The shutter has a chamber grip (13) fitted by a recoil lever (10) on one side to a chamber sleeve (1), and on the other side by a holding bolt (11) in a movable control sleeve (2). The weapon's rear hammer spring (25) can be tensioned and locked in the chamber sleeve by an arrester (3). The shutter head can be turned by an attachment of the control sleeve, so that when the chamber grip of the shutter head recoils, the locking piece of the barrel can be unlocked. Similarly, it is locked when the chamber grip moves forward. |
