Chamber Chiller Gun Barrel Cooling Fan Announced

Chamber Chiller Gun Barrel Cooling Fan Announced

30 NOVEMBER 2015 – Reno, NV: The firearms industry has been on fire in 2015, but it has also been a very hot year for outdoor shooters. For some, the competitive summer months caused equipment failures for shooters trying to push their rifle and cartridge to the mechanical limits. When steel becomes overheated the barrel harmonics change: vibration increases, and accuracy diminishes. Overheating is a problem for plenty of shooters, because a hot barrel also contributes to increased throat erosion and pressure failures.

Chamber Chiller BETA-50 Rifle Barrel Cooler

Shooters want a cool barrel, so that wear is minimized and accuracy is consistent. Using a 3D printer and commercially available components, avid long-range shooter Olin Coles has developed a product he calls the “Chamber Chiller” gun barrel cooling device, a product which he claims can give shooters in hot weather an edge over their competition. Designed to fit into the cartridge chamber of most bolt action and semi-automatic rifles, Chamber Chiller reduces the time is needed for cooling-down a hot barrel.


The concept is simple: Chamber Chiller cools inside the rifle chamber using a battery-powered ventilating system, where heat often sinks into the loaded cartridge causing higher pressure, and reduces temperatures to a safer level. Chamber Chiller draws air from outside the receiver and pushes it down the longest barrels, allowing for quicker recovery to optimal operating temperature.

Chamber Chiller is expected to first become available as a working prototype, with hand-built samples available to shooters as soon as Q2-2016. Visit https://www.chamberchiller.com for updates.
