A thermal mirage reducing device for firearms is disclosed and described. The thermal mirage reducing device includes a heat control shell oriented along a horizontal longitudinal axis corresponding to a bore line of a firearm. A cross-sectional profile of the heat control shell taken perpendicular to the longitudinal axis is asymmetrical about a vertical plane dividing the heat control shell along the longitudinal axis. The cross-sectional profile has a heat-directing portion protruding on one side of the vertical plane. The heat-directing portion extends to a high point that is vertically higher than any other point in the cross-sectional profile and laterally offset from the vertical plane. The cross-sectional profile does not intersect the line of sight of the firearm.

1. A thermal mirage reducing device for firearms, comprising: a heat control shell oriented along a horizontal longitudinal axis corresponding to a bore line of a firearm, wherein a cross-sectional profile of the heat control shell taken perpendicular to the longitudinal axis is asymmetrical about a vertical plane dividing the heat control shell along the longitudinal axis, wherein the cross-sectional profile comprises a heat-directing portion protruding on one side of the vertical plane and a core portion encompassing the longitudinal axis, wherein the heat-directing portion extends to a high point that is vertically higher than any other point in the cross-sectional profile and is laterally offset from the vertical plane, and wherein the cross-sectional profile does not intersect a line of sight of the firearm located parallel to the bore line and vertically above the cross-sectional profile. 2. The device of claim 1, wherein the cross-sectional profile is a teardrop profile wherein the high point is at a tapered tip of the teardrop and the heat-directing portion comprises a proximate edge and a distal edge which meet at the tapered tip of the teardrop, wherein the proximate edge is nearer to the line of sight than the distal edge. 3. The device of claim 2, wherein the cross-sectional profile is an arcuate teardrop profile, wherein the proximate edge is arcuate such that the proximate edge is concave recessed toward the distal edge. 4. The device of claim 2, wherein the cross-sectional profile is a straight-edged teardrop profile, wherein the proximate edge is substantially straight running from the tapered tip of the teardrop to the core portion. 5. The device of claim 2, wherein the heat control shell is adapted to be removably attachable to a firearm barrel or muzzle attachment, wherein the heat control shell comprises a distal face corresponding to the distal edge of the cross-sectional profile, and wherein the distal face includes a plurality of convective heat apertures into an interior space of the heat control shell. 6. The device of claim 2, wherein the heat control shell comprises a distal face corresponding to the distal edge of the cross-sectional profile, and wherein the distal face includes a plurality of heat transfer fins. 7. The device of claim 1, wherein the heat control shell is adapted to be removably attachable to a firearm barrel or muzzle attachment, and the heat control shell defines an interior space. 8. The device of claim 7, wherein the heat control shell comprises a slot oriented remote from the heat-directing portion of the heat control shell and running substantially parallel to the longitudinal axis along an entire length of the heat control shell. 9. The device of claim 7, wherein the interior space is configured in size and shape to form a friction fit with a firearm barrel or muzzle attachment. 10. The device of claim 7, wherein the interior space is configured in size and shape to receive a cylindrical muzzle attachment. 11. The device of claim 7, wherein the interior space is configured in size and shape to receive an octagonal muzzle attachment. 12. The device of claim 1, wherein the heat control shell is formed of a rigid material. 13. The device of claim 1, wherein the heat control shell comprises a thermally conductive material having a high thermal conductivity. 14. The device of claim 13, wherein the thermally conductive material is selected from the group consisting of aluminum, steel, copper, carbon fiber, composites thereof, alloys thereof, and mixtures thereof. 15. The device of claim 1, wherein the heat control shell is integrated with a firearm barrel or a muzzle attachment. 16. The device of claim 1, further comprising a firearm associated with the heat control shell such that the bore line of the firearm is coaxial with the longitudinal axis of the heat control shell. 17. The device of claim 16, wherein the high point of the heat-directing portion is sufficiently laterally offset that a hot air plume rising vertically from the high point does not intersect the line of sight of the firearm. 18. The device of claim 1, wherein the heat control shell is hinged. 19. The device of claim 1, further comprising a retention clip adapted to removably attach to the heat control shell and conformably restrain the heat control shell to promote a friction fit between the heat control shell and a firearm barrel or muzzle attachment. 20. The device of claim 1, further comprising an insulator layer disposed on an inside surface of the heat control shell above the longitudinal axis.
