HOW WELL DOES BARRELCOOL WORK?
WHAT IS BARRELCOOL?
Do you want a device that can cut the cooling time in half on your hot barrel? Barrelcool is a patent pending, empty chamber flag and barrel cooling device in one. It is used to cool the barrel during cease fires and between strings of fire while indicating to everyone around that your firearm is in a safe condition. Insert barrelcool into the chamber of your rifle and turn it on. Barrelcool will force air into the bore of the rifle, cooling the barrel from the inside, out.For more information see Facebook and YouTube.
