(4 reviews) Write a Review


Tired of waiting and waiting for your rifle to cool down? MagnetoSpeed's new barrel cooler, RifleKuhl, 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. Riflekuhl doubles as a chamber flat 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 RifleKuhl. 


  • Retractable nozzle, locks in position, spring loaded
  • Strong neodymium magnet
  • Replaceable 50 micron filter
  • Chamber seal for efficient air flow
  • Metal belt clip on backside
  • CR123 Lithium Battery, provides an average of 50 Cooling Sessions

  • Barrel Cooler

    Really does works great. Definitely cuts down the time between groups when you want a cool barrel. My only complaint is it is a battery eater, A123/CR17345 type. But with that little fan blowing I guess that can be expected.

    Have used it several times seems to work ok but time will tell. Takes a little longer on heavy stainless barrells then advertized . Its handy and fits in my range bag without taking up any room. it also looks and works just as good as some of the contraptions I see some guys bringing to the range claiming they saved a whopping 20 bucks. Cmon Man.

    This is a very handy product. Moves a lot of air for it's size and really helps cool the barrel faster than just sitting. It was noisy to begin with but a little foam between the battery and the battery door sopped it from rattling and quieted it down.
