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 we've created the “Chamber Chiller” rifle barrel cooling fan for both ejection ports and magazine wells.
After testing homemade and commercially-available barrel cooling devices, we discovered several key areas that could be improved for better performance and functionality. As a result, We designed and developed our own Chamber Chiller rifle barrel cooling fan devices. These are functional products produced on either SLS or FDM 3D printers or injection molded using a variety of durable materials.
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.
Chamber Chiller’s superior cooling performance has made it a high-demand product, and it will be on store shelves soon.
