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 soldier. No tools are required when stripping the weapon. A brief description of the components is as follows: (fig.4) The barrel assembly is air-cooled and contains a post type front sight and a flash suppressor. The flash suppressor also serves as a grenade launcher and bayonet mount. The foldingstock is of rugged lightweight construction. When extended, it locks into Position secured by means of a spring loaded locking mechanism.
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 case from the chamber and only after the completion of the unlocking action do the bolt carrier and the bolt retract together backwards, thus finishing the extraction operation. When the boltcarrier moves backwards the return spring contracts and the empty cartridge case is thrown out through the ejection port by the ejector. During the retraction of the boltcarrier and bolt, the hammer is cocked and engaged to the trigger sear. Forward Movement When the return spring expands, it drives the boltcarrier and bolt forward. One cartridge is pushed out from the magazine by the bolt and fed into the chamber. In the meantime the extractor “grips” the cartridge case rim. The continuation of the forward movement causes the bolt to rotate and thus, through the locking lugs, locks the bolt against the receiver. When the locking action is completed the bolt carrier’s grade reaches the automatic sear to turn and release the hammer. When pulling the trigger, the hammer is disengaged from the trigger sear and hits the firingpin which strikes the primer of the cartridge inside the chamber.
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 lever is located above the disconnector while the trigger’s sear engages the hammer (hammer spring is compressed). At the end of the forward movement the bolt carrier disengages the automatic sear from the hammer’s grade. The hammer is now engaged by the trigger’s sear only. When pulling the trigger the hammer is released, hitting the firing pin.
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 pulled. When the trigger is released the hammer is engaged by the trigger’s sear and the firing stops. Fire Selector Lever on Semi-Automatic “R” Position(figs. 7A & 7B)In this position the fire selector lever does not act either on the trigger or on the disconnector. Pulling the trigger operates the disconnector causing it to engage the hammer, preventing it from moving upward. In this mode the rifle will fire one round each time the trigger is pulled. In order to fire another cartridge the trigger must be released. When releasing the trigger the disconnector releases the hammer which, in turn, is engaged immediatly by the trigger’s sear. Pulling the trigger causes the release of the hammer from the trigger sear, thus hitting the firing pin.
