ABSTRACT:
A rifle breech assembly comprises a housing adapted to receive the barrel at one end and slidably to receive the breechblock at the other end. The latter carries at its forward end locking bosses, and the housing is formed with grooves which receive the locking bosses and open into an annular recess defined by the rear end of the barrel and permitting a rotation of the breechblock. The breechblock is provided with a resilient pivotally movable extractor disposed between two locking bosses and terminating in an extractor hook. The inside surface of the housing wall constitutes adjacent to the annular recess a surface for radially supporting the extractor hook when the breechblock is locked. A recess which permits a pivotal movement of the extractor is disposed beside that supporting surface in the peripheral direction.
