Product Summary
The BarrelCool Barrel Cooler & Indicator Flag is a unique, patent-approved accessory that combines a safety chamber flag with a high-powered blower fan. Designed to fit into the chambers of both Bolt-Action and AR rifles, it pushes air through the barrel to quickly return it to ambient temperature. This helps shooters improve precision and accuracy between strings by effectively controlling barrel heat. Additionally, it meets NRA-approved standards for chamber flags, making it a functional safety tool for ranges and competitions. The product comes ready to use with three included CR123A batteries.
