My Barrel Cooler

If you rack your rifle vertically after shooting a volley, the hot barrel will act as a chimney and will pull cool air into the open chamber.

It's free and you don't need the extra gear.

While searching this forum and others for a decent solution to help cool down my rifle barrels during range sessions, this is what I have came up with. It is a culmination of ideas from others and a few of my own. It consists of temp strips from Grainger, a 12 volt mattress blower from WalMart ($10), some tubing, fittings and a modified case to fit tight in the chamber. It works really well, I can take the temp from 122-135 down to ambient in about 5-7 minutes. It was taking about 20-25 when the gun was vertical in the rack. The next test is to place the blower in a cooler with freezer ice packs.
