Anyone using Caldwell's new Barrel Cooler?

I could maybe see that application, but this thing says its for AR15s. It plugs into the magwell.

In a year from now there might not be much else to spend your money on if we don't stop the liberal disease from spreading

Oh I get the idea...I just don't think it's practical. No way it cools enough in time to matter. I'd stick my barrel in an ice chest and then shake it out before I'd do this.

I understand the "every lit bit helps" state of mind, but I'm with you. The area of the exterior barrel surface is much greater than bore surface area.

I actually wish JP made smaller OD versions of those for government profile barrels. It's a great concept that adds a TON of surface area for a nominal increase in weight.

If i could fit them under my KMR, i totally would.
