The Caldwell AR-15 Accumax Barrel Cooler Fan locks into the magazine well on any AR-15 and forces cool air into the chamber and down the barrel to decrease cool down time. Ideal for use when testing loads for accuracy or between competition rounds of intense shooting, the fan is powered by a 12 volt rechargeable lithium ion battery and has a three to four hour runtime per charge.
