Abstract
A firearm with a barrel fixed to a firearm body by at least one screw, wherein the firearm body includes a housing to receive the barrel and wherein the screw is fixed to the firearm body so that the firearm body tightens against or grips the outer surface of the barrel. In order to strengthen the connection between the barrel and the firearm body and fully ensure that the former does not move in either a longitudinal or rotary direction in relation to the latter, the barrel includes at least one surface hollow on its outer surface, and part of the screws already fixed to the firearm body are arranged inside a surface hollow, so that the screws inserted partly into the surface hollow provide longitudinal and rotary locking of the barrel against the firearm body.
Claims17
A firearm comprising:
- a barrel fixed to a firearm body by means of at least one screw, wherein the firearm body comprises a housing to receive the barrel and wherein the screw is fixed to the firearm body so that the firearm body tightens against or grips an outer surface of the barrel;
- and
- wherein the barrel comprises at least one surface hollow on its outer surface, and a part of the screw already fixed to the firearm body is arranged inside the surface hollow, so that the screw inserted partly into the surface hollow prevents potential longitudinal movement of the barrel in relation to the firearm body.
A firearm comprising:
- a frame defining a housing;
- a barrel comprising an end adapted to be received and engaged within the housing of the frame, the barrel further comprising a recess;
- and
- a screw for engagement within a bore through the frame, wherein a portion of the screw extends into the recess of the barrel when the end of the barrel is received in the housing of the frame and the screw is installed into the bore, thereby resisting movement of the barrel relative to the frame.
A firearm comprising:
- a barrel having a surface hollow formed in an external surface thereof;
- and
- a firearm body defining a housing for receiving an end of the barrel, the housing having a proximal side and a distal side with a gap between the proximal and distal sides, the firearm body defining a bore for receiving a screw,
- whereby engagement of the screw within the bore draws the distal side of the housing toward the proximal side to tighten the gap and engage the end of the barrel within the housing, and positions a portion of the screw within the surface hollow of the barrel.
