A unique, patent pending, product that combines the safety of a chamber flag and a fan to cool your barrel on your rifle. Barrelcool offers the most compact and quickest barrel cooling on the market.
A small, convenient package, that fits right into the chamber of your Bolt-Action or AR Rifle. A powerful blower fan pushes air through your barrel, and returns it to ambient temperature, enabling you to shoot with more precision and accuracy.
The Caution-Yellow paintjob makes BarrelCool fit the standards for an NRA-approved Chamber Flag. Required at many ranges and competitions, a chamber flag indicates the firearm is free of any ammunition, and unable to fire. BarrelCool is a chamber flag that doubles as an enhancement for your rifle!
