Barrel cooling device recommended to me by @Flea21 and @Mike.Hamilton0313
This thing has been awesome for cooling barrels, drying wet bores, and dust removal. Seems like a quality unit and I wish I would have had one of these long ago. Super compact and is very handy, very powerful little thing too.
Hope this helps a few of you. I did a few searches and didn't see much on these newer handheld units, only the mattress inflators.
link to product if you don't want to watch the video, just need some 1/2" ID tubing.
