DESCRIPTIONThe Galil assault rifle (Models ARM
, AR
 & SAR
) is a multi-purpose personal weapon,
Designed to serve as a basic weapon for the infantry squad.
The rifle 
(fig. 1, 2 & 3)
 it is a lightweight, aircooled, gas-operated, magazine-fed,
Shoulder or hip fired weapon. It can be used as an assault rifle and light machine gun
(ARM
: with bi-pod, carrying handle & stock extended). By use of a fire selector lever, the
weapon fires automatically or semi-automatically. 

The rifle’s flashsuppressor also serves as a grenade launcher (ARM
 & AR
 -standard,
SAR
 –optional) In the ARM
 model the bipod also serves as a wirecutter. The Galil is
deployed in each of these models without any change of parts or addition of adapters.
Outstanding ease of handling makes the Galil a unique weapon in it’s class. The
cocking lever, fire selector lever and magazine catch may all be operated from either
side of the weapon so that handling is equally easy for the right or left-handed...

The Bolt carrier, which locks and unlocks the bolt, travels in the upper part of the receiver
And accommodates the return spring.
The fire selector lever, when on safe position, positively blocks the trigger and covers
the slot in the cover in which the cocking lever travels, thus preventing the cocking of
the weapon and dirt from entering the mechanism.

FUNCTIONRetraction Movement
When the cartridge is fired the pressure of the burnt propellant causes the bullit to move
forward. When the bullit passes the gasport, gases under pressure enter the gascylinder
and push the gaspiston and thus the boltcarrier backwards (piston and boltcarrier are rigidly
connected
). The backward movement of the boltcarrier causes the bolt to rotate, because
the lug groove in the boltcarrier act upon the bolt lug. This rotary motion of the bolt releases
the empty cartridge...

Trigger Mechanism Operation
The mechanism is operated by the backward and forward movement of the boltcarrier and bolt.
It comprises the following components – Trigger, - Disconnector, - Hammer, - Automatic sear,
- Fire selector lever.
Fire Selector Lever on Safe “S” Position(fig.5)In this position the fire selector is located above the rear end of the trigger preventing its
movement and thus the release of the hammer.
Fire Selector Lever on Automatic “A” Position(fig.6)In this position the selector...

Because the trigger remains pulled and the selector is on the (automatic) “A”
  position,
(thereby preventing the disconnector from engaging the hammer) the only component
engaging the hammer and holding it against the force of the spring is the automatic sear. The
automatic sear is disengaged from the hammer at the end of the forward movement of the
boltcarrier thus releasing it. When released, the hammer hits the firing pin and fires the
cartridge. The action is repeated as long as the trigger is kept...
