There was a LOT of sweet stuff at the show, but nothing sweeter (to me) than this, from Otis Technology, INc:

A cleaning kit the size of a tennis ball, that (with a few extra brushes/patches) will cover any rifle. Hell, they make a kit that does anything, for about a hundred and a half. The nylon-covered aircraft cable is great, and it springs straight when you uncoil it. I want one of these, bad, and thankfully, you can buy them online.
