18、 reloading of the rifle is based on utilizing the energy of powder gases which arc channeled from the barrel bore to the gas piston Upon firing a certain amount of the powder gases following the bullet flows through the port in the barrel bore wall into the gas chamber exerts pressure upon the front
19、 wall of the gas piston and throws back the piston with pusher and consequently the bolt support into the rearward position As the bolt support travels rearward the bolt opens the barrel bore the cartridge case gets removed from the cartridge chamber and ejected out of the receiver The bolt support

22、 Fig 5 Sling for carrying small arms Fig 6 Slip cover for sight To fire a shot it is necessary to release the trigger and press it anew After the trigger has been released the rod moves forward and its hook engages the sear and if pressed the rod hook turns the sear and disengages it from the hammer
23、 cocking cam The hammer actuated by the mainspring turns round its pin and strikes the firing pin The latter travels forward and impinges the primer Thus a shot is fired With the last cartridge fired and the bolt returned to the rearward position the magazine follower lifts the bolt catch the latter
24、 engages the bolt to stop the bolt support in the rearward position Thus it is necessary to load the rifle anew The rifle has a gas regulator which serves to change recoil speeds of moving parts Under conditions of proper servicing with the parts lubricated the gas regulator is set at division 1 On
25、firing during a long time without cleaning and lubricating and heavy soiling of the rifle stoppage may occur incomplete recoil of the moving parts In this case the regulator is set at division 2 To change the regulator from one position to another use the rim of the cartridge case or the cartridge 9
