cool technique, it works well, I've though of it myself when I first started, and always used it. Got a craky amount of kills that way. the only problem is that it is a little bit tricky to go on the side of the gun. for example if you are right handed, tilting left is really easy, but tilting right is quite harder. you have to kindof bend over the gun. its not too bad when you are sanding up, but when you are prone it isn't easy!
