ABSTRACT:
Before the empty cartridge case is ejected it is extracted from the cartridge chamber of the weapon barrel by an extractor and subsequently tilted by an ejector. During this operation large forces are exerted on the pivotably mounted extractor. It has been found that when high cadence firing takes place the spring forces are too small to hold the extractor reliably. Therefore, the extractor is secured by a support lever or by a locking pawl against inadvertent pivoting during the removal of the cartridge case. Preferably a support lever or support slide is arranged in the breechblock to prevent premature tilting of the cartridge case.
