SEGMENTED COMPOSITE BARREL FOR WEAPON

摘要

A rifle barrel (10, 10b, 10c, 10d) for a gas-operated rifle includes a metallic liner (14, 14b, 14c, 14d) with a longitudinal bore and a transverse gas port (22, 22d) through the liner to the bore intermediate along a length of the liner. A thermally conductive sleeve (26, 26b, 26c, 26d) circumscribes the liner substantially along the length of the liner. A composite wrap circumscribes (30, 30b, 30c, 30d) the sleeve substantially along a length of the sleeve. The composite wrap is separated from the gas port.
