2. Firing mechanism function (fig. 16).

a) One shot at a time.

With the safety in the <<T>> position, the rear end of the disconnector (3) fits

into a slot in the safety shaft (6) and the forward extreme protrudes. When the

trigger is pulled (1), the firing lever (2) releases the hammer (4), that due to the

action of its spring hits the firing pin and produces the shot. The bolt assembly,

during its rearward travel, mounts the hammer (4), that is then held by the

front hook of the disconnector (3). When the trigger (1) is released, the

hammer (4) is released from the disconnector and is again held by the firing

lever (2). If the trigger is pulled before the bolt assembly is locked, the hammer

is retained by the safety lever (5). When the bolt assembly reaches its most

forward position, (locked), the protrusion on the rear end of the bolt support

hits the safety lever (5), making it rotate on its shaft and in this way freeing the

hammer from the hook on said lever. Therefore, it is not possible that a shot

can be produced without the weapon being perfectly locked.

b) In bursts.

With the safety in the <<R>> position, the rear end of the disconnector (3) falls

on the solid part of the safety shaft (6) and its forward end is hidden. When a

shot is produced, the hammer (4) during its rearward travel cannot be retained

by the disconnector (3), being in this case held by the inferior arm of the safety

lever (5). When the bolt assembly gets to its most forward position (locked), the

protrusion on the rear end of the bolt support hits the protruding arm of the

safety lever (5), forcing it to rotate and to release the hammer (4). Therefore, as

long as the trigger is squeezed and cartridges remain in the magazine, the

weapon will fire automatically, only the safety lever acting to retain the

hammer.
