Description
BarrelCool is an empty chamber indicator and barrel cooling device that can be used in most bolt actions, AR-15, and AR-10/LR308 platforms.
I have found Barrelcool to be indispensable during load development with my competition rifles and especially when zeroing my hunting rifles, with their very thin barrels they tend to heat up extremely quickly, but now with Barrelcool I don’t have to sit around for 15 minutes waiting for the barrel to cool, I just put the barrel cooler in for 5 minutes and I’m ready to go.
