FUNCTIONING

1. COCKING

Before firing, the breech block mechanism is

forward, with the safety applied (change lever set

‘5”).

Insert a filled magazine obliquely in the housing

under the receiver, swing it from front to rear and

push fully home:

the magazine is then. secured

in the rifle at both front and rear.

Pull the cocking handle, on the left side of the

receiver, fully to the rear, then let it go forward: a

cartridge is thus introduced into the chamber;

the rifle is loaded and cocked.

To fire, set the change lever either at “R” for

semi-automatic fire, or at “A” for automatic fire.

2. REAR MOVEMENT OF THE MECHANISM

Pressing the trigger fires the shot.

When the bullet passes the gas port in the bar-

rel, port of the combustion gases penetrate the

regulator and thence into the gas cylinder.

The.

piston is projected to the rear, strikes the

breech-

block slide, which is also driven rearwards.

After

recoiling a few millimetres, the ramps of the slide

force the rear part of the breech block to rise,

thus lifting it out of engagement with its locking
