Check the primer for strike marks. If it looks normal, the ammunition is probably faulty. Continue firing. If

there is no mark in the primer, replace the firing pin.

If the case remains in the chamber the extractor is faulty. Replace extractor.

If the case is extracted but not ejected, the ejector is probably faulty. The ejector should only be replaced by

an armourer.

If there is no cartridge in the chamber the magazine might be dirty. Clean the magazine.

If the bolt does not close completely it might be because the chamber is dirty. Clean the chamber. If the bolt

is far from closing (at least 1 cm of the case visible) there is probably case neck remnants in the chamber.

The chamber must in most cases be cleaned out by an armourer.

13. Function

When the rifle is loaded and ready to fire the bolt assembly is in the forward position and a cartridge is in

the chamber. The bolt carrier pushes down on the rear end of the bolt in front of the locking lug in the

bottom of the receiver. The bolt carrier encloses the rear end of the gas tube.

The hammer is locked back against the sear.

When the trigger is released the hammer strikes against the firing pin whereupon the shot is fired. The

powder gases pushes the bullet through the bore and at the same time pushes against the bolt. The bolt does

not move as it is locked against the locking lug. When the bullet passes the gas cylinder gas flows through

the gas tube and pushes the bolt carrier back. When the carrier has moved a few millimeters back the bolt is

lifted out of it’s lock and follows the carrier backwards.

During the rearward movement the empty cartridge case is pulled out of the chamber and thrown out of the

weapon. The hammer is cocked and the recoil spring is squeezed together. The rearward movement is

stopped by the receiver cap.

When the movement has stopped the recoil spring pushes the bolt assembly forward. A cartridge is thereby

pushed out of the magazine and into the chamber. The bolt assembly stops in the forward locked position.

To be able to fire once again the trigger has to be released so that it grips the sear.

When the magazine is empty the cartridge follower pushes up the bolt lock so that the bolt assembly stops

in the rear position.
