necessary for normal functioning, without causing

undue wear on the various parts of the mechanism.

Turning the gas regulator to the right (clock-

wise) reduces the opening by which gas escapes,

thus increasing the quantity or “intake” gas used

to drive the piston to the rear.

Turning the gas regulator to the left (anti-

clockwise) causes the opposite effect: gas escape

is increased and the balance available to work the

piston is decreased.

By a system of “clicks” and engagement of the

gas regulator spring, the regulator has 13 different

positions (12 “clicks” to open fully).

To make setting in any given position easier,

figures are engraved on the gas regulator, the

figure 1 corresponding to the completely closed

position and one figure for every 2 “clicks” open-

ing.

Example: when the figure 5 is opposite the

gas hole, the gas regulation corresponds to

8 “clicks”.

Method of gas setting

There are several different ways of finding the

correct adjustment but we suggest the following

method, which has, we think, proved itself the

best :-

- Insert an empty magazine in the rifle;

All firing is carried out by inserting the car-

tridges by hand, one by one into the empty

magazine, through the ejection opening.

The correct setting is determined by the

point at which the holding open device

engages the mechanism and holds it to the

rear, or fails to do this.
