I just got done writing up a brief article for Army Times/ Gear Scout showing the IWC Hand Stop on the BCM Kino. The Kino has been off to the side for a little while as I've been using a 11.5" upper on my duty carbine. While working with the IWC hand stop paired up with the Kino, it reminded me of exactly why this setup is so nice. Light weight, great all around barrel length, and fantastic handling really come together for a slick setup. If it wasn't for me currently using folding sight/ slick top setups right now, I think this would make for a perfect all around duty rig.
Anyway, I know a bunch of guys love the Kino setup, so here is a link, and some pictures. For anyone on the fence, check it out, and go fire one if you can. If you can't do live fire, do some basic dry drills and room clear, and see if you don't have lust for Kino... wait, that just sounds wrong.
