34
After the locking rollers have been fully cammed into the bold head, the
bolt can continue its recoil movement. In the course of this movement,
the empty cartridge case is ejected and the hammer recocked.
At the same time, the recoil spring is compressed, which returns the bolt
to its forward position. During the course of this process, a new round is
chambered from the magazine. The extractor engages the extracting
groove in the cartridge case. As a result of the bevelled surfaces of the
locking piece, the locking rollers are cammed against the supporting
surfaces in the barrel extension (Fig. 34). The weapon is now ready to fire
again.
