Chamber Cooler

I designed this to cool down the chamber and barrel after strings of fire to get you back on the target sooner. It's good for sighting in or load development. I've tested it in Rem 700, Win 70, Weatherby Vanguard and Ruger 111. It fits in both long and short action rifles.

It was designed around the GDSTime 75mmX15mm fan and I used the 5V model with USB plug so I could carry a rechargeable power pack to the range. You can swap for a 12V model and use batteries if you want even more airflow.
