摘要： The invention relates to a breech system for a firearm, having a bolt receiver and a bolt; the bolt receiver is embodied in the form of a hollow cylinder at least with engagement means protruding radially inward and there is also at least one bolt head, which has outward-protruding engagement means that correspond to the inward-protruding engagement means; the bolt head is supported in rotary fashion on a bolt carrier and there is also a bolt body, which is able to slide on a bolt head shaft of the bolt head, and between the bolt body and the bolt carrier, there is at least one compression spring, which tends to move the bolt body in the direction toward the bolt head; and on the bolt head shaft and on the bolt body, there are means that produce a rotation of the bolt head when the bolt body is slid on the bolt head shaft.
