When the bolt is thrust forward, the ejector is pressed to the left. The bottom of the bolt face strikes the top cartridge in the magazine and pushes it ahead into the firing chamber. As the cartridge is forced ahead, its base is compelled to rise up the bolt face until the extractor catches in the cartridge groove.
When the bolt is about one inch from closing, the cocking stud is engaged by the sear. This results in the cocking-piece and the striker being held bac\, while the bolt and bolt plug are pushed forward. This action compresses the mainspring completely. (Note: This cocking system applies only to the early Belgian, Spanish and Turkish types. In German and other late types, turning down the bolt handle completes cocking.)
This final motion of course completes thrusting the cartridge forward into the chamber.
As the bolt handle is turned down to the right, the bolt cylinder is revolved and the two lugs at the front end are turned into engagement in the recesses cut for them in the receiver directly behind the head of the cartridge. Pulling the trigger levers the sear away from the cocking stud.
The striker is now released and the tooth on the cocking-piece enters the cam recess on the bolt permitting the striker freedom to reach the primer when released.
If the bolt is not completely closed, the travel of the striker is blocked, since the tooth of the cocking stud is not opposite its entering recess. Hence the rifle cannot be fired.
All Mauser rifles wherever they are made or under whatever name manufactured are merely modifications of this original Belgian design.
