Caveman, llc has come up with a simple way to tell you if your barrel is safe and ready to be stored. The FLARE Mini is placed on your barrel after removing the flash suppressor. It starts off brown in color and changes to bright orange when the temperature of your barrel exceeds 131 degrees Fahrenheit. As the barrel cools to a safe temperature it changes back to brown.
