A firearm heat sink is provided that may be easily affixed to, and removed from, a firearm. The heat sink is provided with a plurality of cooling fins. In a preferred embodiment, the firearm heat sink is held in place by a cooperating collet and ring on each end of the heat sink. In an alternate embodiment, the firearm heat sink is formed in halves and is mechanically fastened together about the barrel of the firearm. In either embodiment, an underlying heat conducting material optionally may be added to insure a proper thermal path between the firearm and the heat sink.
