ABSTRACT:
A liner for the firing chamber of a gun, designed to prevent ammunition "cook-off". The liner minimizes flow of heat into the chamber wall, incident to the combustion process. The liner also retards the flow of heat in the reverse direction, i.e. from the chamber wall into a chambered round. Liner design is such that the liner can be removed and replaced by a new liner when it is damaged.
