Abstract
A firearm barrel includes an elongate metal insert member and a rigid sleeve surrounding the insert member along a majority of the length of the insert member. A casing is formed around at least a portion of the sleeve, preferably by injection molding. Breech and muzzle portions of the barrel may be fitted against the sleeve and are preferably tightly connected by the casing.
