Basic Field Stripping

FIELD STRIPPING

The rifle has been designed to make stripping and assembly easy for the user. No force need be exerted if stripping is done in the correct order. To facilitate assembly, care should be taken when stripping to lay out the parts on a clean level surface, in the order in which they are removed. This will prevent loss of parts and make assembly easier, as this is done in reverse order to stripping. The rifle operator should know each step in field stripping so well that he can do it in the dark. No tools are needed, but it may be necessary to use the nose of a bullet.

1. Remove the magazine.

2. Cock the mechanism to make sure there is no cartridge left in the chamber; let the mechanism go forward and put the rifle at safe, the hammer remaining in the cocked position (fig. 10).

3. Stripping the mechanism

Press the trigger frame body lock lever, on the left side of the trigger frame upwards; hold the barrel group firmly and press the butt trigger group downwards, swinging the rifle open like a shotgun, (see fig 12).

5. To separate the bolt from the bolt carrier, disengage the fore part of the breech block from the slide and continue this movement, levering the rear part of the breech block and at the same time exerting pressure with the thumb on the rear end of the firing pin (fig 15)

When the retaining pin has been removed, the firing pin will be pushed from its housing by its spring (fig 17).

6. To remove the firing pin, press on the rear end of the firing pin, push out the retaining pin; if the pin does not fall out easily, use the nose of a cartridge see (fig 16).

When the retaining pin has been removed, the firing pin will be pushed from its housing by its spring (fig 17).

7. To remove the gas plug, press in the plunger of the gas plug, lurn gas plug a quarter turn clockwise In this position the plug will be pushed from it housing by the piston spring.

8. Remove the piston and spring from the gas cylinder (fig 18)

Note: There is no need for the operator to strip the extractor. It is necessary to use a cartridge for this, or a special tool, and it is normally done by the factory when making of periodic inspection.

9. Assembly after field stripping

• Replace the piston spring on the piston rod (fig. 19).

• Replace the piston and its spring in the gas cylinder (fig. 18).

• Insert the gas plug, compressing the piston spring, with the big end of the plunger turned towards the barrel.

When the gas plug is fully home, rotate it one-eighth of a turn, so that the letter "A" moves upwards.

• Push the plunger and rotate so that the letter "A" appears uppermost.

• Replace the firing pin spring and the firing pin in the bolt carrier (fig. 16, 17); compress the spring by working the firing pin and replace the pin.

• Replace the bolt in the bolt carrier, inserting the rear part obliquely in the slide (fig. 15).

• Exert pressure on the bolt carrier so that the firing pin spring is slightly compressed and the bolt is swung downwards into its correct position in the bolt carrier.

• Insert the ribs of the cover in the corresponding grooves in the receiver and slide the cover fully forward.

• Replace the mechanism in the body, inserting the ribs of the bolt carrier in the corresponding grooves in the receiver.

• When this is done, the bolt carrier should be in its forward position and the muzzle of the rifle pointing downwards; the mechanism will then fall into position correctly.

• Close the rifle, still holding the muzzle down-wards, to prevent any possibility of the bolt carrier rod protruding.
