in place by its own lock, and holds the bolt in
a cocked position until the trigger is released. --
