Abstract
A heat dissipating and strength enhancing cover for a firearm gas tube includes a wire helix formed of closely adjacent coils having an inner diameter sized to closely fit over and in contact with an exterior surface of a gas tube. The wire of the gas tube cover may be made of a Beryllium-Copper alloy and have sufficient flexibility to accommodate at least one bend in the gas tube. The ends of the gas tube cover may be formed to a substantially flat surface that is substantially perpendicular to a longitudinal axis of the helix and may include caps covering first and second ends of the gas tube cover. The caps may prevent rotation of the cover when installed. The cover may extend substantially between a gas block and means for mounting a barrel when installed.
