Abstract: A heat dissipation assembly for use with a barrel forming a part of a firearm upper receiver. An annular shaped barrel nut is adapted to secure the barrel to the upper receiver. An elongated handguard is affixed to the barrel nut at a heat conducting location, the handguard adapted to surround a proximal extending portion of the barrel, the handguard having a plurality of apertures defined therethrough. At least one cooling element is located on an exterior of the handguard. A thermoelectric generator is incorporated into the handguard for transferring heat from the barrel nut to the cooling element. A fan component is integrated into the handguard and operated by the thermoelectric generator for drawing air through the apertures in order to provide additional cooling to the barrel.
