摘要

The gun barrel comprises an inner bore (2) which is arranged eccentrically inside a protective sleeve (3). This, together with intermediate layers (11 -14) between the two, produces unsymmetrical thermal conductivity in the inner bore and compensates for uneven temperature increases produced when firing.
