Magwell Chamber Chillers

Our Magwell Chamber Chillers utilize an AR-15, 308 or 338 magazine well to cool the rifles chamber and barrel. Our magwell models slightly out perform our ejection port models using the same electronics.

  • Chamber Chiller Magwell rifle barrel and chamber cooler
 

When metal heats, the molecules excite and cause expansion. When metal becomes overheated, barrel harmonics also change, vibration increases, and shots begin to vertically string. A hot barrel also contributes to pressure failures, and increased throat erosion. You want a cool barrel so that each shot is consistent, and wear is minimized. This is why I’ve created the “Chamber Chiller” rifle barrel cooling fan.

After testing homemade and commercially-available barrel cooling devices, I discovered several key areas that could be improved for better performance and functionality. As a result, I designed and developed my own Chamber Chiller rifle barrel cooling fan devices. These are functional products, each device is hand assembled with off-the-shelf parts or 3D printed parts right here in the United States.

The idea behind Chamber Chiller is simple: cool the chamber where heat often sinks into the loaded cartridge causing higher pressure, and deliver cool air down even the longest rifle barrel using a high-output fan. Impressive air volume forced past the barrel tenon at a high static pressure means much less time is needed for cooling-down, which also equals quicker recovery to optimal operating temperatures.

  • Efficiently cools the barrel and chamber
  • Helps maintain accuracy
  • Prolongs barrel life

We currently offer 4 ejection port models. Each model is available with either a traditional household AA alkaline battery pack or USB powered.
