摘要

The holder (8) near the barrel mouth comprises a guide piece (20) fixed only to the first barrel with a longitudinal groove (21) and a rib (26) engaging on the second barrel (2) in the longitudinal groove with clearance. The rib has a longitudinal bore (27) and fits in a longitudinal direction in the longitudinal groove by a releasable pin (24). The guide piece is part of a middle rail (6) from the front connecting surface (29) of which the pin is screwed in. The part of the pin located in the longitudinal groove is finely machined.
