Abstract: A flexible cylindrical fabric rifle cover for mitigating heat mirage, including an inner textile tube having a major axis, an outer textile tube positioned around the inner textile tube and sharing the major axis, and a plurality of middle textile tubes sandwiched between the inner and outer tubes and sharing the major axis. A plurality of thread guides are connected to the outer tube. A poly-para-phenylene terephthalamide thread runs through the thread guides and has a first end connected to the outer tube and a second end connected to a rotary reel affixed to the outer tube. The outer tube is an aramid ripstop fabric, the inner tube is an amorphous silica cloth, and the respective middle tubes are selected from the group consisting of aluminized silica fabric, basalt fiber fabric, silicone coated aluminized fiberglass fabric, poly-para-phenylene terephthalamide fabric, and aramid ripstop fabric.
