ABSTRACT:
The invention relates to bearing means for a gun barrel (3) mounted in the breech casing of a weapon in which the breech casing comprises a sleeve member (2) enclosing a rear part of the gun barrel (3). The bearing means comprises a cylindrical sleeve (10) positioned between said breech casing sleeve member (2) and the adjoining external gun barrel surface. The sleeve (10) is provided with a spring part which consists of a plurality of finger springs (17) distributed about the peripheral surface of the gun barrel and engaging by the force of spring an enlarged cylindrical part (7) of the external gun barrel surface. This enlarged, cylindrical part (7) has such a length (d) in the longitudinal direction of the gun barrel that the finger springs (17) are engaged to said part (7) during the first phase of the recoil during which the shell, projectile or the like has not yet left the bore of the barrel (3). By means of this invention any play in the bearing means can be compensated so that the spread of shots is reduced.
