Abstract
A metal tube provides a bearing for a bolt carrier in a rifle. The tube is machined to provide openings and co-molded with a polymer outer shroud to form a lightweight composite upper receiver. The tube has an inner surface that supports the bolt carrier in its reciprocal motion during cycling of the rifle action during firing. The length and diameter of the tube are designed to prevent tilt of the bolt carrier during operation.
