JP Enterprises AR-15 Thermal Dissipator JP Light Contour Short Black

The extruded sleeve of the Thermal Dissipator is split into two parts which can be clamped over a properly contoured barrel. Designed specifically for JP Supermatch barrels, the heat sink clamps on between the gas block and receiver. The dissipator will also fit other barrels that are contoured to the proper dimension under the handguard. The low profile design allows the use of most free float handguards.
