Just found this article that explains AR Gas System Lengths on the Texas Gun Forum. A very good discussion, I think -http://www.shootingillustrated.com/index.php/33740/ar-gas-system-lengths-explained/.

Good Article.

Though it is a video promoting a piston system, This Video starts out with a simulation of the D.I. gas flow path to give newbies a mental image of what's going on inside.
