Push-in barrel for large-calibre firearms

摘要

A push-in barrel is proposed for large-calibre firearms, having a holding part on the cartridge chamber side and an adjusting bush on the mouth side, the adjusting bush having a central axial stepped hole by means of whose smaller diameter it is locked firmly on the push-in barrel, and whose external diameter is pushed into the choke bore in a fitting manner. The holding part has a plurality of collars of different diameter by means of which axial locking of the push-in barrel in the carrier barrel takes place on the one hand and, on the other hand, by means of which a radial fit is achieved.
