Short JP Thermal Dissipator™ for 308 JP Supermatch barrels. Fits JP 18"e; 308 barrel. Can be used on any barrel with .750 contour and mid length gas system under hand guard.
Compatibility notice: Note that the JP Thermal-Dissipater™ is designed specifically as a JP Supermatch™ barrel accessory and will not fit most other barrels unless they have exactly the contour and interface length necessary. Most non-JP barrels will need to be re-contoured to incorporate the JP Thermal-Dissipater™. For a pdf showing the critical dimensions, click here.
