An assembly of a receiver (1) with a barrel (4) wherein the barrel (4) is inserted into a barrel hole (7) in the receiver (1) and is attached in a replaceable manner by means of a clamping connection that comprises a longitudinal slot (2) that longitudinally divides the receiver (1) wall in the insertion location of the barrel (4). In the location of the longitudinal slot (2) at least two transversal screws (3) pass through the receiver (1). In the location of the longitudinal slot (2), a transversal hole (5) extends into the receiver (1) and a transversal pin (10) passes through the transversal hole (5) in such a way that the transversal pin (10) reaches into a corresponding transversal recess (9) in the barrel (4). Perpendicularly to the longitudinal axis of the transversal pin (10) a threaded hole (11) with a connecting screw (12) passes through the transversal pin (10). The connecting screw (12) further passes through a straight-through hole (6) in the receiver (1) and through a stock/frame (13) of the firearm to connect the receiver (1) to the stock/frame (13) of the firearm.
An assembly of a receiver with a barrel, wherein the barrel is inserted into a barrel hole in the receiver and the barrel is attached in a replaceable manner by a clamping connection that comprises a longitudinal slot that longitudinally divides the receiver wall at the insertion location of the barrel and at least two transverse screws configured to pass through the receiver at the longitudinal slot, and a transverse hole extends into the receiver at the longitudinal slot and a transverse pin passes through the transverse hole in such a way that the transverse pin is received in a corresponding transverse recess in the barrel, the transverse pin having a threaded hole extending perpendicular to the longitudinal axis of the transverse pin and a connecting screw received in the threaded hole, wherein the connecting screw further passes through a straight-through hole in the receiver and through a stock/frame of the firearm to connect the receiver to the stock/frame of the firearm.
