The MagnetoSpeed RifleKuhl Barrel Cooler is a compact accessory that forces ambient air down the bore to reduce barrel temperature and shorten wait times between shooting strings. It is powered by a single CR123A lithium battery (included) and uses a turbocharger-inspired impeller with an extendable nozzle to direct airflow into the barrel. The unit doubles as a chamber flag, incorporates a built-in replaceable air filter to limit dust ingress, and includes a strong neodymium magnet and metal belt clip for convenient handling and storage.
