Learn More If you're a precision shooter, or have ever been to the range with one, you that at some point you're going to have to stop and let a rifle cool down. A hot barrel is a less accurate one, and usually long range shooters aren't the type that want to turn money into noise. To reduce the dreaded waiting period, MagnetoSpeed launched an active cooling system they named Riflekühl. This isn't the first time we've seen devices like this; several years ago Caldwell released their Accumax Barrel Cooler. However, there were some downsides. First and foremost it only worked with the AR-15 and then only those that used 5.56-sized receivers– that limits the application severely. MagnetoSpeed tells us they have a more efficient system that can drop the temperature of a barrel to ambient levels with an average of seven minutes. Inserted through the ejection port, the Riflekühl has a magnet to keep it snugged up against the bolt and the nozzle seals against the chamber to allow for the most efficient airflow. As a bonus, the Riflekühl has a replaceable 50-micron air filter (especially handy for those in desert environments) and the red color means it can also serve double duty as a chamber flag. Of course, this being MagnetoSpeed, their target market is going to be for the bolt action crowd. With that said, we're told that so far it has fit into every AR-15 and AR-10 style rifle that they've tried it in (.22LR not included!). Here's some more information from MagnetoSpeed: Tired of waiting and waiting for your rifle to cool down? MagnetoSpeed’s new barrel cooler, Riflekühl, is designed to get barrel temperatures down to intended operating levels quickly. The turbocharger inspired impeller is engineered to produce great air flow in a small package. Powered by a single CR123A Lithium battery (included), ambient air is forced through the extendable nozzle down the bore of the rifle. Designed to seal and push air flow down the barrel where it’s needed to efficiently cool barrels, typically under 7 minutes. Riflekühl doubles as a chamber flag and features an exclusive built-in air filter to prevent dust and dirt from being blown into your rifle. Spend less time waiting and more time shooting with the MagnetoSpeed Riflekühl. Other features include: ‣Replaceable dust filter (50 Microns) ‣Strong neodymium magnet secures device to chamber ‣Included CR123 lithium battery lasts for dozens of range sessions ‣Spring loaded retractable nozzle designed for compact and durable storage ‣Belt/Pocket clip included for easy carry ‣Chamber seal for increased cooling efficiency ‣Red body serves as an empty chamber flag Check out the video below or visit MagnetoSpeed online here for more information.
