Now shipping with new higher performance fans! This is our old model without power switch and battery strap guides.
The OMEGA-60 USB series utilizes an external USB power source and a 60mm fan for excellent barrel cooling in small bore rifles. This model will fit a mil-spec AR-15 and many other actions.
We recommend using Rayovac USB Chargers for powering your Chamber Chiller.

Standard USB A-Type Male Connector
60mm Turbo Fan
8.0 mm ID Nozzle (minimum port opening 41mm wide / 12.5mm tall) (1.61417 inches wide by 0.492126 inches tall)

Chamber Chiller OMEGA-60 USB is a well developed barrel cooler for rifles with minimum port opening 41mm wide and 12.5mm tall. OMEGA-60 is ideal for rifle cartridge rims measuring 9.6-12.0 mm. It is designed many for semi-automatic weapons with less clearance in the ejection port. In order to accommodate for the smaller ejection port a smaller nozzle and fan were required. Please check your port clearance before ordering.

Please Note:

The Chamber Chiller nozzle should only touch the outside edge of your chamber. The nozzle should not be inserted all of the way into the chamber.
